I have a simple mavenized project with a parent pom that manages an EJB, WAR and EAR module, which I hot-deploy (or publish) to a JBoss 7 server by dragging the EAR module to the server runtime. That part works.

However what I see is that the EAR and its child war module are deployed in exploded form while the EJB module (also a child of the EAR) is deployed in its packaged jar form. That means that the entire EJB module has to be published in stead of being able to hot-swap code through an incremental publish. Unless I'm very badly mistaken of course.

"Deploy projects as compressed archives" is OFF by the way.
