"Enterprise JavaBeans: Developing Component-Based
Distributed Applications"
by Tom Valesky
http://www.amazon.com/exec/obidos/ASIN/0201604469/wendysmallIf you're tired of the long view of Enterprise JavaBeans
(EJBs) in some other titles, check out this guide to
creating reusable server-side components. "Enterprise
JavaBeans" from Tom Valesky provides hands-on guidance to
programming with EJBs. Filled with working sample code and a
guide to writing several kinds of EJBs (from session beans
to entity beans), this is the book to turn to if you're
faced with developing with EJBs for a real project with real
deadlines.
