Thanks for the reply Peter.
I am caching these pages after they are processed, but because of the nature
of the application, they are many different kinds of these pages.
Tomcat does not even throw an exception, I have allocated 128-356 mb memory.
It just dies and does not response to requests.
Here is the out put. I run it on command prompt.
D:\BOGODA\DEVELOPMENT\PRODUCTS\SERVLETS>javac HelloServlet.java

That's not a bad idea, I will look into.

Thnks it works fine.
But then why it not works after I set the class path
for the servlet-api.jar file using "Environment

It contains connectors, which allow a web server such as Apache HTTPD,
