TridentConfig.java should not use Thread.currentThread().getContextClassLoader() its not granted that this classloader is set in all environments. i think, getClass().getClassLoader().getResources() should be used instead. ---------- ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); Enumeration urls = classLoader.getResources("META-INF/filename.properties"); while (urls.hasMoreElements()) { URL pluginUrl = (URL) urls.nextElement(); ... } --------- for reference see: http://www.javaworld.com/javaworld/javaqa/2003-06/01-qa-0606-load.html regards, andre
