27.3. Implementing the Service Provider

Generating the implementation code
Copia collegamento

You generate the implementation class used to build your service provider with the code generator's -impl flag.
Note
If your service's contract includes any custom types defined in XML Schema, you must ensure that the classes for the types are generated and available.
For more information on using the code generator see Section E.2, “cxf-codegen-plugin”.

Generated code

The implementation code consists of two files:
  • portTypeName.java — The service interface(SEI) for the service.
  • portTypeNameImpl.java — The class you will use to implement the operations defined by the service.

Implement the operation's logic
Copia collegamento

To provide the business logic for your service's operations complete the stub methods in portTypeNameImpl.java. You usually use standard Java to implement the business logic. If your service uses custom XML Schema types, you must use the generated classes for each type to manipulate them. There are also some Apache CXF specific APIs that can be used to access some advanced features.

Example

For example, an implementation class for the service defined in Example 26.1, “HelloWorld WSDL Contract” may look like Example 27.2, “Implementation of the Greeter Service”. Only the code portions highlighted in bold must be inserted by the programmer.

Example 27.2. Implementation of the Greeter Service

package demo.hw.server;

import org.apache.hello_world_soap_http.Greeter;

@javax.jws.WebService(portName = "SoapPort", serviceName = "SOAPService", 
                      targetNamespace = "http://apache.org/hello_world_soap_http", 
                      endpointInterface = "org.apache.hello_world_soap_http.Greeter")
                  
public class GreeterImpl implements Greeter {

    public String greetMe(String me) {
       System.out.println("Executing operation greetMe");
       System.out.println("Message received: " + me + "\n");
       return "Hello " + me;
    }
    
    public void greetMeOneWay(String me) {
       System.out.println("Executing operation greetMeOneWay\n");
       System.out.println("Hello there " + me);
    }

    public String sayHi() {
       System.out.println("Executing operation sayHi\n");
       return "Bonjour";
    }

    public void pingMe() throws PingMeFault {
       FaultDetail faultDetail = new FaultDetail();
       faultDetail.setMajor((short)2);
       faultDetail.setMinor((short)1);
       System.out.println("Executing operation pingMe, throwing PingMeFault exception\n");
       throw new PingMeFault("PingMeFault raised by server", faultDetail);
    }
