Running this example before attempting to create your own EJBeans will show you the different steps involved. The example is a stateful session EJBean called TellerBean that contacts a Tuxedo Server using Jolt for WebLogic, and conducts transactions as follows:

• Contacts and calls a Tuxedo Server, and retrieves the returned results
• Uses a session EJBean
• Uses stateful persistence
• Uses application-defined exceptions and utilities
• Uses a client browser application

The client browser application performs these steps:

1. Contacts the teller home ("TellerHome") through JNDI to find the EJBean.
2. Creates a teller ("Terry").
3. The application then performs a series of transactions for the Teller that has just been created:
   • Gets the current balance for account 10000.
   • Performs Transaction 1: Deposits $100 into the account, and displays the balance.
   • Performs Transaction 2: Deposits $200 (more than the transaction limit of $300).

     Note:

     In Transaction 1, a single call is made, and is automatically committed. In Transaction 2, a begin() and commit() bracket two separate requests (a deposit and a withdrawal).
   • Attempts to withdraw $100 more than the balance of the account.
   • Catches an ApplicationException, retrieves the status messages embedded in the exception, and rolls back Transaction 2.
   • Gets the final balance for the account.
   • Removes the teller.

You can see in Transaction 2 how the balance is successfully rolled back to what it was at the end of Transaction 1.
