ORDER BY NAME


Alrighty, I've looked in the docs, annotations, tutorial, and the forums, and cannot find a solution to my specific problem.

What I'm looking at, as specified above, is that I have a Serializable datatype mapped to a Serializable type in the hibernate object, comming from a Blob in the Oracle database. I am able to enter data into the database using Hibernate fine, but when I execute the query to return a collection/list of hibernate objects containing the Serializable object, it gives me teh "could not deserialize" error with the root cause of a java.io.StreamCorruptedException when it goes to initilize the CustomeObjectInputStream object using the input stream passed to the deserialize method.

I really have no idea why its complaining about this Serializable object, since it should be creating the ByteArrayInputStream properly from the generated Byte array from Hibernate.BINARY.get(rs, name); The header shouldn't be corrupt, should it?

I've tinkered with the mapping document and the datatypes to no avail, and the last state given here, is the most recent (moving from hibernate types to java types, and removing a many-to-one mapping for a fk that I had mannually put into the mapping that was not generated using the Hibernate Tools).

I appreciate any and all help that can be given, and I thank you in advance for you time and information.

I also faced similar issue.
I downloaded the latest Oracle Drivers (10G) and used it. The problem was resolved. May be you want to try that
