Sure, this is a valid setup; shouldn't be any consequences unless you eventually specify that one module depends on another, in which case you'll get errors unless they're deployed together at the same time. Also, EAR packaging will allow you to change up the classloading configuration, as you may run into issues down the road depending upon how your classes are being shared within your applications: http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration But again, packaging is a choice that should be made based on what'll work best for you. For smaller apps I like to deploy simple JAR (or .ejb3, as you're using) archives. I like greater control over my enterprise applications at work, and those get thrown into EARs as part of the build.
