can't find file tad lib descriptor:"http://java.sun.com/jstl/core" ??
what i can do??

Do you have necessary lib files in classpath? jstl.jar, standard.jar etc.

Only jstl.jar and standard.jar are needed.. so no etc should be there...

Can you show us your web.xml file?

According to this http://dev-answers.blogspot.com/2006/12/according-to-tld-or-attribute.html, it looks like your servlet specification is wrong.

web.xml

Just saw your web.xml, you are using 2.4 version, please change it to 2.5, as shown below.

EDIT: JSTL-1.2 is supported from servlet 2.5 only, and the URI i gave refers to JSTL-1.2, you should not be using JSTL-1.1 at this point of time, especially, if you are developing newly.

Remove the goop from the web.xml -- it is not necessary and could just get in the way. All you need to do is to put the JSTL jar files in WEB-INF/lib.

And make sure that you do not have there servlet and JSP API jar files there. That's a common mistake that can screw up the classpath.

Avoid roseindia like the plague. It's a horrible site.

Pots your code here. Be sure to use code tags.

There is no need to declare taglibs in web.xml..
