Nick Jones worte a solution for us, how to test classes in multiple jar files. Example see below, which can be used as a base test class:
public class MyEJB3UnitTestUtility<T> extends BaseSessionBeanFixture<T> {
static {
MetaDataCache.addClasses("com.pioneer.wipe.common.log.injection.ejb.PortalLoggerInterceptor");
}
public EJB3UnitTestUtility(Class<T> classUnderTest) {
super(classUnderTest, null);
}
}
