New project skeletons can be generated using code.quarkus.redhat.com.

Quarkus CXF is a part of Quarkus Platform since Quarkus Platform version 3.1.0.Final. Among other things, this means that code.quarkus.redhat.com and other Quarkus development tools generate projects with proper dependency management:

<project ...>
  ...
  <properties>
    ...
    <quarkus.platform.artifact-id>quarkus-bom</quarkus.platform.artifact-id>
    <quarkus.platform.group-id>com.redhat.quarkus.platform</quarkus.platform.group-id>
    <quarkus.platform.version><!-- Check the latest https://maven.repository.redhat.com/ga/com/redhat/quarkus/platform/quarkus-cxf-bom/ --></quarkus.platform.version>

      </dependency>
    </dependencies>
  </dependencyManagement>
...

We recommend to proceed with any of the following chapters:

Having the pom.xml in place, you can add a simple Hello world! Web service in src/main/java.

First add the service interface:

package io.quarkiverse.cxf.it.server;

import jakarta.jws.WebMethod;
import jakarta.jws.WebService;

/**
 * The simplest Hello service.
 */
@WebService(name = "HelloService", serviceName = "HelloService")
public interface HelloService {

    @WebMethod
    String hello(String text);

}

and then the implementation:

package io.quarkiverse.cxf.it.server;

import jakarta.jws.WebMethod;
import jakarta.jws.WebService;

/**
 * The simplest Hello service implementation.
 */
@WebService(serviceName = "HelloService")
public class HelloServiceImpl implements HelloService {

    @WebMethod
    @Override
    public String hello(String text) {
        return "Hello " + text + "!";
    }

}

For the implementation to get exposed under a certain path, you need to add the following configuration to application.properties:

# The context path under which all services will be available
quarkus.cxf.path = /soap

# Publish "HelloService" under the context path /${quarkus.cxf.path}/hello
quarkus.cxf.endpoint."/hello".implementor = io.quarkiverse.cxf.it.server.HelloServiceImpl
quarkus.cxf.endpoint."/hello".features = org.apache.cxf.ext.logging.LoggingFeature

With these files in place, you can start Quarkus in dev mode:

$ mvn quarkus:dev

This will compile the project and start the application on the background.

You can test the service using curl or some other SOAP client.

First let’s have a look at the auto-generated WSDL under http://localhost:8080/soap/hello?wsdl:

$ curl http://localhost:8080/soap/hello?wsdl
<?xml version='1.0' encoding='UTF-8'?>
<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema"

  </wsdl:message>
  <wsdl:portType name="HelloService">
    <wsdl:operation name="hello">
      <wsdl:input message="tns:hello" name="hello">
    </wsdl:input>
      <wsdl:output message="tns:helloResponse" name="helloResponse">
    </wsdl:output>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="HelloServiceSoapBinding" type="tns:HelloService">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="hello">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="hello">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="helloResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="HelloService">
    <wsdl:port binding="tns:HelloServiceSoapBinding" name="HelloServicePort">
      <soap:address location="http://localhost:8080/soap/hello"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

Second, let’s send a SOAP request to the service:

$ curl -v -X POST -H "Content-Type: text/xml;charset=UTF-8" \
    -d \
      '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <soap:Body><ns2:hello xmlns:ns2="http://server.it.cxf.quarkiverse.io/"><arg0>World</arg0></ns2:hello></soap:Body>
       </soap:Envelope>' \
    http://localhost:8080/soap/hello
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns1:helloResponse xmlns:ns1="http://server.it.cxf.quarkiverse.io/">
      <return>Hello World!</return>
    </ns1:helloResponse>
  </soap:Body>
</soap:Envelope>

You can see the expected <return>Hello World!</return> in the SOAP response.

Sometimes it may come in handy to be able to inspect the SOAP messages received or sent by the server or client. This is easily doable by adding the quarkus-cxf-rt-features-logging extension to pom.xml.

