Hi,

I am getting this when running HIbernate objects under JBoss as a MBean:

java.lang.ClassCastException: cannot assign instance of net.sf.hibernate.proxy.SerializableProxy to field com.db.device.NetPortalSubnetwork.network of type com.db.device.NetPortalNetwork in instance of com.db.device.NetPortalSubnetwork

If I run the same code outside of JBoss everything works fine !

pls help,

TIA,

--steve p.

(mappings)

Code:
  <class name="com.db.device.NetPortalSubnetwork" table="subnet" mutable="true" polymorphism="implicit" dynamic-update="false" dynamic-insert="false" proxy="com.db.device.NetPortalSubnetwork">

Any cglib mismatch in your CP ?

You should not have both of those JARs in there! From memory, just cglib-asm.jar.

Tried with each of them (one at a time)
Same result ...

What else ... :(

Thanks.

With 2.1.1 I get errors even before , when parsing the mapping files. Looks like cglib2 hangs with something like:

Code:
..................
reflection optimizer disabled for: com.db.device.SupportedNeType, IllegalAccessError: null
[ServiceController] Problem starting service jboss.jca:service=HibernateFactory,
java.lang.IllegalAccessError
at net.sf.cglib.core.ClassEmitter.setTarget(ClassEmitter.java:87)
...................

where the previous versions of cglib worked fine ...


Quite disappointed ... :(

Thx again.

A few things to look into:

1. How are you packaging your SAR?

2. For Hibernate 2.1.1, the only JARs you need are:

hibernate2.jar
cglib2.jar
commons-collections.jar
commons-logging.jar
dom4j.jar
odmg.jar
ehcache.jar

3. There is a FAQ related to your XXX problem: http://forum.hibernate.org/viewtopic.php?t=926219&highlight=illegalaccesserror

4. You don't need any Hibernate related JARs in the lib directory any more - they can live in your SAR or EAR. Check out http://www.hibernate.org/66.html

This is surely some cglib problem, please double check that you have only cglib2.jar in your classpath, check all JBoss directorys. Compare http://hibernate.org/74.html#A3

OK, I got it running with 2.1.1 (CGLIB2) but I still have the original problem:

java.lang.ClassCastException: cannot assign instance of net.sf.hibernate.proxy.SerializableProxy to field com.db.device.NetPortalSubnetwork.network of type com.db.device.NetPortalNetwork in instance of com.db.device.NetPortalSubnetwork

If I run the same code outside of JBoss everything works fine !

I made sure only CGLIB2 is in the JBoss directories.

Please help [again]...

Thanks so much!

I don't use proxies at all. Hmmm, can you try running it without the proxy tags in the class metadata?

Can you post the code and the full stack trace you are getting?

Also, log it in Hibernate JIRA.


Sorry I can't help on this too much,

This is some problem with serializing your objects as they are passed as arguments into the session bean. There are some issues in JIRA related to this.

Do they implement Serializable?

They do, as far as I know.
But I'll double check.

Thanks again.
