>From what I have read Enterprise level applications
are headed to 3 or 4 tiers. Tier 1 is the client (browser)
Tier two is the Web server coupled with a container for presentation logic.
Tier three is optional and is a container for business logic (ie.
Enterprise Java Beans )
Tier four is the database/ data repository.
The basic idea is to separate the data from the presentation (display)
tomcat is a web server add on that provides a container for the
presentation
logicby supporting JSP & servletts. It works with several web servers-
Apache, IIS among them. It is built on java and has versions for
Linux/Unix and
windows. It can run on the same machine or a different machine than the
webserver.
In fact, different contex can be on different machines.
You can of course skip the EJB tier and put JDBC inside the jsp or
servletts
if you consider a full blown EJB container as overkill. If tomcat evolves,
I expect it to merge with the web servers as built in. Not in the
direction
of EJB. Also check out cocoon - an XML-Java document system.
