Serialization error

Hi. I'm using ObjectMessage wrapping a custom value object.
The object implements Serializable interface and, in my development
systems (OSX and Windows with Java 1.5), all works good.
I'm trying now to setup a test environment based on Linux and the latest
Sun JVM, but OpenJMS throws an exception (MessageFormatException)
when I get back the value object from the ObjectMessage (getObject()).
It's seems that the JVM don't find the class (the related exception of
MessageFormatException is ClassNotFoundException) but the value
object is serialized by another thread of the same application.
Any suggestion?

Thanks,
Andrea.
