It seems that I have different version of class org.jboss.ejb3.remoting.IsLocalInterceptor and this is right, but I have a problem when I tried to fix this one. This class apear in my repository in jboss-ejb3-client-4.0.4.jar and in jboss(jboss-ejb3 I have) in jboss-ejb3.jar. Those jars didn't match but if I change only the class IsLocalInterceptor from one to another the test will work, but I can di that, I have to find a better solution. I don't know exactly why I have an older version on jboss server because I have the last version on jboss-ejb3. Do you have any ideeas ....
