User Txn - Lookup problem

[Shivaji Bhosale]

From my simple Java Class client, I want to initiate User Txn. Server CMPs have Txn attributes as TX_REQUIRED.
Say I am carrying out 5 Txns, & say 3rd one is failed, then previous 2 must be rolled back & next Txns must be abandoned.
Since my client is not a Session Bean, I have code like this, for having UserTransaction.
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, factory);
ht.put(Context.PROVIDER_URL, url);
InitialContext ctx = new InitialContext(ht);
javax.transaction.UserTransaction userTrans =
(javax.transaction.UserTransaction)ctx.lookup("javax.transaction.UserTransaction");
But at this lookup I get an error NoSuchNameFoundException.
Right now I am doing this all in IBM VAJ which is having Websphere Test Environment. I have Name Server & Bean Servers running.
What is the problem? If URL is wrong ?
Waiting eagerly for replies...

The JNDI name isn't right. Lookup "jta/usertransaction" instead.
