[jboss-dev-forums] [Design of EJB 3.0] - ejb-client-jar and manifest Class-Path

[alex.loubyansky@jboss.com]

Issue http://jira.jboss.com/jira/browse/EJBTHREE-862 and ejb3 core spec chapter 20.6 example.

I wrote a testcase based on the example in the spec. It fails to deploy. E.g. there is externalrefscoped-second.ear. It contains the ejb jar (called externalrefscoped-second-ejb.jar) and the jar with the client view interfaces of the ejb (called externalrefscoped-second-client-view.jar). The ejb jar doesn't include the client view interfaces but references the jar with them by the ejb-client-view element in the ejb-jar.xml and manifest.mf/Class-Path entry.

Here is the stack trace of the failed deployment

It seems like the manifest.mf/Class-Path is ignored here.
