Hi, K&B
I am learning
EJB now, so exiting that your book has published
I have some questions about transaction in EJB.
1. What the different between "Container managed transaction" and "Database Managed Transaction"? that is what the diff between
"<tans-attribute>Required</trans-attribute>" and "connection.commit()"
,if I just have a singel database. which can provide better perfermance.
2. Is there any different between the transaction in Session bean and Entity bean?
3. If too many nesting transaction declaration in EJBs, for example EJBa call EJBb, and EJBb call EJBc, they all declared transaction required in their calling method,will the container optimize it?
thanks
