I have created a simple Java EE 6 Enterprise App using the latest ICEfaces NetBeans IDE integration.
When I deploy my ear archive to Glassfish v3, I get the following error:

SEVERE: Exception while invoking class com.sun.enterprise.web.WebApplication start method
 java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.NoClassDefFoundError: org/icefaces/context/DOMPartialViewContext

After having a look at the ear archive, it turns out that the icefaces-comps-compat.jar and icefaces.jar are not included in the EARs lib folder. Instead, they are included in the WARs WEB-INF/lib folder. The other required jars (icefaces-compat.jar, icepush.jar) are correctly packaged in the EARs lib folder.
