Hi everyone
i've got some trouble packaging and deploying my application
At first i'm on jboss 4.2.0
my application is packaged as that :

appli.ear
lib/
external/
ejb.jar
appli.war
web-inf/
lib/


i isolated my application using classloader in jboss-app.xml.

i'd like to put all my dependencies under appli.ear/lib/external
but when i did it (i changed the classpath in all MANIFEST.mf) i got a classcastException with jaxb
the funny things is when i put all my libs under appli.ear/appli.war/web-inf/lib/ it worked

does anyone has an idea on the problem?
