Hi
I am going through the Professional EJB.I am implementing the examples of this book. In chapter 4 one example is given for BMP bean. I have implemented that one. Deployment of BMP is successfull. And while runnign the client "TaxClient" the following exception is thrown.
This was throen at the statement
tax = home.create("IL", 5.00f);
The ejbCreate() method in the TaxEJB got executed completly, I put the debug statements. So the error is at client side only.
Why it is trowing this exception while returning teh stateCode.

Please help me...
The exception is as follows...

Caught an exception.

ption is:
