I am trying to access a jsp in a directory which is under the my web-app folder

My web-app folder is 'MyApp'.Under that i have made a folder named 'Dir'.
In 'Dir' i have a jsp page named 'First.jsp'.

When i forward the response to the jsp page throught the RequestDispatcher.

RequestDispatcher rd = request.getRequestDispatcher("/Dir/First.jsp");
rd.forward(request,response);

The url shows after this servlet forwards to the jsp is
http://localhost:8080/MyApp/Dir/servlet.do

The servlet.do is the serlet name in which the request dispatcher code is in,but i get a error page with 500 error code.

Please help me.

A code 500 error will occur when there is a problem with processing the page. It means that the page could be found otherwise you would have a 400 status code.

well, so you keep your jsps and java files under the same directory called Dir!... right? which is so ugly

no there are not in the same directory .....servlet files are in the 'classes/com/examples/web' directory and the jsp is in the Dir directory under the context root (accessible directly to the client if requested)

The error is 500, as mentioned in the original post.

As already pointed above the error is in the page processing.
Can you access the JSP directly ?

If you are getting an Error 500, then the server has encountered an "internal" error.

The easiest way to identify the cause is to find the server log file, and look at what exception was thrown!

Assuming you are using TomCat on a local machine then by default the exception will be written to localhost.yyyy-mm-dd.log in your logs sub-directory. Where yyyy-mm-dd is the current date, and the logs sub-directory is usually under the parent tomcat install directory.

For neatness it is sometimes best to stop tomcat, delete ALL the log files, start tomcat then open the URL that is causing the error.

If you need any help diagnosing the error then post the exception details from the log file.

Rufus.

Sorry. I understood that the error is 500, but I mean what is the exception log, but you already asked that and explained how to find it.

i do not know this would help you or not. Try starting the tomcat using the batch files in the bin dir, this way there will be a command window displaying all the details and logs going on in the tomcat. And you can use the system.out.println statement to check/hint where you are going wrong. And for the tomcat to work i.e. to start properly by using the batch file you must first set all the environment variables set correctly.
