Re: ... a transaction, reset caller principal

[Stefan Groschupf]

Hi Kazuhito,
thank you that helped very much!
I notice a strange side effect.
After closing the transaction my caller principal is reseted.
So I use the authentication mechanism described in cactus doc and it 
working fine in my test method until i start / commit the transaction.
Someone have any idea what kind of relation transactions and the caller 
principal have in weblogic?

Thanks
Stefan

As the error message says, you need to begin transaction
to access to the collection (retrived for n:n relation).
For example, I have used codes for CMR test with JBoss like follows:
    public class CmrTestCase
        extends ServletTestCase
    {
        protected UserTransaction transaction = null;
        protected beginTransaction(){
            if(transaction==null){
                transaction = 
(UserTransaction)context.lookup("java:comp/env/UserTransaction");
            }
	    transaction.begin();
        }
        protected commitTransaction(){
            if(transaction==null){
                return;
            }
            if(transaction.getStatus()==Status.STATUS_ACTIVE){
                transaction.commit();
            }
        }

        public void testXXX(){
            beginTransaction();
            // test codes for CMR etc.
            commitTransaction();
        }
    }
Hope this helps.
