outside the scope of a transaction

[Stefan Groschupf <sg...@media-style.com>]

Hi,

I use cactus to test my ejbs in weblogic 8.1 sp2.
There something i could not find any starting point to track down the  
problem.

I have in my test case a line:
  assertEquals(0,  
KitUtil.getLocalHome().findByPrimaryKey(kitLocal.getUniqueSequence()).ge 
tSubscribers().size());
At least I just test a entity n:n entity bean relation in this line.
I got this exception:

[junit]     Caused an ERROR
     [junit] [EJB:010116]Attempted to access the collection valued  
cmr-field, 'subscribers', for bean, 'Kit', outside the scope of a  
transaction. All access to the collection must be performed during the  
transaction in which the collection was initially retrieved.
     [junit] java.lang.IllegalStateException: [EJB:010116]Attempted to  
access the collection valued cmr-field, 'subscribers', for bean, 'Kit',  
outside the scope of a transaction. All access to the collection must  
be performed during the transaction in which the collection was  
initially retrieved.


I was asking already the bea support guys but they suggest do not use  
this kind of strange tools since .... ;-o
They say the the cactus servlet will not run inside a transaction and  
my findbyprimary key run every-time in a transaction.
Thats way there will be no solution for this problem. ;(

I do not comment this answer. ;-(

Anyway it is difficult for me to test my ejbs in case I can not use the  
getter methods that returns collections of other enitity beans.
So far was able to workaround by testing the content of my DTO that was  
generated by a DTOFactory session bean, where I have no problems at  
all.

Someone has any idea what I can do to test getter methods collections  
of entity bean i was finding by primary key?

Thanks for any hints.
Stefan

Re: ... a transaction, reset caller principal

[Stefan Groschupf <sg...@media-style.com>]

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

Hi 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.
