My client-mapping.xml file is generated by wstools. Here is the Ant task that performs the generation: <!-- Define a taskdef for the wstools ant task --> | <taskdef name="wstools" classname="org.jboss.ws.tools.ant.wstools"> | <classpath refid="build.classpath" /> | </taskdef> | | <target name="generate.ws.client"> | <wstools dest="${dir.gend}" config="wstools-client-config.xml" /> | </target> Note that the build.classpath contains jbossws-client.jar. Here is the wstools-client-config.xml: <?xml version="1.0" encoding="UTF-8"?> | <configuration xmlns:jbos="http://www.jboss.org/jbossws-tools"> | <wsdl-java file="wsdl/ClientService.wsdl"> | <mapping file="client-mapping.xml"/> | </wsdl-java> | </configuration> All the task does is look at my WSDL file and generate the client-mapping.xml. This client-mapping.xml file contains information about how to map XML to Java objects. Does that answer your question?
