.tld from jar in default/lib not read?

[henk53]

In an EAR application normally deployed to JBoss AS 5.1 I have an oscache jar in /server/default/lib. It was necessary to put it there, since the application is using class loader isolation (loader repository in jboss-app.xml) and os cache is used as cache for Hibernate. When it shipped in the EAR, Hibernate couldn't find it.

The oscache .jar also contains a .tld that's used by the web module in the EAR.

When I move this application to JBoss AS 6, I got the following exception when loading a page that references the namespace from the os cache .jar:

org.apache.jasper.JasperException: The absolute uri: http://www.opensymphony.com/oscache cannot be resolved in either web.xml or the jar files deployed with this application

Is there any way I can resolve this? For the time being I would like the app to be compatible with both JBoss AS 5.1 and JBoss AS 6.

Never mind this question. There were a couple of other errors relating to differences between JBoss AS 5 and JBoss AS 6.

For some reason however those errors where not shown in the log while starting, and the web module was started even though it actually shouldn't have. I did a couple of things and then after a restart those errors were shown and the web module (rightfully) wasn't started.

It's a bit hard to trace back what exactly happened, so just forget about this one. It maybe was collateral damage.
