1) You should not construct a Cache Loader explicitly. When you start the cache, a cache loader is created and configured for you based on your configuration file. 2) Your configureCache() method is unnecessary. 3) Your getConfigFile() method should return the name of an XML file (as a String) which needs to be in your classpath.
