Hello, I'm trying to read a serialised handle (EJBHandle serialized to an ObjectOutputStream) and I have:

java.io.OptionalDataException

I'm not sure "where you are" when you get the error, but typically classes from "java.io.*" are not legal in an EJB environment. Maybe you can save your handle in your special JNDI environment instead?

Couold you please show me the code that is writing and reading this?

Could it be you are using an inherited class that overwrites some methods?
