Typically, you might serialise to a ByteArrayOutputStream then write the byte array to the BLOB. To read, get the byte array from the BLOB then deserialise from a ByteArrayInputStream based on that array.
If you don't know how to serialise/deserialise to/from streams, read up on Java Serialisation, independent of databases.
As a possible optimisation, note that Blob objects have built-in InputStream and OutputStream functionality, from Java 1.4 onwards.

Original Poster sent me a private message asking for code for this. UseTheForumNotEmail
No need for me to go writing example code. Sun's own ought to suffice. See Sun's BLOB example code.
