I have recently tried to run tomcat on my machine & configured it for
basic paths.
Started the server.
Did a test run by loading an HTML file. ----> Which works fine.
Then I tested with JSP document. ---> It also loads fine.
Then when I tried to load a basic servlet.......It boomed....
Says "The requested resource not available".

Initially I had jsdk1.4, so someone suggested that Tomcat have some
issues with this jsdk version & will not load the servlets & I should
install jdk1.3.
And pursuant to resolve the issue I did the same & now again even
after installation of jkd1.3 the problem stayed.
