[opencms-dev] Strange Error with Opencms Taglib

[Alexander Langer]

On some of my JSPs I get a system error. I don't understand why and
why I don't get it out of every JSP. Can someone explain this?
The line

<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

is the same in every of my JSPs.

The message:

javax.servlet.ServletException: Resource loader error in file '/karriereberatung-methodik.jsp'

Root cause:
org.apache.jasper.JasperException: This absolute uri (http://www.opencms.org/taglib/cms) cannot be resolved in either web.xml or the jar files deployed with this application
