finally i agreed that it is better to use IBM server with IBM tools.
i have a question to ask, it is enough to use websphere studio advanced edition if i want to develop JSP, Servlet & Javabean?
seems VAJ professional edition is included in the Websphere studio package
thanks!

hi kyle, but i don't think that IBM tools are easy to use.
"much better" means JBuilder is much better than VAJ as an IDE....
