I have the same question.
Now I see that we have to restart JBoss to add new module (or change existing one). I also tried to find CLI for redeployment/refreshing of modules but can not find it.
Anyone knows if this is possible or we have to restart JBoss instance for changes to be picked up?
Modules can not managed with the server admin interface (CLI, web console ...).
I'm not sure, but the only posibility to reload a module is to stop all deployments which use this module, only in this case the module can be unloaded.
But therefore the modul version can be used, you add a new version of this module and deploy an updated application which depends aón that version.
