    MalformedURLException for cache config in a web app

    Bob Ninja Newbie

      I have a simple web app that tries to initialize and use a cache instance. I am running the latest AS BETA 4, using the ALL config that includes cache lib.

      I copied one of the sample config files:
      all/lib/jbosscache.jar/META-INF/replSync-service.xml
      ... into my app to avoid any issues. My code is simple:

      // read configuration
      final XmlConfigurationParser parser = new XmlConfigurationParser();
      final Configuration config =
      parser.parseStream(CacheContext.class.getResourceAsStream(conf_path));
      // init cache
      CacheFactory<String,Object> factory =
      new DefaultCacheFactory<String,Object>();
      cache = factory.createCache(config, true);

      I have my own context class co-located with the config file. The server is generating this:

      Looks like it does locate the file fine and starts reading it, but then fails due to a URL. "getDocumentRoot" seems to imply an early failure at the start of the file. "determineDocVersion" might imply processing the 1st tag,
      <?xml version="1.0" encoding="UTF-8"?>

      Not sure. I don't really see any URLs there. In any case I only changed the cluster name, so this is the stock config file that same with AS. I would assume that it should parse fine.

      Tried searching old posts, but found not clue. If there is another existing resource that explains this sort of issue, I would appreciate a tip.
      Or just in general any tip, as what area I should focus on.

      thanks
