... ok, I see possible workaround for my question ...
... On eclipse server dialog exist some settings that can help to combine automatic eclipse publishing (important for hot deploying) with allready started externally managed server.
... hm ... state of this server in eclipse servers is now stopped, but it do not really republish (no hotdeployed) changed resources
... trying with server starting in eclipse (fake, because settings assume that server is allready started)
... YES ... It's work ... each changed resources are autopublished to server and hotdeployed
Anyway, thanks people
Yes ... I have allready installed this plugin ... But clue was to start external managed jboss (on command line) AND to (fake) start in eclipse (change default settings not forget!). Thanks
