How to tell if a transaction is active in a Java EE 6 interceptor?

Question

I am planning to write an interceptor for an EJB that will do basically the following:

@AroundInvoke
public Object setContext(InvocationContext ctx) throws E         


        

Answer 1

You can inject a TransactionSynchronizationRegistry and use getTransactionStatus to get the status of the transaction in the current context, it returns an int which is a contant in the Status class, in your case you are looking for STATUS_NO_TRANSACTION

Inject:

@Resource
TransactionSynchronizationRegistry tsr;

Check Transaction Status:

if (Status.STATUS_NO_TRANSACTION == tsr.getTransactionStatus()) {
   // no transaction
}
