Why do I get an AbstractMethodError when setting a JSTL variable?

Question

I am trying to set a variable that I will refer to in a custom JSP tag, so I have something like this in my JSP:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="path" value="test"/>

However, I am getting this error when The JSP runs:

java.lang.AbstractMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;
    at org.apache.taglibs.standard.tag.common.core.SetSupport.doEndTag(SetSupport.java:140)

I am running Tomcat 5.5, and Java 1.5, with JSTL 1.2.

Am I doing something wrong here?

Thanks!

Answer 1

Looks like you may have some versioning problem, maybe a conflicting jar file of some sort. Look here, maybe it'll help. You need to supply some more info about your runtime environment if you can't solve it.

Answer 2

i am also facing the same problem. my c:foreach is not working, the same exception is being thrown. whilw c:out and c:set etc are working properly

Answer 3

Tomcat 5.5 does not support Servlet API 2.5 which is used by JSTL 1.2.

Upgrade to Tomcat 6.0 or downgrade the Servlet / JSP / JSTL versions.

see http://tomcat.apache.org/whichversion.html
