Hi,
I have a question related to EJB and Transactions. I wrote two Entity
( Container Managed ) beans each will create a row in two separate
tables of a same pool.Its necessary to create two rows at the same time
with different tables otherwise it will become inconsistent.
For this requirement is it necessary to use
javax.transaction.Transaction class ? it the servlet ( which calls two
EJBs ).
I wrote the servlet like this.
Context octx = getInitialContextForOrder();
Context pctx = getInitialContextForPayment();
// Using userTransaction
transaction =
(UserTransaction)octx.lookup("javax.transaction.UserTransaction");
transaction.begin();
StoreOrderHome ohome = (StoreOrderHome)
octx.lookup("storeorder");
StoreOrder oremote = (StoreOrder)
ohome.create(orderno,ammount,paid);
PaymentHome phome =
(PaymentHome)pctx.lookup("storepaymentinfo");
Payment premote = (Payment)
phome.create(customerid,ammount,orderno,paid);
transaction.commit();
without using Transacton .begin() and commit() also no difference.
Is this right way to use Transaction class ? how to use rollback() and
remaining methods with the EJB's itself.
waiting for ur help.
