Hello, I was trying to use the jboss embeddable alpha server in my unit tests. I downloaded the latest release and tried the tutorials and they ran fine. When trying to use the server with my tests i first got an java.lang.NoClassDefFoundError: javax/persistence/NoResultException Ok, so when looking in the ejb3-persistence.jar the class wasn't there and that must be a mistake. I added the ejb3-persistence.jar file from the jboss app server and then I got another of those NoClassDefFoundErrors: java.lang.NoClassDefFoundError: javax/persistence/spi/PersistenceInfo Maybe I'm missing something here but it looks like there are some errors with the embeddable release. /klejs View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3994758#...