<dependency>
    <groupId>io.quarkiverse.cxf</groupId>
    <artifactId>quarkus-cxf-rt-features-logging</artifactId>
</dependency>

quarkus.cxf.endpoint."/hello".features=org.apache.cxf.ext.logging.LoggingFeature

After that you can send a new SOAP request and see some SOAP payloads in the application console:

2023-01-11 22:12:21,315 INFO  [org.apa.cxf.ser.Hel.REQ_IN] (vert.x-worker-thread-0) REQ_IN

You may want to proceed with packaging your application for running on a JVM or natively.

First, we need some remote Web service to connect to. We can use a simple Calculator Web service running in a container for that purpose.

$ docker run -p 8082:8080 quay.io/l2x6/calculator-ws:1.0

Once the container is up and running, we can inspect its WSDL

$ curl -s http://localhost:8082/calculator-ws/CalculatorService?wsdl
<?xml version="1.0" ?>
<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://www.jboss.org/eap/quickstarts/wscalculator/Calculator" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" name="CalculatorService" targetNamespace="http://www.jboss.org/eap/quickstarts/wscalculator/Calculator">

  ...

  <wsdl:binding name="CalculatorServiceSoapBinding" type="tns:CalculatorService">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"></soap:binding>
    <wsdl:operation name="add">
      <soap:operation soapAction="" style="document"></soap:operation>
      <wsdl:input name="add">
        <soap:body use="literal"></soap:body>
      </wsdl:input>
      <wsdl:output name="addResponse">
        <soap:body use="literal"></soap:body>
      </wsdl:output>
    </wsdl:operation>
    <wsdl:operation name="subtract">
      <soap:operation soapAction="" style="document"></soap:operation>
      <wsdl:input name="subtract">
        <soap:body use="literal"></soap:body>
      </wsdl:input>
      <wsdl:output name="subtractResponse">
        <soap:body use="literal"></soap:body>
      </wsdl:output>
    </wsdl:operation>

    ...

  </wsdl:binding>

  ...

</wsdl:definitions>

As you can see in the WSDL, the service offers some basic arithmetic operations, such as add, subtract, etc.

Let’s test it with curl:

$ curl -s \
    -X POST \
    -H "Content-Type: text/xml;charset=UTF-8" \
    -d \
        '<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
            <Body>
                <add xmlns="http://www.jboss.org/eap/quickstarts/wscalculator/Calculator">
                    <arg0 xmlns="">7</arg0> 1
                    <arg1 xmlns="">4</arg1>
                </add>
            </Body>
        </Envelope>' \
    http://localhost:8082/calculator-ws/CalculatorService
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns2:addResponse xmlns:ns2="http://www.jboss.org/eap/quickstarts/wscalculator/Calculator">
      <return>11</return> 2
    </ns2:addResponse>
  </soap:Body>
</soap:Envelope>

Now let’s have a look how we can get the client inside a Quarkus application.

First, we need the Service Endpoint Interface (SEI) and all other model classes it requires.

There are several ways to get them:

The last option tends to be the easiest and most flexible for client applications.

In our case, the Service Endpoint Interface (SEI) is org.jboss.eap.quickstarts.wscalculator.calculator.CalculatorService.

As usual on Quarkus, we can obtain an instance of it via CDI.

To make it testable easily, we’ll wrap it in a REST service:

package io.quarkiverse.cxf.client.it;

import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.QueryParam;
import jakarta.ws.rs.core.MediaType;

import org.jboss.eap.quickstarts.wscalculator.calculator.CalculatorService;

import io.quarkiverse.cxf.annotation.CXFClient;

@Path("/cxf/calculator-client")
public class CxfClientRestResource {

    @CXFClient("myCalculator") 1
    CalculatorService myCalculator;

    @GET
    @Path("/add")
    @Produces(MediaType.TEXT_PLAIN)
    public int add(@QueryParam("a") int a, @QueryParam("b") int b) {
        return myCalculator.add(a, b); 2
    }

