public class Client
extends java.lang.Object
This class demonstrates calling an entity EJBean, followed by two exercises:

Part A: Create an Account and Deposit some money into it. Next attempt to withdraw more than the current account balance. An application-specific exception should be thrown. Finally, remove the account.

Part B: Create some new accounts, with different initial balances. Find all the accounts with a balance greater than a specific value. Find the account with a balance of zero. Attempt to find accounts with a null balance. Finally, remove all newly created accounts.

This class also illustrates how to lookup an EJB home in the JNDI tree.
