Forget about it, I have sucessfully deployed JBOSS 5.0.0 GA with this configuration - I guess JBOSS 6.0 Final is not so final then!!
Appreciate the feedback.
To answer your original question, yes, the tiered architecture described above is achievable. As for your bullet points:
- While you can certainly use mox_proxy with JBoss AS, we recommend using mod_cluster instead. JBoss AS6 includes built-in support for mod_cluster. Details here: http://jboss.org/mod_cluster
- Creating JBoss cluster partitions is as simple as starting the server using the all profile. You can group servers into logical partitions via the "-g" command line argument to the run.sh script. Execute "run.sh -h" for details.
- Connecting JBoss AS to MySQL cluster is no more complicated than connecting to a single MySQL database. http://docs.jboss.org/jbossas/getting_started/v5/html/db.html#d0e1998
Now, regarding your followup post - what seems to be the problem? If you were able to deploy fine to 5.0, what's preventing you from deploying to 6.0?
