Care to share what solved your problem ?
I didn't get around answering you before but my answer would have been to upgrade to the final versions of JBDS 4 and JBoss 6 instead of using old milestones.
Problem not fully solved...but found the old way to see the changes i do in my JSPs. Extracted the WAR and made the changes in the server only.
For the class files i restarting anyway.
Using JBDS.. doesnt help...
Plz do let me know if you find any way to do this with JBDS (Jboss Dev Studio).
How about trying out the final versions of JBDS and JBoss AS 6 first ?
