[jboss-user] [JNDI and Naming] - ClassNotFoundException on Context.lookup() after login with custom Principal

Ozan Ayyüce [https://community.jboss.org/people/ozay] created the discussion "ClassNotFoundException on Context.lookup() after login with custom Principal" To view the discussion, visit: https://community.jboss.org/message/647666#647666 -------------------------------------------------------------- Hi, we have a client-server-setup and are migrating to AS 6.1.0. Unfortunately, a JNDI lookup fails with a ClassNotFoundException as root cause. Previously, we had extended SimplePrincipal to add some fields. In our client, we use the LoginContext with a custom password handler to authenticate at the AS. handler = new CustomUserPasswordHandler(user, pwd, mandatorID);   final LoginContext loginContext = new LoginContext(LOGIN_CONFIGURATION, handler);   try {     loginContext.login(); } catch (final LoginException ex) {     throw new IllegalStateException("Could not initialize clients login module: " + ex); }   the client auth.conf specifies a custom login module: client-login {         de.xxx.xxx.secure.CustomClientLoginModule required     ;     org.jboss.security.ClientLoginModule  required     password-stacking="useFirstPass"     ; }; Our custom login module creates our custom Principal: @Override public boolean login() throws LoginException {     loginFailed = true;       getUserInfo();       loginPrincipal = new CustomPrincipal(mandator, customAttr, username);       sharedState.put("javax.security.auth.login.name", loginPrincipal);     sharedState.put("javax.security.auth.login.password", loginCredential);       loginFailed = false;     return true; }   After login, any call to Context.lookup() results in a ServiceUnavailableException:      theNewsTopic = (Topic) ctx.lookup(Names.JMS_TOPIC_UPDATE_USER) javax.naming.ServiceUnavailableException: Unexpected failure [Root exception is

de.xxx.xxx.secure.CustomPrincipal]     LOG.error("Your log-message: ", e); } Needless to say, CustomPrincipal is in the classpath, and is created once when the login call is made. Any advice would be very helpful as we are out of ideas on how to narrow the error down. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/647666#647666] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
