Using the Session Bean

We are already familiar with looking up home interfaces and using them to create beans, and then using beans.  Everything is identical in this case, but there is no method to find by a primary key.

There is a sample file included here that shows how to access the session bean.  Again, there are two versions of the file, SessionClientSample.java for JDK 1.2 and SessionClientSample.java for JDK 1.3.  The JDK 1.2 version does not use PortableRemoteObject.

Remember to add your StockQuoteEjb.jar file to the classpath, before compiling and using the sample client.

Try running the client program without the stock-quotes file being present.  This should cause the EJB to throw a java.io.IOException to the client program.  Now put the stock-quotes file in place and run the program.  Now it should correctly return the prices.

Exercise:   Write and test a client program for your bank-accounts EJB that lets you query balances, and credit and debit some amounts to to the balances.
