I have been having difficulties getting my code to work properly. This is
what I come up with when I try to run my client program (simple test program
that has four methods, add(int a, int b), subtract, multiply, divide ...
etc..
It looks as though the bean gets deployed and bound fine but I cannot
resolve this issue when running the client program:
Caught an unexpected exception!

Here is the pertient code:
/*
InitialContext ctx = new InitialContext();
Object logObj = (Object)ctx.lookup("ejb/CalculatorBean");
CalculatorHome home = (CalculatorHome)PortableRemoteObject.narrow(
logObj, CalculatorHome.class);
Calculator calc = home.create();
*/
InitialContext init = new InitialContext();
CalculatorHome home = (CalculatorHome)init.lookup("ejb/CalculatorBean");
Calculator calc = home.create();
If I use either of those, the same problem occurs. I will say that I am not
sure what classes I should be importing to provide me my CalculatorHome and
Calculator classes. I have recently started programming for J2EE and have
done so in the J2EE RI only. It returns a client.jar file for use with the
client. This exact program and bean works great in J2EE RI.
Thank you for your help,
