Two thoughts:
1: startup time can be further shrunk by lightly editing the config to
remove the default load balancing app and the like.
2: I do all this using eclipse + MyEclipse, and I've found it quite

How are you logging in your servlets? Are you using
System.out/System.err? If so, don't use them, and instead use the

Actually, they are mostly beans with no ServletContext :(

Hi,
Yes, you need to modify web.xml. The url-pattern in the servlet-mapping
element is relative to the context root. For the URL you say want, put
in /cbiservlet instead of the current value.
Also, I suggest you put your servlet in a package, e.g. com.cbir or
whatever.

"dispatch" refers to the RequestDispatcher class which you use to do a

So the sequence could be something like the following:
-> LoginServlet (validated) (dispatch)-> MainServlet (dispatch)-> *.jsp
It'd look like your page that the MainServlet returned was coming direct

It's not always a bad idea. As usual, if you share your design and give
some more concrete details, we may be able to help more.
In an Model2 sort of architecture like Struts, you would use this to
forward to your presentation JSP file. So, no, I don't think it is a bad idea.

Hi,
The WEB-INF/classes and WEB-INF/lib directories are where you can deploy
servlets and other compiled Java things for your web application. This
is not a tomcat-specific structure, it's part of the Servlet
Specification. And it hasn't changed from tomcat 4.0 to 4.1.
However, some other things
As a short-term work-around, try going to the /work directory and
manually compile the page_JSP.JAVA file there. I can't get JSPs to
automatically compile, but if I do them manually the next time they are
called they work fine. (It seems even with no changes you may have to
recompile them if
