Thanks for the advice, i'm reading actually the book for second time to take the exam, and it is very, very good. I'm wonder what version of servlets and jsp uses the book. Again, thanks for this marvelous book.
Congratulations Mike, this is a very good score. Andrew in his book recomends generate stubs for a RMI solution, but maybe the people of sun forget to check this because since Java 5 generates the stubs dinamically.
