    Trouble creating user on the fly programatically

    David Hoffman Newbie

      Using: jboss-portal-2.6-BETA1-bundled, configured to use MySQL as the datastore

      I have a custom auth module that authenticates a user against Active Directory Server and drops a user into roles that are derived from ADS attributes.

      Upon successful authentication, as long as a user exists in the jbp_users table, I am able to log in successfully.

      However, if the user does not already exist in the jbp_users table, the following error occurs:

      HTTP Status 500 -
      
      --------------------------------------------------------------------------------

      I have made the following attempt to create the user on the fly:

       try {
       UserModule userModule = (UserModule) new InitialContext().lookup("java:portal/UserModule");
       User user = null;
       try{
       user = userModule.findUserByUserName("username");
       } catch (IdentityException nsue) {
       //User Does Not Exist, so we need to create
       try {
       user = userModule.createUser("username", "password");
       } catch (IdentityException ie) {
       //This should not happen
       log.error("Error creating user", ie);
       }
       }
      
       try {
       UserProfileModule userProfileModule = (UserProfileModule) new InitialContext().lookup("java:portal/UserProfileModule");
       userProfileModule.setProperty(user, User.INFO_USER_EMAIL_REAL, new StringBuffer("username").append("@email.com"));
       userProfileModule.setProperty(user, User.INFO_USER_ENABLED, true);
       userProfileModule.setProperty(user, User.INFO_USER_VIEW_EMAIL_VIEW_REAL, true);
       userProfileModule.setProperty(user, User.INFO_USER_NAME_FAMILY, lastName);
       userProfileModule.setProperty(user, User.INFO_USER_NAME_GIVEN, firstName);
       } catch (IdentityException ie) {
       log.error("Unable to update identity.", ie);
       }
      
       } catch (NamingException e) {
       log.error("Error in Create UserModule", e);
       }
      
      


      When I execute this code, the following exception is thrown in the logs:

      It looks as if there might be some sort of configuration issue, or perhaps some preperatory coding, that I have missed because the error message states that it is "Caused by: org.hibernate.HibernateException: Unable to locate current JTA transaction"

      If there is any additional information required to help resolve this issue, please let me know and I will attach it to this thread.

      Thank you in advance for any assistance in this matter.
