Determine Sender and Receiver in adapter module?

Question

All,
Non-XML messages from different senders are received via the same JMS queue.  In the text payload, the ID of the sender and receiver is contained.
Would it be technically possible to develop a JMS adapter module that sets the Sender Party, Sender Service, Receiver Party and Receiver Service based on the content of the message payload?  Is it possible to influence sender and receiver in an adapter module?
Kind regards, Guy Crets

Hi Steven,
It seems like you can not convince XI to pick up a new message. The code below works when you use "inputModuleData.setPrincipalData(msg);" but not with "inputModuleData.setPrincipalData(msgnew);".
The error in the Runtime Workbench is: "Catching exception calling messaging system' found, cause: javax.transaction.InvalidTransactionException: Cannot invoke call from within a transactional context.".
I tried to set the RefToMessageId on the new message, but this does not work either.
Does anybody know why the InvalidTransactionException is thrown?
Here is the example code:
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException
  try {
    Message msg = (Message) inputModuleData.getPrincipalData();
    Context ctx = new InitialContext();
    ConnectionFactory cf = (ConnectionFactory) ctx.lookup(
      com.sap.aii.af.ra.ms.api.ConnectionFactory.JNDI_NAME);
    MessageFactory  factory = cf.createMessageFactory("XI");
    Message  msgnew = factory.createMessage(
      msg.getFromParty(),msg.getToParty(),
      msg.getFromService(),msg.getToService(), msg.getAction());
    msgnew.setConversationId(msg.getConversationId());
    msgnew.setDocument(msg.getDocument());
    inputModuleData.setPrincipalData(msgnew);
  catch (Throwable t)
    ModuleException me = new ModuleException("MyException");
    throw me;
  return inputModuleData;
Best regards,
