Looks good from a first glance :)
What are your plans for the plugin?
this looks interesting! :)
I've just started working on this Jira : http://jira.jboss.com/jira/browse/JBESB-1365, which deals with eclipse plugin(s) for JBoss ESB.
The idea is to pull out the functionality from the config editor and perhaps add additional features.
What's currently in the esb project is a wizard to create a template project in eclipse.
I'd be interested in hearing if you have similar plans for your plugin? Perhaps we could join forces?
Would you be interested in contributing this code to the JBossESB project?
