JSTL installation

Hi Ranchers
I'm trying to install JSTL and have downloaded JSTL 1.1.2 version binaries. I have placed the jar files of the same in the lib folder of Tomcat @ C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib. I have also placed the tld files in WEB-INF folder @ C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\ROOT\WEB-INF. Is this the right path where these files should be placed? And do I also need to update the web.xml with the tlds?

My Tomcat version is 6.0 but am not sure what my Servlet and JSP versions are. Where/how can I come to know their versions?

Remove the TLD files. Why did you extract them from the jar files? The container will find the TLD files inside the jars.

No TLD declarations in the deployment descriptor are necessary.

This is all covered in the JSP FAQ.

Hi Bear
I have not extracted the tld files from the jar files. There was a folder called tld and I placed all the files in that folder. I have read it somewhere that we need to place the tld files in WEB-INF folder. Anyways I have removed them now. But the problem now is am getting an error on the browser, so I doubt if I had actually installed JSTL properly or not.

Here's the program and the error that's displayed on the browser.

And the error:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.
