anonymous wrote : khanrahan I was having this same issue until I discovered that one of my third party jars was corrupt. When I would make a request that included a custom tag in the response (the first time the custom tag was accessed) all of my jars were being searched/scanned until the tag library was found. khanrahan - your post was EXACTLY what I needed to fix this problem that plagued me. I did a jar xvf commons-collections-3.2.jar and it revealed an error with that jar that somehow crept in. THANK YOU from MN!
