Hi all, We're having abit of trouble with jarfile-versions, since certain parts of our application need one version of a jar and other parts another version. Our system uses version 2 of foo.jar but the classes used to communicate with an external billing-system are not compatible with version 2 and have to use version 1 of foo.jar. Is it possible to specify that the classes in billing.jar should use a certain version of foo.jar and the rest of the system another. Everyhing is packaged and deployed in one .ear-file. Would appriciate any tip or hint on how to solve this problem! Cheers Johan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965015#...
