    Alex Cougarman Apprentice

      I'm trying to get the Registration example working and it's throwing this exception. Help!

          The following msg:


          message: "/register.xhtml @17,84 value="#{user.username}": Target Unreachable, identifier 'user' resolved to null"



          indicates that the 'user' Seam component has not been registered/instantiated by the Seam container when you deployed your application.


          in your server.log or console, look for the following section:


          13:37:07,168 INFO  [Initialization] Installing components...
          13:37:07,215 INFO  [Component] Component: applicationMetaData, scope: SESSION, type: STATEFUL_SESSION_BEAN, class: com.cox.bets.session.ApplicationMetaDataAction, JNDI: BETS/ApplicationMetaDataAction/local
          13:37:07,293 INFO  [Component] Component: arbiTestView, scope: CONVERSATION, type: ENTITY_BEAN, class: com.cox.bets.entity.ArbiTestView
          


          and see if Component: user, ... shows up.


          if not, you need to figure out if there is a @Name(user) annotation in your classes or not and determine whether or not Seam container is instantiating this component or not...

            @the original poster: what version of Seam and JBoss and how are you building/deploying the app?