}

Is this all we need for the client to work? - No, in addition to the above, we need to tell a few other things to the CXF Quarkus extension in application.properties:

cxf.it.calculator.baseUri=http://localhost:8082
quarkus.cxf.client.myCalculator.wsdl = ${cxf.it.calculator.baseUri}/calculator-ws/CalculatorService?wsdl
quarkus.cxf.client.myCalculator.client-endpoint-url = ${cxf.it.calculator.baseUri}/calculator-ws/CalculatorService
quarkus.cxf.client.myCalculator.service-interface = org.jboss.eap.quickstarts.wscalculator.calculator.CalculatorService

With all the above files in place, we should be able to start the application in Quarkus dev mode

$ mvn quarkus:dev
...
INFO  [io.quarkus] (Quarkus Main Thread) ... Listening on: http://localhost:8080

and test it by sending some requests to it:

$ curl -s 'http://localhost:8080/cxf/calculator-client/add?a=5&b=6'
11

where 11 is the correct result of adding 5 and 6.

You may want to proceed with

Several configuration options of Quarkus CXF allow referring to beans present in Quarkus CDI container. Features and interceptors are typical examples of those.

There are two ways how to set a bean reference in the configuration: by type or by bean name.

# bean reference by type
quarkus.cxf.endpoint."/hello".features = org.apache.cxf.ext.logging.LoggingFeature

# bean reference by bean name
quarkus.cxf.endpoint."/fruit".features = #myCustomLoggingFeature

import org.apache.cxf.ext.logging.LoggingFeature;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;

class Producers {

    @Produces
    @ApplicationScoped
    @Named("myCustomLoggingFeature")
    LoggingFeature myCustomLoggingFeature() {
        LoggingFeature loggingFeature = new LoggingFeature();
        loggingFeature.setPrettyLogging(true);
        return loggingFeature;
    }
}

In the introductory guides for SOAP client and SOAP service, we worked only in Quarkus dev mode: Quarkus tooling was running on the background, watching for changes in our workspace, recompiling and reloading the application as needed.

How do we run the application on a JVM once we are done with the development?

First we need to package it with Maven:

$ mvn package

The libraries needed to run the application on a JVM can be found in target/quarkus-app directory:

$ ls -lh target/quarkus-app
drwxr-xr-x. 2 ppalaga ppalaga 4.4K Jan 12 22:29 app
drwxr-xr-x. 4 ppalaga ppalaga 4.4K Jan 12 22:29 lib
drwxr-xr-x. 2 ppalaga ppalaga 4.4K Jan 12 22:29 quarkus
-rw-r-r--. 1 ppalaga ppalaga 6.1K Jan 12 22:29 quarkus-app-dependencies.txt
-rw-r-r--. 1 ppalaga ppalaga  678 Jan 12 22:29 quarkus-run.jar

We can start the application as follows:

$ java -jar target/quarkus-app/quarkus-run.jar

You can send some SOAP requests using curl to make sure that the application works.

Quarkus offers first class support for building GraalVM native images and Quarkus CXF fully honors that promise too.

The pom.xml file generated by code.quarkus.redhat.com contains the native profile needed for building the native image:

<profile>
  <id>native</id>
  <activation>
    <property>
      <name>native</name>
    </property>
  </activation>
  <properties>
    <skipITs>false</skipITs>
    <quarkus.package.type>native</quarkus.package.type>
  </properties>
</profile>

Further, as mentioned in the creating a project section, you need the GraalVM native-image tool.

Either install it locally or set your GRAALVM_HOME environment appropriately, or — if you only need to produce a Linux native executable — you can use docker.

# Make sure $GRAALVM_HOME is set properly
$ echo $GRAALVM_HOME
/home/{user}/.sdkman/candidates/java/{major}.{minor}.r{java-version}-grl

# Produce the native executable
mvn package -Pnative

# Produce the native executable
mvn package -Pnative -Dquarkus.native.container-build=true

This can take a minute or so for a simple application.

