Re: Tomcat and Sun J2EE

[Pae Choi <pa...@earthlink.net>]

Hello Peter,

I am not sure what are you trying to do with both of them. First, J2EE
is a full range of development and deployment tools, including Web
Server, Application Server, J2EE APIs(JSP, Servlet, EJB, JMS, etc...)
, and even with Database. Once you configure and use them, you can
see the tomcat is included as well. And I like the "deploytool" in person
in some sense. :-)

Or, if you are having any trouble, you can forget the first option above
and just use the Apache/Tomcat to handle the Web Components such as
HTML, JSP, Servlet, and possibly Java Beans. and access the
Application Components such as EJBs, etc.. that interact with database.
Even though the EJB is not necessary to access the database.
So, it would be another option.

Hope this help.

Pae
