Very easily I'm afraid. The call stack is unrelated to the classloading
mechanism. I am also unable to see the same class appearing in the call
stack - it complains it is missing
com.pentaho.repository.subscribe.SubscriptionHibernateHandler whereas the
class in your call stack is
com.pentaho.repository.subscribe.SubscriptionRepository.
That said, it does look like Pentaho is invoking the webapp classloader to
load the class. Are you absolutely sure the relevant jar files are in your
WEB-INF/lib directory? And have you tried a different container, e.g.
Tomcat? It may just work ;-).

Hi Matt et al,
I have a strange class loading problem when running with mvn jetty. The
webapplication framework is based on appfuse and I am trying to get
another
standalone application running in it. Please ignore for now that
application. The strange problem is that jetty webappclassloader is not
able
to find the class
"com.pentaho.repository.subscribe.SubscriptionHibernateHandler" whereas
the
same class is what has already been invoked at the bottom of the stack (
look below for the bolded line). I know this can be pushed off as a
Pentaho
problem. But all I am asking is how is it the same class got invoked at
one
point in the stack and later on up the stack a different classloader is
not
able to find the same class. Any ideas would be greatly appreciated!!
Thanks for your help.
