Configuring the cxf-se-su service unit

4.04. Creating cxf-se service unit 4. Beginner - Web services with ServiceMix and CXF 

On this page, we are going to configure the cxf-se-su service unit to provide our webservice .

Configuring the pom.xml

First of all we need to move into the created folder my-cxf-se-su.

Changing the project name

In order to make the build output a little bit more comprehensible we first change the project name in the generated pom.xml file.

 
<project>
  ...
  <name>CXF WSDL Tutorial :: CXF SE SU</name>
  ...
</project>



Adding version of cxf to pom.xml



We must specify the version of CXF to use:





 
<project>
...
  <properties>
    ...
	<cxf-version>2.0.7</cxf-version>
    ...
  </properties>
...
</project>



 


Adding the org.apache.cxf plugin



We add this plugin to the generated pom.xml file to element plugins.





<plugin>
   <groupId>org.apache.cxf</groupId>
   <artifactId>cxf-codegen-plugin</artifactId>
   <version>${cxf-version}</version>
           <executions>
              <execution>
                  <phase>generate-sources</phase>
                  <configuration>
                      <sourceRoot>${basedir}/target/jaxws</sourceRoot>
                      <wsdlOptions>
                          <wsdlOption>
                              <wsdl>${basedir}/src/main/resources/service.wsdl</wsdl>
                              <extraargs>
                                  <extraarg>-verbose</extraarg>
                              </extraargs>
                          </wsdlOption>
                      </wsdlOptions>
                  </configuration>
                  <goals>
                     <goal>wsdl2java</goal>
                  </goals>
               </execution>
           </executions>
   </plugin>






This plugin is used for generating java classes from the WSDL file. We use the wsdl2java tool from JAX-WS (CXF framework).

The next step is to copy the WSDL file we already made in the my-cxf-bc-su to the my-cxf-se-su because we need it to generate

the java classes from it. So copy it now:


    
	
  • from folder: my-cxf-bc-su/src/main/resources
    • 
	
  • to folder:   my-cxf-se-su/src/main/resources
    • 





Implementing generated ExampleService.java



We must implement our service in java. In directory src/main/java/org/apache/servicemix/examples is generated java file ExampleService.java. 

So, we must rename this file to HelloImpl.java and change its content on this:



HelloImpl.java


package org.apache.servicemix.examples;

import javax.jws.WebService;
import javax.xml.ws.Holder;

import org.apache.servicemix.examples.types.SayHello;
import org.apache.servicemix.examples.types.SayHelloResponse;

@WebService(serviceName = "HelloService", targetNamespace = "http://servicemix.apache.org/examples", endpointInterface = "org.apache.servicemix.examples.Hello")
public class HelloImpl implements Hello {

    public void sayHello(Holder<String> name)
        throws UnknownWordFault
    {
        if (name.value == null || name.value.length() == 0) {
           org.apache.servicemix.examples.types.UnknownWordFault fault = new org.apache.servicemix.examples.types.UnknownWordFault();
            throw new UnknownWordFault(null, fault);
        }
 
      name.value = "Hi " + name.value;
    }

}





Configuring xbean.xml



Next we have to configure our new SU to really provide some webservice. We do this by modifying the file 

named xbean.xml in the src/main/resources directory of our my-cxf-se-su module:





<cxfse:endpoint>
   <cxfse:pojo>
      <bean class="org.apache.servicemix.examples.HelloImpl" />
   </cxfse:pojo>
</cxfse:endpoint>






Next, we are going to create service assembly.



Things to remember


    
	
  • You specify the plugin for a SU in Maven's pom.xml file
    • 
	
  • In ServiceMix, most service units will be configured by a file named xbean.xml
    •
