Oops, sorry about the bad reply.

As Bear Bibeault said, do not extract c.tld
It is already in standard.jar.
So just put standard.jar and jstl.jar in your lib directory.

Actually, do not extract the tld file and put it anywhere. You should put the jar files for the JSTL (there are two: standard.jar and jstl.jar) in WEB-INF/lib.

Be sure that you download and use the correct version of JSTL for your container. For Tomcat 4 you should be using JSTL 1.0. However, your message indicates that you are using JSTL 1.1 which should only be used with Tomcat 5.

The JSP FAQ has an entry with more infor on downloads and URIs for the appropriate versions.

dear friends,
i followed the instruction given below. but now the error message added at the end of the message.
1. Download JSTL distribution file at http://jakarta.apache.org/site/downloads/downloads_taglibs-standard.cgi

2. Unzip the distribution file.

3. Copy the following 2 files to your project's WEB-INF/lib/ folder:

jstl.jar
standard.jar
4. Copy all JSTL TLD files your project's WEB-INF/ folder:

5. Modify your project's web.xml file to include the TLD files. Add a <taglib> directive inside the main <web-app> directive for each of the tag libraries that you want to use. Here are the list of entries that might be added:

<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>;
<taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt-rt</taglib-uri>;
<taglib-location>/WEB-INF/fmt-1_0-rt.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>;
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/core-rt</taglib-uri>;
<taglib-location>/WEB-INF/c-1_0-rt.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>;
<taglib-location>/WEB-INF/sql.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/sql-rt</taglib-uri>;
<taglib-location>/WEB-INF/sql-1_0-rt.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/x</taglib-uri>;
<taglib-location>/WEB-INF/x.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>http://java.sun.com/jstl/x-rt</taglib-uri>;
<taglib-location>/WEB-INF/x-1_0-rt.tld</taglib-location>
</taglib>

6. You are now ready to taglibs in your JSP pages. Use the <%@ taglib %> directive to include the tag library that you want to use in your JSP pages. For example, to use the core tab library, add the following line at the beginning of your JSP pages:

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

7. Build your project. If you use Eclipse, you might have to refresh your project before building it so that Eclipse will pick up all the new JAR and TLD files that we've just added in. If you use ant, make sure you have the following 2 files in your classpath:

standard.jar
jstl.jar
