Hi,
I have an application that works fine on JBoss when
the jar files are deployed separately but throws a NoClassDefFoundError when they are deployed in a .ear
file together. I studied the FAQ about this topic and I know
the Class-Path manifest header but I was not able to
solve my problem. I describe the content of my ear
file and the references between them.
application.ear
framework.jar
(EJB Module, contains the remove interfaces too).
Class-Path: plugin1.jar plugin2.jar framework.jar
plugin1.jar
(Utility classes)
Class-Path: business-logic.jar
plugin2.jar
(Utility classes)
Class-Path: business-logic.jar
business-logic.jar
(Utility classes)
Class-Path: framework.jar
As you can see there are circular references between the jar files (i.e framework.jar - plugin1.jar - business-logic.jar - framework.jar). I suspect this could be the cause of the problem. Even an EJB module participates in a circle. Does the J2EE standard allow
such circular references between the jar files in an ear
file?
