[jboss-user] [JBoss Seam] - pass seam component to external ejb call causes exception [u

[leezard]

Hi all again,

My next seam problem is: I have an external ejb, I call to perform some operations. I have also set of classes delivered in separate jar. One of those classes was marked as seam component I couldn't do it via annotation so I added:

<component name="request" class="com.jboss.seam.test.TestTransactionRequest" auto-create="true" scope="CONVERSATION"/>

Now my bean code is: 

  | @Stateful
  | @Name("processTransactionRevoke")
  | @Scope(ScopeType.CONVERSATION)
  | public class ProcessTransactionRevokeBean implements ProcessTransactionRevoke {
  | 
  | 	private boolean revokeSuccesful;
  | 	
  | 	@Logger
  | 	private Log logger;
  | 	
  | 	@RequestParameter
  | 	String transactionId;
  | 	
  | 	@In
  | 	TestTransactionRequest request;
  |  	
  | 	@EJB
  | 	TransactionRevokeService service;
  | 	
  | 	@Begin(pageflow="transactionRevoke")
  | 	public void begin() {
  | 		logger.info("Begin called");
  | 		request.setParentTransaction(transactionId);
  | 		logger.info("Parent trid: " + request.getParentTransaction());
  | 	}
  | 	
  | 	public void revokeTransaction() {
  | 		logger.info("processing");
  | 		try {
  | 		        logger.info("Parent trid: " + request.getParentTransaction());
  | 			revokeService.revokeTransaction(revokeRequest, false);
  | 			revokeSuccesful = true;
  | 			logger.info("succeed");
  | 		} catch(Exception e) {
  | 			logger.info("failed");
  | 			e.printStackTrace();
  | 			revokeSuccesful = false;
  | 		}
  | 	}
  | 
  | 	public boolean isRevokeSuccesful() {
  | 		return revokeSuccesful;
  | 	}
  | 
  | 	@Remove @Destroy
  | 	public void destroy() {}	
  | }
  | 

Logs say that request is initialized and has parentTransaction set properly, but when I pass request to service.revokeTransaction method I get an exception saying:

What's wrong with it?
