Hi,

I try to receive a Hibernate Object from the Bea Weblogic Server 8.1 SP5 from Tomcat 5.0 over RMI/IIOP (t3). The object will be fetched without problems, but if I try to send it to the Tomcat the following exception occurs:

<27.01.2006 18.53 Uhr CET> <Warning> <RMI> <BEA-080003> <RuntimeException thrown by rmi server: XXXXXExternalSession_spoxje_EOImpl.login(Ljava.lang.String;Ljava.lang.String;Lja

For me it looks like Weblogic treis to get the Collection that is not initialized...
The Error doesn`t occur with Weblogic 8.1 SP4 (but we have to use SP5).
Also the error doesn`t occur if I deploy the Webproject on the Weblogic instance.
I also have an Testclient, that has the same problem (so Tomcat isn`t the problem).

I use the CMTTransactionFactory and I´m calling session.flush() on leaving the SSB.

My Environment:

Weblogic 8.1 SP5 / Tomcat 5.0 / Hibernate 3.0.5 / Oracle 10g / Jdk 1.4.2_08

I think Bea has something changed with the RMI/IIOP.

Is there a known issue with SP5?

Name and version of the database you are using: Oracle 10g

Can anyone confirm this problem?
Is this a known issue or am I doing something wrong?

Thanks in advance.

This topic was here some days ago. They found out that it is a bug. I am not sure if this also applies to your exception.

Just search

Sebastian

I think you reffered to this bug http://opensource.atlassian.com/project ... e/HHH-1392 . It should be fixed in 3.1.2 so I switched to this version, but that doesn`t help. I thin the problem is this line in the Exception:
weblogic.corba.utils.IndirectionValueHashtable.get(IndirectionValueHashtable.java:119)

The complete Excpetion now is:

Is there someone, who would take an existing project, which runs on Weblogic 8.1 SP Level < SP5 and test it on SP5, to confirm if this is a bug?
The important thing is, that the client, which accesses the SSB isn`t deployed on Weblogic, but for example Tomcat...

Thanks in advance.

Or should I commit a new bug?

Meanwhile I tried to deploy the application on Weblogic 9.1. The same problem occurs there. Has someone successfully deployed an Application with Hibernate, EJB and RemoteClient (e.g. Tomcat) on Weblogic 9.1, where Hibernate Objetcs are passed to client and are not fully initialized?

I'm shaky on my RMI, but a vague guess from the stack trace would be as follows:
You're getting lazyinitializationexception. This is because a related collection property is being referenced, but there is no hibernate session to go tot eh DB to fetch the related collection.
My guess as to why this is happening? when serializing over RMI the RMI code has to get* each property of the object to marshall to encode it to send it over the wire. When it tries to get() that property it can't, and it vomits.

Things to try to see if that is the problem: remove any related collections from the object you are trying to marshall over RMI. If it JUST a bunch of properties with no references to other objects it should marshall just fine.

If that is the case, either set the property that is causing the problem to be eagerly fetched in your mapping document, OR use the session.intialize(yourobject.getTheCollection()). This will, IIRC, perform the fetch quite nicely and then all of the getters on your object will return nice things that can be marshalled over RMI.

This is just my first stab after glancing at the stack trace, YMMV

You`re right. This only happens if collections are not initialized. But for me it`s not an option to initialize the, because in this case I have to load to much data from the db.

there are several options. ONE- create a parent class that doesn't have the collections as part of it. when you want to get one that is serialized, look up the parent and send it. when you need in your main app the object that has the lazy loaded collections, look up the subclass.

so:


this allows the RMI marshalling process to serialize everything it finds on the parent class, but allows you to utilize the child class locally to get at the collections.

Ok, I can create a parent class, but I do not know, why it is working with Weblogic 8.1 SP4 and not with SP5 or Weblogic 9?
Is there eventually a bug in Weblogic or Hibernate?

Probably you have different hibernate versions on your containers, it was a bug fixes related to this issue in 3.1.1 and 3.1.2, but You must initialize as many objects as you need on server before to return from remote method. It is possible to customize hibernate to initialize serialized objects on demand using callbacks, but it is bit complex to implement. http://www.hibernate.org/377.html I will update this version with working implementation for entity proxies (custom tuplizer for 3.1), but I do not have time to finish it for collection lazy initialization at this time (it needs custom persister and custom collection classes to hack serialization).

Unfortunately I have the same versions of Hibernate (3.0.5).
I also tried version 3.1.2, but it doesn`t help with the problem.
I don`t make calls on the collections either on the server nor on the client. It happens while Weblogic is marshalling the objects. On JBOSS the problem doesn't exist...

verify this method in hibernate source code " org.hibernate.collection.AbstractPersistentCollection.read" there is something wrong, it must not call "initialize".

Sorry, I see it is a side web logig specific effect:

You need to hack "PersistentSet.equals" to fix this issue.

THX!!!
This was exactly the problem. I patched the equals and hashcode method and it works.
But I also had to remove my equals and hashcode methode in my hibernate objects, because they used the id...
Can I check if a object is a proxy, e.g. by calling instanceof, or is there a good solution for equals and hashcode methods in normal hibernate objects?

By the way, was this a bug of Hibernate, so that it would be fixed and I don`t have to patch the jar in further versions?
