Looks like the parameters that you passing as JVM params are not reaching the client. Try this: private UsuariosRemote lookupUsuariosBean() { | Context iniCtx; | try { | Map env = null; | Set propertiesSet = null; | Iterator it = null; | | iniCtx = new InitialContext(); | | System.out.println("************** System Properties ****************"); | Properties props = System.getProperties(); | props.list(System.out); | System.out.println("************** System Properties ****************"); | ..................... | What does this output?
