Create new transaction for a method of a SSB

[lvhuyen]

I have a Stateless Session Bean named ManagerEJB with a method name insert(..), in which, I create 3 entities AEJB, BEJB and CEJB. But when I fail to create a BEJB (with an exception I catched), in my database, still have a new row of table A.
In my ejb-jar.xml file, I have had the following declaration:
<container-transaction>

<ejb-name>ManagerEJB</ejb-name>
<method-name>*</method-name>

<trans-attribute>Required</trans-attribute>
</container-transaction>
All of my entities bean and session bean are CMT.

Please help me!
Thanks

Enhance ManagerEJB with the following field and method:

private javax.ejb.SessionContext sessionCtxt = null;

public void setSessionContext( javax.ejb.SessionContext ctxt )
{
this.sessionCtxt = ctxt;
}

in catch-block of the exception:
this.sessionCtxt.setRollbackOnly();

This will cause a rollback instead of a commit when leaving the SessionBean method.
