Hi, I'm trying to get a Swing application to connect to an annotated stateless EJB that running under JBoss 5.0 beta1. Since there is some confusion as to which Jars I need to run I've been using jbossall-client.jar on the client. It seems to be imcomplete though as I had to add jboss-logging-spi.jar and I am running into an exception while trying to log on. I have not found the jar containing org.jboss.security.plugins.JBossSecurityContext yet. The exception I'm running into is below. Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/security/plugins/JBossSecurityContext at org.jboss.aspects.security.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:47) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:77) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessRemoteProxy.invoke(StatelessRemoteProxy.java:102) at $Proxy0.openSession(Unknown Source) at com.vanbelle.hydra.client.ejb.Test.main(Test.java:49) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4017952#...
