Hi All, We have developed an developed using Seam 1.2.1 GA and Facelets. It deploys properly and functions as desired when deployed within JBoss 4.0.5 For Prod we need to deploy it on WAS 6.1.0.13 and it gives an error saying "Could not start transaction". It will be great if anybody could provide a heads up (direction) for going forward.... Please find stack trace attached.
