Re: Class Cast Exception using return type as List

[Vaishakhi Ajmera]

Thanks for your reply Glen,
I tried using both the setReturnType and setReturnClass but still got the
ClassCastException
This is what my webservice looks like

import java.util.*;
//import com.ardec.ebf.usermgr.*;

public class UserList1
{
 private ArrayList userList=new ArrayList();

 public List getUserList()
 {
  userList.add(new String("Vaishakhi Ajmera"));
  userList.add(new String("Rabia Malik"));
  return userList;
 }

}
My client class calls the getUserList method. This is what the method that
calls the webservice in my client class looks like

protected String doExecute() throws Exception
   {
    String endpoint = "http://localhost:8080/axis/UserList1.jws";;

    Service  service = new Service();
      Call     call    = (Call) service.createCall();

      call.setTargetEndpointAddress( new java.net.URL(endpoint) );
      call.setOperationName( "getUserList" );

      call.setReturnClass( java.util.List.class );
      call.setReturnType(XMLType.SOAP_ARRAY);

      listOfUsers = (ArrayList) call.invoke( new Object [] {});


  return SUCCESS;
   }

So as you can see my webservice returns a List object. How do I make my
service return a SOAP array. I am ending you the code so that you can point
out anything that u see I am doing wrong. Hope this helps you solve my
problem.

This is great help and I surely appreciate it.
Thanks

Vaishakhi

Also, you need to specify both the return type and the return class, I
believe.
