Question

I have a jboss application with some ears. There’s war inside ear and there’s file monitor.tld inside WEB-INF folder of war.

There’s some tag definitions inside the monitor.tld. I added my custom tag definition in this file, and restarted jsboss. After that, when I use my tag in jsp I get error:

So, my custom tag wizardNavEx doesn’t work, but wizardNav defined in monitor.tld a couple of lines above works fine.

I think the problem is tomcat/jboss cached previous version of monitor.tld in someplace. How can I clear that caches? Any ideas?

Versions:

X-Powered-By=’Servlet 2.4; JBoss-4.2.2.GA (build: SVNTag=JBoss_4_2_2_GA date=200710221139)/Tomcat-5.5′

Answer 1

The problem was that another monitor.tld existed inside one of jar files.
