Thank you for the quick reply . I am having problem with deploying web application in Netbeans 6.5 with Tomcat 6.0. I have all the services running of Apache server and also have configured it with my project but it is giving "the requested resource not found error" in my browser.The issue is that I have installed Apache HTTPd server but it is not shown in add server service of netbeans. I want to knw what resources does it is actually seeking for to run my application although it is built successfully.

I guess you missing mod_jk module. Have look at this article , but as far I'm aware there been some issues with trying to put together Tomcat6 and Apache2 with use of this module, however maybe somebody solved it...
