Precompiling all the JSPs with Tomcat

[Ashish Agrawal]

Hello,
How can I precompile ALL the JSP files in tomcat 4.0 on start-up? Is there any way using web.xml?

Thanks,
Ashish Agrawal.

To be more specific.....

Does anybody know how to precompile all the jsp files on or before startup of tomcat 4.0?

Like .... maybe using jspc.bat....but it just translates the jsp to .java....but doesn't compile. Each jsp gets compiled only on first http request.

Is there any way to do this using ANT?

Please reply ASAP. Thanks.
