Every time i deploy my servlet but still when I m directing it it shows page not found wats the error in java

Answer 1

If your deploy is success, there is not error in java.
First: You need to check on your admin console that it was deployed on the sever.
Second: If was deployed on the server, then check what context root is for your web application
Third: You need to check what the servlet's url-pattern is.
(At your web application directory, look the two xml files inside the WEB-INF directory).
Example:
Suppose that your web application has context-root named like "servlets" and your servlet class is "MyTest.class", by default, its url-pattern is "/MyTest"
So, to get access to this servlet, you must type on your browser
(Note: put the cursor over the text to see the entire text):

http://localhost:8080/servlets/MyTest

Assuming that your server is configured at 8080 port.
Hope this resolves your question.

Answer 2

Does your servlet container support "hot deployment" and do you have it configured to do such? If not, restart the web/servlet container.

Answer 3

May be the file name u specified might not be deployed in the correct location
