    Problem with Lazy attributes - 4.0.3SP1-EJB3.0RC4

    Pieter-Jan Malfait Newbie

      hello,

      when i try to load an entity that has non initialized entites i get the following exception on the client. this does not happen when i initialize the attributes in the session bean before sending the entity to the client. this also didn't happen using 4.0.3RC2+EJB3.0RC3. anyone has any idea ?

      [12:16:42,015] [ERROR] [SocketClientInvoker:274] - Got marshalling exception, exiting

          thank you for the reply.

          but the problem they refer to in the post you mentioned is when SerializableProxy cannot be found. in my case it can be found (hibernate3.jar is in de classpath) but i get a classcast exception when i try to lazily initialize a entity relation with it (which worked under RC3)..

          i also made sure that server and client were using the exact same hibernate3.jar ..

          any ideas ?

            Same problem here: lazily initialized entity bean fields can not be marshalled because of this! The problem is still present in RC5.

              hi, glad to see i'm not the only one with a similar problem. could you let me know when you find a solution ? I will post it here too if I should find it.

              about the problem, a similar problem also surfaced when moving from RC3 to RC4, but this time it's in the server thread. It seems that a SerializationException is thrown when the server tries to passivate a stateful session bean. Again this worked fine with RC3.

              This is the exception:

                i'm not really familiar with JIRA, but would this be a problem to open a JIRA issue for ?

                  ANYBODY EXPERIENCING THIS BUG please speak up NOW!

                  I am surprised nobody else has noticed this as it must be very obvious in any system. Either nobody has upgraded to RC5 yet or there is nobody using EJB3 with a real-world datamodel :-)

                  I can not think of any configuration badness which could cause this problem. And there is nothing in the FAQ or release notes either. To me it looks like a bug in remoting and thus should go into JIRA. I can do that if you like. But given that JBoss developers rather have discussions in the forums than immediate bug reports I thought to wait a little and give them a chance to make a statement.

                    i'm experiencing the strangest thing here..
                    i develop my ejb3 client with Eclipse, and for testing purposes i package it into a Java Web Start so for the testers to download..

                    this bug does not occur in the webstart! very very strange as it uses exactly the same libs as i use in my Eclipse (i just copy the lib dir actually) ..
                    i also checked eclipse and java webstart are using the same jdk

                    this confuses me even more ..

                      That's very interesting! So it seems to depend on the runtime environment. I am seeing this bug when I run JUnit test from within Eclipse that are clients to a locally running JBoss instance. My JUnit tests are using required libraries directly from the JBoss installation directory.

                      What is your use case exactly, phon? Are you accessing JBoss from an application client?

                        i got a JBoss Server (4.0.3SP1) running on a linux machine and i connect to it from another machine (my development machine) through eclipse with a swing client , and the testers connect to it through VPN with java webstart
                        when i'm at work i connect through local LAN, when at home i connect the same way the testers do, over VPN. It doesn't seem to matter wether i'm using the LAN or the VPN.

                        i'm tracing the cause of this problem and i noticed that this doesn't happen for every object. i got a database filled with 1500 generated contacts for testing purposes. When using my client from inside Eclipse certain queries work just fine, other generate the exception.. all queries work fine from webstart though!

                            I have also experienced this -- seems like jboss serialization cannot handle the uninitialized lazy attributes (ClassCastException in ClassReferencePersister.java:42). In my case I can work around it for the time being by using a local interface on the same machine, but I can see how this is an issue for remote interfaces. It would probably be nice if they get serialized but just omit the lazy stuff, and the your coding contracts understand this.

                              you are talking about the exception happening on the server i assume ? i don't really know wether the two exceptions are related.

                              i got (only beginning line of exception):

                              1) On client when loading entity lazy (after sending them over network)

                              are you both experiencing both problems ? or are they one and the same problem ?

                                I believe the jboss serialization is related to your #2 case (you'll see it stems from the ClassCaseException in ClassReferencePersister). It looks like someone filed a bug on it:

                                EJBTHREE-423