When the build is done, the native executable should be available in target directory:

$ ls -l target
...
-rwxr-xr-x. 1 ppalaga ppalaga  71M Jan 11 22:42 quarkus-cxf-integration-test-server-1.8.0-SNAPSHOT-runner
...

As you can see, it has a size of only 71 MB, and is executable.

You can run it as follows:

$ target/*-runner
...
INFO  [io.quarkus] (main) quarkus-cxf-integration-test-server 1.8.0-SNAPSHOT native (powered by Quarkus
2.15.2.Final) started in 0.042s. Listening on: http://0.0.0.0:8080
...

Again, you can send some SOAP requests using curl to make sure that the native executable works.

Do not forget to compare the memory usage, time to first request and other performance metrics with the stack you used before and share your results!

You may also refer to the links below which contain tips on how to work with native images.

Refer to Quarkus Container image guide.

The payload logging functionality is implemented primarily through the org.apache.cxf.ext.logging.LoggingFeature class.

There are several ways how you can set the feature on a client or service endpoint.

To attach an instance with default settings, you can do one of the following:

import org.apache.cxf.ext.logging.LoggingFeature;
import jakarta.enterprise.context.ApplicationScoped;
import jakarta.enterprise.inject.Produces;

class Producers {

    @Produces
    @ApplicationScoped
    @Named("limitedLoggingFeature") // "limitedLoggingFeature" is redundant if the name of the method is the same
    LoggingFeature limitedLoggingFeature() {
        LoggingFeature loggingFeature = new LoggingFeature();
        loggingFeature.setPrettyLogging(true);
        loggingFeature.setLimit(1024);
        return loggingFeature;
    }
}

# For a service:
quarkus.cxf.endpoint."/hello".features = #limitedLoggingFeature
# For a client:
quarkus.cxf.client.hello.features = #limitedLoggingFeature

JAXB is a reflection based serialization framework. When learning about GraalVM native images, one of the first things you typically hear is that you have to register classes, fields and methods for reflection at build time. With plain GraalVM you’d have to do this through reflection-config.json manually. Well, at least for the classes you have written yourself. Not so with Quarkus. quarkus-jaxb extension (which quarkus-cxf depends on) is able to scan your application’s class path for classes annotated with JAXB annotations and register them for reflection automatically.

Hence working with complex payloads on Quarkus is not different from stock CXF. The JAXB serialization and deserialization will work out of the box without any additional configuration.

The Service Endpoint Interface (SEI) for managing fruits might look like the following:

package io.quarkiverse.cxf.it.server;

import java.util.Set;

import jakarta.jws.WebMethod;
import jakarta.jws.WebService;

@WebService
public interface FruitService {

    @WebMethod
    Set<Fruit> list();

    @WebMethod
    Set<Fruit> add(Fruit fruit);

    @WebMethod
    Set<Fruit> delete(Fruit fruit);
}

We can implement the SEI as simply as possible:

package io.quarkiverse.cxf.it.server;

import java.util.Collections;
import java.util.LinkedHashSet;
import java.util.Set;

import jakarta.jws.WebService;

@WebService(serviceName = "FruitService")
public class FruitServiceImpl implements FruitService {

    private Set<Fruit> fruits = Collections.synchronizedSet(new LinkedHashSet<>());

    public FruitServiceImpl() {
        fruits.add(new Fruit("Apple", "Winter fruit"));
        fruits.add(new Fruit("Pineapple", "Tropical fruit"));
    }

    @Override
    public Set<Fruit> list() {
        return fruits;
    }

    @Override
    public Set<Fruit> add(Fruit fruit) {
        fruits.add(fruit);
        return fruits;
    }

    @Override
    public Set<Fruit> delete(Fruit fruit) {
        fruits.remove(fruit);
        return fruits;
    }
}

The implementation is pretty straightforward and you just need to define your endpoints using the application.properties.

