I posted my problem to the struts-user mailing list.

On a suggestion from PinoyJUG, I downloaded the Sun J2EE 1.3.1 reference implementation. for my EJB practice. Perhaps this time, I'll need a paper book to guide me. Until today, I have never purchased a single paper book on Java. I have "Algorithms and Data Structures in Java", but that is a Computer Science book.
