JBoss development, A new message was posted in the thread "Structure deployer cannot access manifest": http://community.jboss.org/message/529914#529914 Author : Ales Justin Profile : http://community.jboss.org/people/alesj Message: -------------------------------------------------------------- Most likely -- see HERE.       public static Manifest getManifest(VirtualFile archive) throws IOException {         if (archive == null)             throw new IllegalArgumentException("Null archive");         VirtualFile manifest = archive.getChild(JarFile.MANIFEST_NAME);         if (manifest == null || !manifest.exists()) { // HERE -- manifest.exists() == false             if (log.isTraceEnabled())                 log.trace("Can't find manifest for " + archive.getPathName());             return null;         }         return readManifest(manifest);     }   You need an explicit mount -- like explained eariler: http://community.jboss.org/message/529846#529846   It will a bit tricker here, since you wanna use your VFS abstraction. Meaning your abstraction will have to know wheather it needs to mount or not. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529914#529914
