In the above messages I used the webstart installer and selected All and used all the defaults. I just punted on that. I deleted the jboss directory. I installed the latest jdk 1.5.0_09 and downloaded the jems installer from sourceforge - jems-installer-1.2.0.BETA3.jar On installation I selected EJB3 not All. Now I don't get the BSOD. (it is unclear to me that if you select All if you get EJB 2.1 or 3. I was assuming 2.1) This wasted a lot of my time.
