The good news is that the Seam plugin for Netbeans deploys without any issues to JBoss 4.0.5 server. I've also added a Postgresql database into the mix and successfully generated entity classes and deployed to 4.0.5 successfully!
The bad news is that I ran into an issue with M9. At least, it is an issue with M9 and the Facelets plugin (on my workstation). I cannot tell if this issue is a bug with M9, or just my slow workstation, but the IDE literally locks up if I try to edit XHTML files with the Facelets plugin installed. I just found this out this morning when trying to add a new Facelets page to my Seam Plugin app. It would not work...I restarted the M9 application several times.
Needless to say, I've reverted to Netbeans 5.5.1 and have been using the Facelets code without issue.
In summary: Netbeans 5.5.1, Seam Framework Plugin, Facelets Plugin, and Postgresql database create an easy CRUD application without issue...and in just a few minutes!
As stated in previous posts, I will try to make a mini-application using this model. I then wish to port it to Glassfish as well just to see how difficult that step will be. It may take me a while...but I will post my results.
