getting processes of package via CORABA?

Hi,

Can anybody tell me, how to get the processes of a package via corba interface?

The java code is:
	ExecutionAdministration ea = Shark.getInstance().getAdminInterface().getExecutionAdministration();
	ea.connect("admin", "enhydra", ENGINE_NAME, "");  
	WfProcessMgrIterator pmi = ea.get_iterator_processmgr();
	pmi.set_query_expression(" packageId .equals(\"" + packageId + "\")");
	WfProcessMgr[] procMgrs = pmi.get_next_n_sequence(0); 

Using .net and accessing the engine via corba, there is no "getAdminInterface" function.
So I use "AdminMisc" class.
But this Class has no "get_iterator_processmgr" function and when I cast it like this:

		public WFProcess[] getProcesses()
		{
			try
			{
				AdminMisc ea = wfEngine.getInstance.getAdminMisc();				
				ea.connect("admin", "enhydra", "Shark", "");

				WfProcessMgrIterator pmi = ((ExecutionAdministration) ea).get_iterator_processmgr();  // execption
				WfProcessMgr[] procMgrs = pmi.get_next_n_sequence(0);

				WFProcess[] procs = new WFProcess[procMgrs.Length];
				for (int i = 0; i < procMgrs.Length; i++)
				{

					procs[i] = new WFProcess(procMgrs[i]);
				}

				return procs;

			}
			catch (Exception ex)
			{
				System.Diagnostics.Debug.WriteLine(ex.Message);
				System.Diagnostics.Debug.WriteLine(ex.StackTrace);
			}		

			return new WFProcess[0];
		}

An Exception is thrown:

CORBA system exception : omg.org.CORBA.BAD_OPERATION, completed: Completed_MayBe minor: 0

Server stack trace: 
Exception rethrown at [0]: 
   at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
   at WorkflowService.ExecutionAdministration.get_iterator_processmgr()
   at NetControlMonitoringClient.Shark.WFProcessManager.getProcesses() in D:\VSProjects\NetControlMonitoringClient\NetControlMonitoringClient\Shark\WFProcessManager.cs:line 214

I can't find something helpful in the api documentation.
How is "getting processes of a package" done via CORBA?

Yes, shark admin application access the shark engine using corba. You can put the engine (shark corba server) on one computer and access it using the admin client from another one.
