[jboss-user] [Installation, Configuration & DEPLOYMENT] - Classloading issue moving from 4.2.0 to 5.0.1
I have an application which is running without issue on JBoss 4.2.0. I am attempting to
run the same application on JBoss 5.0.1 and I am hitting a classloading issue. It happens
during deployment while Spring is instantiating my Spring managed beans. The class which
cannot be found is in the Facelets library and the bean being instantiated is one of mine.
The Spring jar, the Facelets jar and the jar containing my class are all packaged at the
root of the EAR and referenced by the WAR via the MANIFEST.MF. As I said before, this
worked fine in 4.2.0.
FWIW, I am using the standard configuration for JBoss (although I get the same results
using the default configuration) on Windows 2000 SP4 with JDK 1.6.0_01.
Here is the relevant portion of the error:
Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate
bean class [com.mycompany.faces.FaceletViewRendererImpl]: Constructor threw exception;

I did look over the release notes and documentation and found nothing to indicate a
classloader change which would affect this (as far as I could tell anyway). I also tried
the suggestions at http://www.jboss.org/community/wiki/ClassLoadingConfiguration to no
avail.
I'd appreciate any suggestions as to how to resolve this.
