Problem during marshalling/unmarshalling

[msaeed]

Hi

I'm using JBoss 4.0.3. From my session bean I'm writing an object from the client and then trying to read it. An exception is thrown while returning from the method call that reads the object. The persistent object being returned has a List of another persistent object which is retrieve by LEFT FETCH JOIN.
Any input will be appreciated. The exception is as follows:

It seems you have different versions of the hibernate jars on the client and server side.

Hi, imranpariyani,

Recently I got the same error while invoking remote ejb from jboss 4.0.5 to 4.2.0. Can you share your solution with me? Thanks a lot!

Hi lin

Well for me the problem was an object somewhere within the entity which was not Serializable .. i was passing that along with the entity ..

if your having the same stacktrace (i.e with ObjectInputStream) then i guess u also must be passing an object which is not Serializable along with the entity .. and if there is something with SearialversionUID then it has to do with different versions of hibernate jars

I guess u might have already found the problem but just in case if someone else fumbles upon the same

Regards

Imran
