Individual jsp in exploded ear/war == yes.
Individual session bean == no
Where can I find documentation on How to for expanded directory deployment(for development time) on JBoss?
There is much to it: you can unzip any packed archive (.jar, .war, .ear, .sar, etc.) to a directory that has the exact same name (e.g. my.sar -> my.sar/).
Redeployment then, instead of happening whenever the archive was 'touched', happens whenever the main descriptor is touched (e.g. for my.sar, would be my.sar/META-INF/jboss-service.xml)
To be certain what gets 'watched' for each deployment, there is a method getWatchURL() (if I remember) on jboss.system:service=MainDeployer.
Its an old thread but I wanted to ask maybe there is a new solution.
is there any supported way to update a single compiled JSP in a existing EAR depolyment?
maybe mbean that loads the file or take it from file location and zip it in the right place in an ear or a war?
No, unless the whole .ear stucture is unzipped.
