Business interfaces can be implemented by multiple beans, so there must be a clarifier in between. + "ejb/" + vfsPath + local-interface name + "/" + ejbName should work. If we then get a non-deterministic injection we can throw an exception. Why not reverse it a bit: + "ejb/" + local-interface name + vfsPath + "/" + ejbName then traversal is a bit easier in case multiple jars within one ear contain the same interface.
