Invoking a BPEL Process via Java Remote Client

Question

Hi everyone!
I want to invoke a BPEL process from my Java Application which is not running on the same Application-Server (not the same Java RE) as the BPEL processmanager does.
For Applications running on the same AS there is the IDeliveryService class to which you can send a XML-request in order to invoke a BPEL process.
Is the only way to invoke a BPEL Process from an external application to use a webservice client or is there a similar class for java remote clients?
For access to the users worklist I use
IWorkflowServiceClient wfClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
it works fine an I thought there might be a similar way to invoke a bpel process via remote too.
If anyone knows if it's possible or not please tell me ;)
Thanks in advance
Markus

Hello,
Here is the code I use:
Properties props = new Properties();
Locator locator = null;
props.put("orabpel.platform", "ias_10g" );
props.put("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory" );
props.put("java.naming.provider.url","opmn:ormi://host:port/orabpel" );
props.put("java.naming.security.principal", "adminuser" );
props.put("java.naming.security.credentials", "mdp" );
String securityCredentials = "adminuser";
String selectedDomain = "default";
locator = new Locator(selectedDomain,securityCredentials,props);
IBPELProcessHandle procs[] = locator.listProcesses();
The error is:
Exception in thread "main" java.rmi.UnmarshalException: Error deserializing return-value: java.io.InvalidClassException: com.oracle.bpel.client.BPELProcessHandle; local class incompatible: stream classdesc serialVersionUID = 5429682712928177644, local class serialVersionUID = 8176841433835717563
at com.oracle.bpel.client.util.ExceptionUtils.handleServerException(ExceptionUtils.java:82)
at com.oracle.bpel.client.Locator.listProcesses(Locator.java:309)
Thanks for help.
