serialized objects and JDBC driver - Mailing list pgsql-jdbc

I am attempting to serialize objects into Postgresql using the
JDBC driver. I am attempting to do this the standard way
using Object and Byte streams.

To store the object to the database in a text (blob) field I use the
following code to turn my object into a byte[].

             // create the serialized object and store in the database
             EncryptionInfo serObj = new EncryptionInfo(32, 32);
             ByteArrayOutputStream bos = new ByteArrayOutputStream();
             ObjectOutputStream p = new ObjectOutputStream(bos);
                 p.writeObject(serObj);
                 p.flush();
             byte[] data = bos.toByteArray();


This seems to go into the database with no errors.
However when I retieeve the data using the following code...

ByteArrayInputStream bis = new ByteArrayInputStream(data);
         ObjectInputStream p = new ObjectInputStream(bis);
         EncryptionInfo ei = (EncryptionInfo)p.readObject();

I get the following error...
InputStream does not contain a serialized object


Thanks.
