The ear file deploys fine but whenever I call a method that has (default) package visibility the call never makes it into the method and I get no error whatsoever. The calling class and the called class are both in the same package. When I make the method public it works fine. I have seen this in previos 3.0 candidate releases but before I was getting an Access error, now I get nothing. ---------------------------------------------------------------------- >Comment By: Scott M Stark (starksm) Date: 2002-07-27 21:21 Message: Logged In: YES user_id=175228 An issue was found where duplicate class loaders could be created and this would cause this problem. Try your case with the latest Branch_3_0 code and see if this was the cause. ---------------------------------------------------------------------- Comment By: Steve Wolfangel (swolfangel) Date: 2002-06-28 12:42 Message: Logged In: YES user_id=541224 I am having trouble reproducing in a simple test case. I did add some debug to my original code. Instead of catching exception I am catching throwable. Below is the stack trace I am getting. I am still trying to reproduce in the test case. 2002-06-28 14:36:34,741 INFO [STDOUT] StartupStateController.indicateSystemShutdown() 2002-06-28 14:36:34,756 INFO [STDOUT] try to access method com.metamatrix.common.config.CurrentConfiguration.in dicateSystemShutdown()V from class com.metamatrix.common.config.StartupStateController 2002-06-28 14:36:34,756 ERROR [STDERR] java.lang.IllegalAccessError: try to access method com.metamatrix.common.config.CurrentConfiguration.in dicateSystemShutdown()V from class com.metamatrix.common.config.StartupStateController 2002-06-28 14:36:34,756 ERROR [STDERR] at com.metamatrix.common.config.StartupStateController.i ndicateSystemShutdown(StartupStateController.java:145) 2002-06-28 14:36:34,756 ERROR [STDERR] at com.metamatrix.platform.util.MetaMatrixController.killS erver(MetaMatrixController.java:162) 2002-06-28 14:36:34,756 ERROR [STDERR] at com.metamatrix.platform.admin.apiimpl.RuntimeStateAd minAPIImpl.bounceServer (RuntimeStateAdminAPIImpl.java:942) 2002-06-28 14:36:34,756 ERROR [STDERR] at java.lang.reflect.Method.invoke(Native Method) 2002-06-28 14:36:34,756 ERROR [STDERR] at sun.rmi.server.UnicastServerRef.dispatch (UnicastServerRef.java:241) 2002-06-28 14:36:34,756 ERROR [STDERR] at sun.rmi.transport.Transport$1.run(Transport.java:152) 2002-06-28 14:36:34,756 ERROR [STDERR] at java.security.AccessController.doPrivileged(Native Method) 2002-06-28 14:36:34,756 ERROR [STDERR] at sun.rmi.transport.Transport.serviceCall (Transport.java:148) 2002-06-28 14:36:34,756 ERROR [STDERR] at sun.rmi.transport.tcp.TCPTransport.handleMessages (TCPTransport.java:465) 2002-06-28 14:36:34,756 ERROR [STDERR] at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler. run(TCPTransport.java:706) 2002-06-28 14:36:34,756 ERROR [STDERR] at java.lang.Thread.run(Thread.java:484) ---------------------------------------------------------------------- Comment By: Scott M Stark (starksm) Date: 2002-06-27 13:53 Message: Logged In: YES user_id=175228 Then can you send an ear that demonstrates the problem.

I don't think this is a JVM issue because this works fine with WL6.1 using the same jvm. I am also able to run the code outside of the appserver (minus the EJB and remote object.) I was wondering about security also, is there anything I can try? ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2002-06-27 13:00 Message: Logged In: NO Then that looks like a JVM bug. If the container isn't doing any proxying, your call should be being executed and at that point (when just regular classes are involved), the JVM is in control. The only thing I can think of that would lead to a different conclusion is that there might be SecurityManager/ClassLoader issues -- but then you'd expect an exception would be being thrown somewhere. Do the logs show anything when this failure happens? ---------------------------------------------------------------------- Comment By: Steve Wolfangel (swolfangel) Date: 2002-06-27 12:23 Message: Logged In: YES user_id=541224 Object B, C and D are just normal classes, not EJBs ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2002-06-27 12:20 Message: Logged In: NO So ObjectB, ObjectC and ObjectD are all just regular classes? Or are they EJBs? ---------------------------------------------------------------------- Comment By: Steve Wolfangel (swolfangel) Date: 2002-06-27 10:52 Message: Logged In: YES user_id=541224 Here is the actual scenario. Client makes a method call on an EJB EJB returns a remote object to the client. Client then invokes a method call on the remote object (which is in package A) The remote object (ObjectA) then calls a static method on ObjectB (which is in package B) ObjectB then calls a public static method on ObjectC (which is in package C) ObjectC then calls a package level static method on ObjectD (in packace C) this method fails. When I make the method in ObjectD public it works. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2002-06-27 09:42 Message: Logged In: NO I don't think this is a bug. EJB's deal w/ each other through container-provided interfaces, backed by proxies whose package is not under control of the EJB author. Chances are good that the class actually making the call is NOT in the same package as the target class. If there is an EJB implementation class calling another EJB impl class method statically w/out going through the container (i.e. EJB2.someStaticMethod()), then it's a bug but it seems very unlikely that that's the case, and if it is it would be a JVM issue (and certainly bad design). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=574238&group_id=22866 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
