Hi

I'm trying to extend "HelloJazz"

https://jazz.net/learn/LearnItem.jsp?href=content/docs/hello-jazz/index.html

to be able to send Map<String, Object> object as well as String.
(">" is expressed to ">" in following sentences)

To achieve this, I added interface and impl to each package as follows.

- common package

Map<String, Object> sendMap(Map<String, Object> map) throws TeamRepositoryException;



- client package

Map<String, Object> sendMap(Map<String, Object> map) throws TeamRepositoryException;



- client internal package

public Map<String, Object> sendMap(Map<String, Object> map) throws TeamRepositoryException{

  Map<String, Object> newMap = getService().sendMap(map);

  return newMap;

}



- service package

public Map<String, Object> sendMap(Map<String, Object> map) throws TeamRepositoryException{

  Iterator<String> iter = map.keySet().iterator();

    while(iter.hasNext()){

      String key = iter.next();

      String value = (String)map.get(key);

      System.out.println("key:" + key+ ",value:" + value);

    }

  return map;

}

however I met this error by running these code...

com.ibm.team.repository.common.transport.ServiceMethodInvocationError: java.lang.ClassCastException: java.util.HashMap incompatible with org.eclipse.emf.ecore.EObject
at com.ibm.team.repository.transport.client.RemoteTeamService.getAppropriateException(RemoteTeamService.java:571)
at com.ibm.team.repository.transport.client.RemoteTeamService.executeMethod(RemoteTeamService.java:474)
at com.ibm.team.repository.transport.client.RemoteTeamService.invoke(RemoteTeamService.java:184)
at com.ibm.team.repository.transport.client.ServiceInvocationHandler.invoke(ServiceInvocationHandler.java:43)
...

This means complicated object(such as Map) cannot be sended in raw condition from client library to server side,
and some marshal steps are needed ?

If so, do we have to write marshaling methods by myself or some methods are prepared for this purpose ?

These 2 are my questions.

Thanks
