Hi Pooja,
Try to provide more info./expln on u problem, u q is not clear, but i
understood it like below
u want map to three tables, three cmp's under single transaction
if i am write, read the following stuff from weblogic
Calling multiple EJBs from a single transaction context
In the following code fragment, a client application obtains a
UserTransaction object and uses it to begin and commit a transaction. The
client invokes two EJBs within the context of the transaction. The
transaction attribute for each EJB has been set to Required:
import javax.transaction.*;
...
u = (UserTransaction)
jndiContext.lookup("javax.transaction.UserTransaction");
u.begin();
account1.withdraw(100);
account2.deposit(100);
u.commit();
...
In the above code fragment, updates performed by the "account1" and
"account2" EJBs occur within the context of a single UserTransaction - they
commit or roll back as a logical unit. This is true regardless of whether
"account1" and "account2" reside on the same WebLogic Server, multiple
WebLogic Servers, or a WebLogic Server cluster.
The only requirement for wrapping EJB calls in this manner is that both
"account1" and "account2" must support the client transaction - the beans'
trans-attribute element must be set to Required, Supports, or Mandatory.
