I get NoClassDefFoundError when I attempt to start up a JBoss service packaged into an EAR file. There is no WAR file in this application as there is no web interface. I get this error even if I put my JAR file into the server/default/lib directory. Yes, the JAR does indeed contain the .class file JBoss says no definition exists.
I did this:
* created a JBoss service
* I packaged all the Java class files into a JAR file
* I put this JAR file into the EAR file's lib/ directory
* The ear has a manifest Class-Path entry pointing to the jar
* I added a jboss-app.xml file to the EAR file (below)
* I added an application.xml file to the EAR file (below)
* I created a SAR file that contains the same manifest entry
* In the SAR file I added a jboss-service.xml file (below)
* I put the SAR file in the EAR file
