Java EE (Java Enterprise Edition) General Discussion

My application contains classes generated by Jaxb-1.0-beta apart from other classes. I am using jaxb generated code to marshal/unmarshall xml data files. Everything works fine as long as i am working in development envt with package structure present as folders in my classpath.

But things go for a toss when i package this application into a .jar file and use the jar file instead of expanded folders. The JAXBContext.getInstance() complains that it is not able to find the 'jaxb.properties' file. please see the trace below,

----------------------
javax.xml.bind.JAXBException: Unable to locate jaxb.properties for package com.hps.haf.jaxb.errorhandler
at javax.xml.bind.ContextFinder.searchcontextPath(ContextFinder.java:176)

--------------------------------

I even tried putting a file named "javax.xml.bind.context.factory" in meta-inf/services directory. But this does not seem to help.

Can anyone help please? Thanks in advance.
cheers
