Was: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=104577 Hello there! I'm setting up a JBoss ejb3 project. I have my SLSBs and Entities deployed to my JBoss instance, and I'm testing it from my project inside the JBoss IDE. Everything was working just fine. So I've created a second project, and put my tests there! I've added the myproject-client.jar (contains interfaces and entities) to the classpath, and when I run the same test now I get a: Caused by: java.lang.ClassNotFoundException: [Lcom.acme.model.persistence.Product; It seems that the client is not being able to check the jar loaded with the classes. What's wrong? Regards[/url] View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4030006#...