quarkus.cxf.endpoint."/fruits".implementor = io.quarkiverse.cxf.it.server.FruitServiceImpl
quarkus.cxf.endpoint."/fruits".features = org.apache.cxf.ext.logging.LoggingFeature

Having the above files in place, you can start Quarkus tooling in dev mode:

$ mvn quarkus:dev
...
INFO  [io.quarkus] (Quarkus Main Thread) ... Listening on: http://localhost:8080

and then check whether the service is working by invoking its list operation:

$ curl -v -X POST -H "Content-Type: text/xml;charset=UTF-8" \
    -d \
      '<soapenv:Envelope
      xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
      xmlns:ns1="http://server.it.cxf.quarkiverse.io/">
        <soapenv:Body>
            <ns1:list/>
        </soapenv:Body>
    </soapenv:Envelope>' \
    http://localhost:8080/soap/fruits
...
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns1:listResponse xmlns:ns1="http://server.it.cxf.quarkiverse.io/">
      <return xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
        <description>Winter fruit</description>
        <name>Apple</name>
      </return>
      <return xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
        <description>Tropical fruit</description>
        <name>Pineapple</name>
      </return>
    </ns1:listResponse>
  </soap:Body>
</soap:Envelope>

As you can see, the endpoint has returned the two fruits Apple and Pineapple available by default.

Now let’s add another fruit, say an Orange:

$ curl -v -X POST -H "Content-Type: text/xml;charset=UTF-8" \
    -d \
     '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <soap:Body>
          <ns2:add xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
            <arg0>
              <description>Mediterranean fruit</description>
              <name>Orange</name>
            </arg0>
          </ns2:add>
       </soap:Body></soap:Envelope>' \
    http://localhost:8080/soap/fruits
...
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns1:addResponse xmlns:ns1="http://server.it.cxf.quarkiverse.io/">
      <return xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
        <description>Winter fruit</description>
        <name>Apple</name>
      </return>
      <return xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
        <description>Tropical fruit</description>
        <name>Pineapple</name>
      </return>
      <return xmlns:ns2="http://server.it.cxf.quarkiverse.io/">
        <description>Mediterranean fruit</description>
        <name>Orange</name>
      </return>
    </ns1:addResponse>
  </soap:Body>
</soap:Envelope>

We can see Orange having been added in the returned list as expected.

You may want to proceed with packaging your application for running on a JVM or natively.

If your client is going to communicate with a server whose SSL certificate is not trusted by the client’s operating system, then you need to set up a custom trust store for your client. Tools like openssl or Java keytool are commonly used for doing that. You may want to check someexamples in Quarkus CXF source tree.

Once you have prepared the trust store, you need to configure your client to use it.

keystore.type = jks 1
quarkus.cxf.client.hello.client-endpoint-url = https://localhost:${quarkus.http.test-ssl-port}/services/hello
quarkus.cxf.client.hello.service-interface = io.quarkiverse.cxf.it.security.policy.HelloService
quarkus.cxf.client.hello.trust-store-type = ${keystore.type}

quarkus.cxf.client.hello.trust-store = client-truststore.${keystore.type}
quarkus.cxf.client.hello.trust-store-password = password

The server SSL configuration is driven by Quarkus HTTP layer a.k.a. Vert.x. Quarkus HTTP guide provides the information about the configuration options.

Here is a basic example:

1
quarkus.http.ssl.certificate.key-store-file = localhost.${keystore.type}
quarkus.http.ssl.certificate.key-store-password = password
quarkus.http.ssl.certificate.key-store-key-alias = localhost
quarkus.http.ssl.certificate.key-store-key-password = password

The requirement for the clients to connect through HTTPS can be defined in a policy.

The functionality is provided by quarkus-cxf-rt-ws-security extension.

