How to make wsconsume generate Serializable classes from WebService (WS) WSDL in JBoss EAP?

Issue

• How to make wsconsume generate Serializable classes from WebService (WS) WSDL in JBoss EAP?
• I'm getting an error : java.lang.RuntimeException: WFLYEJB0054: Failed to marshal EJB parameters
  and the cause is: java.io.NotSerializableException for a class that is generated from WSDL file.

• I created Java classes from wsdl by executing org.jboss.wsf.spi.tools.cmd.WSConsume in ant task. Snippet of the ant task is as below:

  <java classname="org.jboss.wsf.spi.tools.cmd.WSConsume" fork="true">
       <jvmarg value="-Djava.endorsed.dirs=${jboss_home}/lib/endorsed" />
       <arg line="-o ${build_dir}" />
       <arg line="-k " />
       <arg line="-t 2.1" />
       <arg line="-s ${everest_dir}/sources" />
       <arg line="${nmsapischema}/wsdl/nms.wsdl" />
       <classpath refid="classpath.wscomsume" />
  </java>
  

• Can you give me the details about how to create java classes that extend serializable.
