After playing around with this for a while, I found that thest thing to do
is to use Javabeans to do the dtabae access. I don't know why you would need
an EJB, a simple JavaBean should be enough. I use one for selects and
inserts to the database, then I can call it from JSP and servlets.

Subject: Re: EJB and Tomcat/Servlet and JSP
First, would like to thank Christopher for pointing me to EJB sources.
Secondly, I have another question, if I want to build a web application,
mainly to access the database (delete/add/modify, etc). Should it be good
enough if I put these codes inside servlets, in other words, use servlets to
control the business logic as well as manipulate the database?
Or do I need to write my own EJB(s) to do this database manipulations? My
client will talk to the servlets, then the servlets will talk to EJB(s).
perhaps it is a 4 tiers architecture.
If that is the case, then I would need somthing like JBoss, which has Tomcat
embeded so that it can serve as a single engine for both servlets/jsp and
EJB all together.
Please recommend the way you would do.
Thanks much in advance.

Some J2EE implementations use Tomcat, but that's not
really on-topic for jsp-interest or servlet-interest.
You might try:
http://archives.java.sun.com/archives/j2ee-interest.html
or maybe:
http://archives.java.sun.com/archives/ejb-interest.html
You might also want to check out JBoss:
http://www.google.com/search?q=jboss
and, of course, Sun's J2EE reference implementation.
They both use Tomcat. (Hmmm, on second thought, not sure
about JBoss, but you ought to check it out anyway)
