    Seam-gen

    Tony Tony Newbie

      Hi All,

      I read the tutorial on seam reference documentation. But I can't run the simple war file which is genereated from seam-gen code (when I execute the seam new-project).

      here are the error and any helps will be appriacited:

          As far as I know, Seam Gen only supports EJB3, doesn't it? So: has JBoss been setup for EJB3, or are you using 4.2.RC1 or RC2?

            Hi,

            I am using JbossAS 4.2GA. I am not too sure about Jboss seam only support ejb3. if this is the case, then i shouldn't use it because i'll use hibernate.

            if not, can you or anyone else confirm that what do i miss/need to do?

            Cheers,

            -T

              Seam 1.2.x apps won't work on 4.2.0 GA without some minor tweeks.
              Check Michael Yuan's post on his blog: http://www.michaelyuan.com/blog/2007/05/29/seam-book-examples-updated-to-jboss-as-420-ga/

                you must get jboss seam from CVS and after all works fine for jboss 4.2.0GA.

                  You can surely use Hibernate along with EJB3; all Seam examples use it too.

                  If the Seam Gen generated project gives you an EAR then I think you'll need to deploy that (and not just the WAR file that you might find within that EAR).

                  Alternatively, you'll need to tell Seam Gen to generate a WAR-only project -- if it can do that (searching for "embedded EJB3 might help you to find the answer; but using EJB3 might be easier).

                  Your Could not create Component: org.jboss.seam.core.init without any further details will not be enough for people to tell you what's wrong.
