Using JSTL 1.0 on WebLogic 8.1

Question

Hi,
I'm just starting out to learn how to use JSP Tag Libraries and JSTL 1.0. I tried to deploy the examples on Weblogic 8.1SP3 and it works ok. But when I tried to use the tag libraries in my own application, I got this error:
Error 500--Internal Server Error
java.lang.NoClassDefFoundError: javax/servlet/jsp/el/VariableResolver
Here's what I did to deploy the tag libraries
1. Copy the standard.jar and jstl.jar into my WEB-INF/lib directory.
2. Copy the c.tld into my WEB-INF\tld directory.
3. Edit my web.xml to add this entry
<taglib>
     <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
     <taglib-location>WEB-INF/tld/c.tld</taglib-location>
</taglib>
4. In my JSP, import the tag-library with this directive
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
Any ideas what I might have missed here? Thanks!

WARNING! WARNING! DANGER WILL ROBINSON!
The URI you mentioned: http://java.sun.com/jsp/jstl/core is for JSTL 1.1
This requires a JSP2.0 container (eg Tomcat 5)
Weblogic 8.1 is still only 1.2 compliant.
You need JSTL 1.0 for that.
You import it with the tag <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %> (not the difference - this one does not have "jsp" in it)
Seems like WebLogic is missing the jsp-api.jar that Tomcat installation has.
I copied the JAR over into the WEB-INF for my application Bad move IMO. If you have the correct version of standard.jar and JSTL .jar you shouldn't need anything else.
Make sure you have the version that is standard1-0
Another note on installation:
All you need are the jar files in web-inf/lib.
No tlds lying around
No entries in web.xml
The tld file is hidden inside standard.jar. The webapp will find it automatically if you use the correct URI.
