Hi, env.setProperty(Context.SECURITY_PRINCIPAL, "system"); | env.setProperty(Context.SECURITY_CREDENTIALS, "..."); | env.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.security.jndi.JndiLoginInitialContextFactory"); does not work any more in JBoss 5 as far as I know. Use this: SecurityClient client = SecurityClientFactory.getSecurityClient(); | client.setSimple("user", "mypass"); | client.login() (see http://www.jboss.org/index.html?module=bb&op=viewtopic&t=144021, third post) Hope this helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4211414#...
