I have some difficulty with the dozer class loader running in in EAR app in Apache Geronimo 2.2.1. I modified the classloader to println() the class name it was trying to load when it gets a CNF.
Strangely org.dozer.util.DefaultClassloader is trying to load an instance of org.dozer.util.DefaultClassloader and fails. For some reason this class tries to load itself and fails with a CNF. Underneath it uses the Apache commons lang class loader. Initially I thought it may be a problem with that so I upgraded to commons lang to 2.6 (the latest… I was running on 2.3). Anyway I think it is something else. It was also having problems finding my dozer.properties and xml config etc. when it is clearly in the classpath of the EAR app. Also I can run it from a main() with my XML config and it is fine. We have a huge structure to parse and I did most of the mapping work already so I really want this functional.
I even went as far as stuffing the dozer.properies file and my dozerBeanMapping.xml into a copy of dozer-5.3.2.jar and deploying it as a Geronimo dependency like so:
This way it definitely finds the properties file and the XML config but still CNF's like this:
