When you create an Seam 2 ear project in JBDS with Seam 2 trunk you get

1) A runtime exception from drools asking you to put JDT core on the classpath. WORKAROUND: copy core.jar from seam/lib to the test project/lib directory, and add it to the test project's build path

2) An exception from Seam complaining about missing security.drl. WORKAROUND: move security.drl from the ear project/EarContent to the ejb project/ejbModule