Here is an example of a policy file:

<?xml version="1.0" encoding="UTF-8"?>
<wsp:Policy xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy"
    xmlns:sp="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <wsp:ExactlyOne>
        <wsp:All>
            <sp:TransportBinding>
                <wsp:Policy>
                    <sp:TransportToken>
                        <wsp:Policy>
                            <sp:HttpsToken RequireClientCertificate="false" />
                        </wsp:Policy>
                    </sp:TransportToken>
                    <sp:IncludeTimestamp />
                    <sp:AlgorithmSuite>
                        <wsp:Policy>
                            <sp:Basic128 />
                        </wsp:Policy>
                    </sp:AlgorithmSuite>
                </wsp:Policy>
            </sp:TransportBinding>
        </wsp:All>
    </wsp:ExactlyOne>
</wsp:Policy>

The policy has to be referenced from a service endpoint interface (SEI):

package io.quarkiverse.cxf.it.security.policy;

import jakarta.jws.WebMethod;
import jakarta.jws.WebService;

import org.apache.cxf.annotations.Policy;

/**
 * A service implementation with a transport policy set
 */
@WebService(serviceName = "HttpsPolicyHelloService")
@Policy(placement = Policy.Placement.BINDING, uri = "https-policy.xml")
public interface HttpsPolicyHelloService extends AbstractHelloService {

    @WebMethod
    @Override
    public String hello(String text);

}

With this setup in place, any request delivered over HTTP will be rejected by the PolicyVerificationInInterceptor:

ERROR [org.apa.cxf.ws.pol.PolicyVerificationInInterceptor] Inbound policy verification failed: These policy alternatives can not be satisfied:
 {http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702}TransportBinding: TLS is not enabled
 ...

Use the following client configuration options provided by quarkus-cxf extension to pass the username and password for HTTP basic authentication:

Here is an example:

quarkus.cxf.client.basicAuth.wsdl = http://localhost:${quarkus.http.test-port}/soap/basicAuth?wsdl
quarkus.cxf.client.basicAuth.client-endpoint-url = http://localhost:${quarkus.http.test-port}/soap/basicAuth
quarkus.cxf.client.basicAuth.username = bob
quarkus.cxf.client.basicAuth.password = bob234

By default, the clients created by Quarkus CXF do not send the Authorization header, unless you set the quarkus.cxf.client."clients".secure-wsdl-access to true:

quarkus.cxf.client.basicAuthSecureWsdl.wsdl = http://localhost:${quarkus.http.test-port}/soap/basicAuth?wsdl
quarkus.cxf.client.basicAuthSecureWsdl.client-endpoint-url = http://localhost:${quarkus.http.test-port}/soap/basicAuthSecureWsdl
quarkus.cxf.client.basicAuthSecureWsdl.username = bob
quarkus.cxf.client.basicAuthSecureWsdl.password = ${client-server.bob.password}
quarkus.cxf.client.basicAuthSecureWsdl.secure-wsdl-access = true

The server-side authentication and authorization is driven by Quarkus Security, especially when it comes to

There is a basic example in our Client and server integration test. Its key parts are:

package io.quarkiverse.cxf.it.auth.basic;

import jakarta.annotation.security.RolesAllowed;
import jakarta.jws.WebService;

import io.quarkiverse.cxf.it.HelloService;

@WebService(serviceName = "HelloService", targetNamespace = HelloService.NS)
@RolesAllowed("app-user")
public class BasicAuthHelloServiceImpl implements HelloService {
    @Override
    public String hello(String person) {
        return "Hello " + person + "!";
    }
}

If you omit the client-endpoint-url property in application.properties, the CXF Quarkus extension will assume that the service is published at http://localhost:8080/{service-path}, where {service-path} is derived from

Given quarkus.cxf.path = /ws, the default effective client-endpoint-url of the CalculatorService would be http://localhost:8080/ws/org.jboss.eap.quickstarts.wscalculator.calculator.calculatorservice.

If quarkus.cxf.path is not specified, the client-endpoint-url would be just http://localhost:8080/org.jboss.eap.quickstarts.wscalculator.calculator.calculatorservice.

