    problems calling webservices from a Stateless Session Bean

      I'm calling webservices from a stateless session bean, which returns an array of user defined objects(complex types) and it returns me a "No deserializer defined for array type " exception. This works fine, if I just use a normal J2SE client.

      My environment(webservices client) is JBOSS 3.2.1 + apache axis + SLSB.

      http://www.jboss.org/wiki/Wiki.jsp?page=WSClientAppl says how to do this but I've some questions.

      1) How do I generate the jaxrpc-mapping.xml file from a wsdl file?
      2) where do I add the service-ref tags?
      3) How do I package my jar file?
      4) can someone please post a small example or tell me the issues with my example here?

      ArrayOfUserDefinedObjects.jar
 com.webservices.client.complex_types.ArrayOfUserDefinedObjectsRemoteHome
 com.webservices.client.complex_types.ArrayOfUserDefinedObjectsRemote
 com.webservices.client.complex_types.ArrayOfUserDefinedObjectsBean
 com.webservices.server.complex_types.ArrayOfUserDefinedObjects
 com.webservices.server.complex_types.ArrayOfUserDefinedObjectsService
 com.webservices.server.complex_types.ArrayOfUserDefinedObjectsServiceLocator
 com.webservices.server.complex_types.ArrayOfUserDefinedObjectsSoapBindingImpl
 com.webservices.server.complex_types.ArrayOfUserDefinedObjectsSoapBindingStub
 com.webservices.server.complex_types.ArrayOfUserDefinedObject
 META-INF/ejb-jar.xml
 META-INF/jboss.xml
 META-INF/ArrayOfUserDefinedObjects.wsdl





      
/**
 * ArrayOfUserDefinedObjectsRemoteHome.java
 */

package com.webservices.client.complex_types;

public interface ArrayOfUserDefinedObjectsRemoteHome extends javax.ejb.EJBHome {
 public javax.ejb.EJBObject create() throws javax.ejb.CreateException, java.rmi.RemoteException;
}





      /**
 * ArrayOfUserDefinedObjectsRemote.java
 */

package com.webservices.client.complex_types;

public interface ArrayOfUserDefinedObjectsRemote extends javax.ejb.EJBObject {
 public com.webservices.server.complext_types.ArrayOfUserDefinedObject[] getArrayOfUserDefinedObjects(String[] arrInput) throws RemoteException;
}

package com.webservices.client.complex_types;

public class ArrayOfUserDefinedObjectsBean implements javax.ejb.SessionBean {
 public com.webservices.server.complext_types.ArrayOfUserDefinedObject[] getArrayOfUserDefinedObjects(String[] arrInput) {
 try {
 com.webservices.server.complex_types.ArrayOfUserDefinedObjects objArrayOfUserDefinedObjects = new com.webservices.server.complex_types.ArrayOfUserDefinedObjectsServiceLocator().getArrayOfUserDefinedObjects();

 return objArrayOfUserDefinedObjects.getArrayOfUserDefinedObjects(arrInput);
 } catch(Exception e) {
 e.printStackTrace();
 }
 }

 public void ejbPassivate() throws EJBException {}
