    No injection on my session bean

    yachaa Newbie

      Hi there,

      I got the following problem on my Seam application. Looking at the error, it seems my properties are not injected by Seam. Thanks beforehand for your help.

      The application is to register new user before enabling the user to login to the system.

      When clicking "register" on the registration page, debug page appear with the following:

      Exception during request processing: javax.servlet.ServletException: /registerUser.xhtml @26,72 value="#{registerUser.verify}": Exception getting value of property verify of base of type : org.javassist.tmp.java.lang.Object_$$_javassist_5

      Looking at the error, it appear to me that there is either EL exception or injection error (no idea why though....) This seems to happen only in session bean...

      I have done the following as well to come up with the above conclusion:
      I use seam-gen and tried the authentication (as a managed bean) and the login working properly. But when I migrate the authentication to session bean, it does not work properly and I got the same error as above.

      Any help and idea is appreciated.

      Cheers.