In the example above, we configured just a single client called myCalculator. Of course, you can configure multiple clients pointing at different URLs and/or implementing different SEIs using multiple identifiers:

cxf.it.calculator.baseUri = http://localhost:8082
quarkus.cxf.client.myCalculator.wsdl = ${cxf.it.calculator.baseUri}/calculator-ws/CalculatorService?wsdl
quarkus.cxf.client.myCalculator.client-endpoint-url = ${cxf.it.calculator.baseUri}/calculator-ws/CalculatorService
quarkus.cxf.client.myCalculator.service-interface = org.jboss.eap.quickstarts.wscalculator.calculator.CalculatorService

# another client
quarkus.cxf.client.anotherCalculator.wsdl = https://acme.com/ws/WeatherService?wsdl
quarkus.cxf.client.anotherCalculator.client-endpoint-url = https://acme.com/ws/WeatherService
quarkus.cxf.client.anotherCalculator.service-interface = org.jboss.eap.quickstarts.wscalculator.calculator.CalculatorService

To globally configure all clients in your application, you can use the example snippet below to configure the HttpConduit. This allows you to set the HTTPClientPolicy, AuthorizationPolicy, ProxyAuthorizationPolicy or even TLSClientParameters for your clients.

void onStart(@Observes StartupEvent ev) {

     HTTPConduitConfigurer httpConduitConfigurer = new HTTPConduitConfigurer() {
         public void configure(String name, String address, HTTPConduit c) {
             AsyncHTTPConduit conduit = (AsyncHTTPConduit)c;
             // use setter to configure client
             conduit.getHttpAsyncClient().getCredentialsProvider().setCredentials( AuthScope.ANY,
              new NTCredentials( USER,PWD, "", DOM ) );
             conduit.getClient().setAllowChunking( false );
             conduit.getClient().setAutoRedirect( true );
         }
     };

     final Bus bus = BusFactory.getDefaultBus();
     bus.setExtension(httpConduitConfigurer, HTTPConduitConfigurer.class);
}

Quarkus batch (e.g. periodically scheduled), or command line applications, may do without an HTTP server. Use the property below to prevent launching the HTTP server at startup:

quarkus.http.host-enabled = false

CXF client proxies implement java.io.Closeable. Therefore, it is important to call ((Closeable) proxy).close() once the client is not needed anymore to free all associated system resources, such as threads.

Quarkus CXF takes care for closing the clients injected via @io.quarkiverse.cxf.annotation.CXFClient automatically as soon as they are disposed by the CDI container.

For client proxies created manually, it is up to you to call ((Closeable) proxy).close():

import java.net.URL;
import javax.xml.namespace.QName;
import jakarta.xml.ws.Service;
import java.io.Closeable;

final URL serviceUrl = new URL("http://localhost/myService?wsdl");
final QName qName = new QName("http://acme.org/myNamespace", "MyService");
final Service service = jakarta.xml.ws.Service.create(serviceUrl, qName);
final MyService proxy = service.getPort(MyService.class);

try {
    proxy.doSomething();
} finally {
    ((Closeable) proxy).close();
}

A SOAP service is described by WSDL. It is a contract defining operations, their parameters and return values, etc. WSDL is rich enough to be used for generating the code of a complete client. CXF provides the wsdl2java utility for that.

Quarkus CXF wraps wsdl2java in the quarkus-cxf extension so you do not need to use it directly.

Follow the Generate the Model classes from WSDL section of the user guide for more details about how to use it.

You may also want to check the CXF Developing a Consumer as a general introduction.

When implementing a service the generation of Java code from WSDL may also come in handy. wsdl2java can generate the model classes (with JAXB annotations) and service interfaces (with JAX-WS annotations) for you. Your task is then to provide implementations for those interfaces.

You may want to check the WSDL First Service Development section of CXF documentation for a better understanding of the underlying concepts.

Another valid option at your disposal is to write your service in Java, using JAX-WS and JAXB. Then you have two options how to obtain the WSDL contract:

Passing custom parameters to wsdl2java is possible through quarkus.cxf.codegen.wsdl2java.additional-params configuration parameter.

