Also, please see the ServletsFaq for more tips.

I think every thing is ok abt deployment descriptor and there is no need of the lib files ,only the folder lib is enough.

Please use real words when posting to the forums. Abbreviations such as "abt" in place of "about" only serve to make your posts more difficult to read and less likely to generate useful responses.

and there is no need of the lib files ,only the folder lib is enough.

I have no idea what you mean by that.

But if you check the ServletsFaq you will see that one problem you have is that the servlet class is not in a package.

Hi ,


Your class is not servlet , as HelloWorldServlet the one you have written is not extending HttpServlet.

So this class will not get any servletness and second thing is in the deployment descriptor the package name is not menltioned.

Good call on the missing extends / implements clause, I hadn't even noticed.

[soven rout]

sorry even if after implementing the servlet class ,the 404 error is coming and no change in the error and I don't get the "Hello Web World " in the tomcat console .

[Rob Spoor]

1) Why don't you extend HttpServlet like Chetan suggested?
2) Have you put the servlet class in a package already?

Hi Soven ,

Please check the below links these might help you

Also can you check whether you are getting context itself or not .Then only hit the servlet pattern after that.

If you are not getting your context helloworldapplication then might be problem with project setup.

If you have created dynamic web project then check for the Build path(should be classes folder in the WEB-INF ) and the servlet jars in the lib folder
