i have this scene:

- A j2ee web application developed with jdeveloper 10g
- this application has 3 layers ... DAO, Bussiness Objects, Presentation
- The DAOs are using hibernate to access an oracle database
- The BO are Stateless Session EJB
- The Presentation is mostrly web, but theres is a small swing client

If everything is executed from within jdeveloper works ok.

But when i run the swing client outside jdeveloper i get this error

EntidadesFacadeBD - -Error obtenerEmpresaXId: Error deserializing return
-value: java.io.InvalidClassException: net.sf.hibernate.collection.ODMGCollection;
Local class not compatible: stream classdescserialVersionUID=629623989050370
4603 local class serialVersionUID=8306570059535984264

The swing client is calling a remote method on the ejb (remote interfaces)

I doble check the to use the same version of hiberante.jar and odmg.jar on the server and the client ... thats ok

I really dont know whats happend. Any help will be appreciaded

Thanks
Ignacio

You are not using the same jar version.

yes, i doble check it and im using the same jar version ....

the only posibility is that jdeveloper put another jar version in the classpath ... but i cant find any reference

Thanks