If you need different additional-params for each WSDL file, you may want to define a separate named parameter set for each one of them. Here is an example:

# Parameters for foo.wsdl
quarkus.cxf.codegen.wsdl2java.foo-params.includes = wsdl/foo.wsdl
quarkus.cxf.codegen.wsdl2java.foo-params.wsdl-location = wsdl/foo.wsdl
# Parameters for bar.wsdl
quarkus.cxf.codegen.wsdl2java.bar-params.includes = wsdl/bar.wsdl
quarkus.cxf.codegen.wsdl2java.bar-params.wsdl-location = wsdl/bar.wsdl
quarkus.cxf.codegen.wsdl2java.bar-params.xjc = ts

Sometimes a REST endpoint may be needed in the same project where the Quarkus CXF Extension is used. The REST endpoint path must be different from the SOAP endpoint path (in order to avoid request forwarding conflicts between both protocols).

For example, if a WeatherWebService interface is declared in a WSDL, you can begin by creating the org.acme.cxf.WeatherWebServiceImpl class as follows:

package org.acme.cxf;

import ...

@Slf4j
@WebService(endpointInterface = "org.acme.cxf.WeatherWebService")
public class WeatherWebServiceImpl implements WeatherWebService {

    @Inject
    BackEndWeatherService backEndWeatherService;

    private Map<String, DailyTemperature> dailyTempByZipCode = Collections.synchronizedMap(new LinkedHashMap<>());

    public WeatherWebServiceImpl() {
        this.dailyTempByZipCode.addAll(
        		this.backEndWeatherService.getDailyForecast(Instant.now()));
    }

    @Override
    public DailyTemperature estimationTemperatures(String zipCode) {
        log.info("Daily estimation temperatures forecast called with '{}' zip code paramter", zipCode);
        return this.dailyTempByZipCode.get(zipCode);
    }
}

After that, you would need to specify the root context for your CXF web services, as indicated in the configuration documentation to split the REST (with RESTEasy for example) and SOAP routes based on their root context paths.

CXF’s SOAP properties:

quarkus.cxf.path=/soap
quarkus.cxf.endpoint."/weather".implementor=org.acme.cxf.WeatherWebServiceImpl

Now, imagine the following RESTEasy endpoint:

package org.acme.reasteasy;

import ...

@Slf4j
@Path("/healthcheck")
public class HealthCheckResource {

	@Inject
    BackEndWeatherService backEndWeatherService;

	@GET
	public Response doHealthCheck() {
		if(this.backEndWeatherService.isAvailable()) {
            return Response.ok().build();
		} else {
            return Response.status(Response.Status.SERVICE_UNAVAILABLE);
		}
	}
}

You can separate your REST endpoint by configuring the REASTEasy path:

quarkus.resteasy.path=/rest

You can now send requests to both your REST and SOAP endpoints deployed within a single project, at:

Sometimes the wsdl2java autogenerated Java classes may not be fully compatible with GraalVM due to non ASCII characters getting included in the code. Similar exceptions to the below may appear during native image builds.

Below is an example of auto-generated non ASCII characters in a Java class:

@XmlType(name = "OperationOrderStatusType")
@XmlEnum
public enum OperationOrderStatusType {

    @XmlEnumValue("Cr\u00e9\u00e9")
    CRÉÉ("Cr\u00e9\u00e9"),

    A_COMMUNIQUER("A communiquer"),

Anything starting with \u will be a problem. Consequently the following refactoring is needed:

    ANNULE("Annulé");
    private final String value;

    OperationOrderStatusType(String v) {
        value = v;

    public String value() {

    public static OperationOrderStatusType fromValue(String v) {
        for (OperationOrderStatusType c: OperationOrderStatusType.values()) {
            if (c.value.equals(v)) {
                return c;
            }
        }
        throw new IllegalArgumentException(v);
    }
}
