What we should do now is differentiate between this: 1) exploded inner dir containing persistence.xml 2) nested jar containing persistence.xml For 1) we strip the vfs prefix off, for 2) we return VFS URL, which will lead to VFSURLConnection --> VirtualFile.openStream --> ZipInputStream. I can add some VFSUtils.isNestedJar method which knows how diff between 1) and 2) based on the handler impl. OK?
