When you created the projects, you had to select a jboss server runtime, from which the classpath provider would get some classpath entries for compiling it. The ejb3.0 project is not a webtools project, but was created by jboss ide, which is why it required a jboss server to create. As a word of warning, ejb3.0 projects are under revision now to more accurately resemble webtools projects and work similarly, so they'll most likely be changing again before the next beta. Sorry for the inconveniences. I'll try to have a good conversion wizard available for them. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980491#...
