Have you checked the JSP FAQ? It will likely answer most of your questions?

[srinivas.b]

I checked my web.xml , everything fine. still i am getting same problem

anyone can solve please

[Bear Bibeault]

What did you check in your web.xml? Where did you put the JSTL files? How are you referencing the taglibs on the pages? Which version of JSP? Which version of JSTL?

We can't help if you don't give us any information.

i checked JSPFAQ and the provided instructions to check spec for jsp2.0 servlet2.4 ...actually i dont have a better idea on these as i am a beginner.
but i would like to learn.can you please explain me. My IDE is saying some internal error. like this:

HTTP Status 500 -

type Exception report

message

Can you post the contents of your web.xml file?

Also, let us know about your web app.
How did you create it?
What directory is it in?
Post the contents of your JSP too.
