Hello,

When I add a simple <c:set var="foo" value="bar"/> line to my jsp I get the following error:

javax.servlet.ServletException: javax/el/ELException
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:273)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

I'm developing in Eclipse using Tomcat 5.5.28. I've got the latest JSTL jars from GlassFish. Looking through these jars and all the rest of the jars in my my project I don't see the offending class (or even a 'javax/el' package). Am I missing a jar somewhere?

Any help appreciated.

Regards,

Bill

Actually, I take back part of what I said. Looking more closely at the jars in my project there is a jsp-api.jar that contains the class:

javax.servlet.jsp.el.ELException

It appears that this jar came from my Tomcat 5.5.28 installation from the 'common/lib' directory and was copied into my project when I created my Eclipse project as a Tomcat project (using the sysdeo Tomcat plugin).

So it would appear that something is looking for ELException in the wrong package? Any ideas what/why/how to fix it?

thanks in advance,

Bill

The problem seems to be that I was using JSTL jars that I downloaded from:

https://jstl.dev.java.net/download.html

These appear to be version 1.2. For whatever reason, they do not appear to be compatible w/ the jsp-api.jar that comes with Tomcat 5.5.28.

When I went back to version 1.1.2 from:

http://jakarta.apache.org/site/downloads/downloads_taglibs-standard.cgi

Things started working.

regards,

Bill
