Look at your error logs again. Is that the full error message that you got?

there is no error logs my file

You are running this on tomcat or Jboss or some web container or application server. That server has a log file that it starts when you deploy your application. It uses it to log things about your application including full exception stack traces if an exception propagates to it. Find out where that log file is and check it. You will need it for future errors anyway.

i using the tomcat server with help of eclipse . i am searched tomcat but not there in tomcat ..

Eclipse should have been showing you the errors. Anyway, in your eclipse, go to the servers view and right click the server you have added there (the Tomcat), chose open to see the server definition in eclipse.
Then look for the "Server path" entry in the properties for the server. Your log files should be in a subfolder of that path.

Make sure this action forwards to the JSP, and then call the URL for the action (/myaction.do) rather than calling the JSP directly (/mypage.jsp).
