Chapter 44. Maven Tooling Reference
44.1. Plug-in Setup
Abstract
before you can use the Apache CXF plug-ins, you must first add the proper dependencies and repositories to your POM.
Dependencies
You need to add the following dependencies to your project’s POM:
the JAX-WS frontend
<dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>version</version> </dependency>the HTTP transport
<dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http</artifactId> <version>version</version> </dependency>the Undertow transport
<dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http-undertow</artifactId> <version>version</version> </dependency>
44.2. cxf-codegen-plugin
Abstract
Generates JAX-WS compliant Java code from a WSDL document
Overview
Basic example
The following POM extract shows a simple example of how to configure the Maven cxf-codegen-plugin to process the myService.wsdl WSDL file:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>3.3.6.fuse-7_13_0-00015-redhat-00001</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<configuration>
<sourceRoot>target/generated/src/main/java</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>src/main/resources/wsdl/myService.wsdl</wsdl>
</wsdlOption>
</wsdlOptions>
</configuration>
<goals>
<goal>wsdl2java</goal>
</goals>
</execution>
</executions>
</plugin>Basic configuration settings
In the preceding example, you can customize the following configuration settings
configuration/sourceRoot-
Specifies the directory where the generated Java files will be stored. Default is
target/generated-sources/cxf. configuration/wsdlOptions/wsdlOption/wsdl- Specifies the location of the WSDL file.
Description
The wsdl2java task takes a WSDL document and generates fully annotated Java code from which to implement a service. The WSDL document must have a valid portType element, but it does not need to contain a binding element or a service element. Using the optional arguments you can customize the generated code.
WSDL options
At least one wsdlOptions element is required to configure the plug-in. The wsdlOptions element’s wsdl child is required and specifies a WSDL document to be processed by the plug-in. In addition to the wsdl element, the wsdlOptions element can take a number of children that can customize how the WSDL document is processed.
More than one wsdlOptions element can be listed in the plug-in configuration. Each element configures a single WSDL document for processing.
Default options
The defaultOptions element is an optional element. It can be used to set options that are used across all of the specified WSDL documents.
If an option is duplicated in the wsdlOptions element, the value in the wsdlOptions element takes precedent.
Specifying code generation options
To specify generic code generation options (corresponding to the switches supported by the Apache CXF wsdl2java command-line tool), you can add the extraargs element as a child of a wsdlOption element. For example, you can add the -impl option and the -verbose option as follows:
...
<configuration>
<sourceRoot>target/generated/src/main/java</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
<!-- you can set the options of wsdl2java command by using the <extraargs> -->
<extraargs>
<extraarg>-impl</extraarg>
<extraarg>-verbose</extraarg>
</extraargs>
</wsdlOption>
</wsdlOptions>
</configuration>
...
If a switch takes arguments, you can specify these using subsequent extraarg elements. For example, to specify the jibx data binding, you can configure the plug-in as follows:
...
<configuration>
<sourceRoot>target/generated/src/main/java</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
<extraargs>
<extraarg>-databinding</extraarg>
<extraarg>jibx</extraarg>
</extraargs>
</wsdlOption>
</wsdlOptions>
</configuration>
...Specifying binding files
To specify the location of one or more JAX-WS binding files, you can add the bindingFiles element as a child of wsdlOption—for example:
...
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
<bindingFiles>
<bindingFile>${basedir}/src/main/resources/wsdl/async_binding.xml</bindingFile>
</bindingFiles>
</wsdlOption>
</wsdlOptions>
</configuration>
...Generating code for a specific WSDL service
To specify the name of the WSDL service for which code is to be generated, you can add the serviceName element as a child of wsdlOption (the default behaviour is to generate code for every service in the WSDL document)—for example:
...
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
<serviceName>MyWSDLService</serviceName>
</wsdlOption>
</wsdlOptions>
</configuration>
...Generating code for multiple WSDL files
To generate code for multiple WSDL files, simply insert additional wsdlOption elements for the WSDL files. If you want to specify some common options that apply to all of the WSDL files, put the common options into the defaultOptions element as shown:
<configuration>
<defaultOptions>
<bindingFiles>
<bindingFile>${basedir}/src/main/jaxb/bindings.xml</bindingFile>
</bindingFiles>
<noAddressBinding>true</noAddressBinding>
</defaultOptions>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
<serviceName>MyWSDLService</serviceName>
</wsdlOption>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myOtherService.wsdl</wsdl>
<serviceName>MyOtherWSDLService</serviceName>
</wsdlOption>
</wsdlOptions>
</configuration>
It is also possible to specify multiple WSDL files using wildcard matching. In this case, specify the directory containing the WSDL files using the wsdlRoot element and then select the required WSDL files using an include element, which supports wildcarding with the * character. For example, to select all of the WSDL files ending in Service.wsdl from the src/main/resources/wsdl root directory, you could configure the plug-in as follows:
<configuration>
<defaultOptions>
<bindingFiles>
<bindingFile>${basedir}/src/main/jaxb/bindings.xml</bindingFile>
</bindingFiles>
<noAddressBinding>true</noAddressBinding>
</defaultOptions>
<wsdlRoot>${basedir}/src/main/resources/wsdl</wsdlRoot>
<includes>
<include>*Service.wsdl</include>
</includes>
</configuration>Downloading WSDL from a Maven repository
To download a WSDL file directly from a Maven repository, add a wsdlArtifact element as a child of the wsdlOption element and specify the coordinates of the Maven artifact, as follows:
...
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdlArtifact>
<groupId>org.apache.pizza</groupId>
<artifactId>PizzaService</artifactId>
<version>1.0.0</version>
</wsdlArtifact>
</wsdlOption>
</wsdlOptions>
</configuration>
...Encoding
(Requires JAXB 2.2) To specify the character encoding (Charset) used for the generated Java files, add an encoding element as a child of the configuration element, as follows:
...
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
</wsdlOption>
</wsdlOptions>
<encoding>UTF-8</encoding>
</configuration>
...Forking a separate process
You can configure the codegen plug-in to fork a separate JVM for code generation, by adding the fork element as a child of the configuration element. The fork element can be set to one of the following values:
once- Fork a single new JVM to process all of the WSDL files specified in the codegen plug-in’s configuration.
always- Fork a new JVM to process each WSDL file specified in the codegen plug-in’s configuration.
false- (Default) Disables forking.
If the codegen plug-in is configured to fork a separate JVM (that is, the fork option is set to a non-false value), you can specify additional JVM arguments to the forked JVM through the additionalJvmArgs element. For example, the following fragment configures the codegen plug-in to fork a single JVM, which is restricted to access XML schemas from the local file system only (by setting the javax.xml.accessExternalSchema system property):
...
<configuration>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/wsdl/myService.wsdl</wsdl>
</wsdlOption>
</wsdlOptions>
<fork>once</fork>
<additionalJvmArgs>-Djavax.xml.accessExternalSchema=jar:file,file</additionalJvmArgs>
</configuration>
