ASSIGNMENT:
Write a client on which the user can decide to buy or sell stocks. Stocks have an initial nominal value of 10€. and are bought or sold in grops of 10 at the time.
The user initially has a fixed amount of money (say 1000 €) and a given amount of stocks (say 50). Amount of money and number os stocks are saved in a database, which the client accesses via Hybernate.

In a loop, the user is asked if s/he wants to buy or sell stocks. The current value of the stocks is looked up in a stateless EJB, which returns a value that exhibits some small random fluctuation in time, up to +/- 5% of the fixed nominal value. After each iteration, the values in the DB are updated, and the total amount of money and stocks is shown to the user, until the user, instead of buying or selling again, quits. .

Get familiar with the JPQL (see http://docs.oracle.com/javaee/6/tutorial/doc/bnbtg.html)
