Class Loader Problem...

[indyjones]

JBoss AS: 4.2.0
Seam: 2.0.0 BETA 1
Java: 1.6.0_02

I downloaded the most recent:

ajax4jsf-1.1.1.jar
richfaces-3.0.1.jar

Deleted my old ones and put these in WEB-INF/lib

I get the following error trying to use the HtmlDataTable class....

java.lang.NoClassDefFoundError: Lorg/richfaces/component/html/HtmlDataTable;

There have been some posts about this being a "Class Loader" problem...

How do I fix this?

Thanks

If exists many applications with richfaces do you need isolate it this with jboss.  Create the jboss-web.xml in web-inf folder.

See this link http://thorgull.be/doku.php?id=tutorials:jboss:classloaderisolation.
