A CMR collection may only be used within the transction in w

[thepriz]

I am using JBoss 3.2.3 with nukes 1.0 In a nukes module I do something similar and it works but in a service bean that I create this does not work. I get the CMR collection error.

 NoteEJBLocal note = noteHome.create(currentPackage, noteNumber, startTime, stopTime, remarks);

 Collection eventLogs = note.getEventLogs();
 EventLogEJBLocal eventLog = EventUtils.logEvent(null, "Note Created", "", "");
 eventLogs.add(eventLog);
 note.setEventLogs(eventLogs);

The reason I don't put the eventLog in the create is that I want to make sure the create is successful before I create the event. It dies on the eventLogs.add(eventLog) line. It gives me the error "A CMR collection may only be used within the transction in which it was created". What am I doing wrong? As I have said it works doing this exact same thing in a nukes module.

In the deployment-descriptor of your SessionBean you either declare wether to use container managed or bean managed transaction demarcation.

In case of container managed transaction, check if the trans-attribute is e.g. "Required".

In case of bean managed TX, programmatically obtain the UserTransaction object and start the transaction.

I am using CMP. I use ant to create the descriptors. I found that

* @ejb.transaction
* type="Required"
*

this is in the declaration. I believe this is like this because we are using a Oracle database. How can I get this to work?

Hello thepriz,
Have you resolved this problem?
I meet the same problem.

Make sure that both beans ( the session bean and the entity bean) declare that a transaction is "required". Then all of the 'internal' CMP entity bean operations should run in the same transaction of the 'outer' session bean. The container will create a transaction before invokation of your session bean method and will reuse this transaction for all embeded entity operations.
