Hi,
I am trying to insert an uploaded file (media) into a blob column in oracle and I think I hit the 4k limit.
1. I have defined media as byte[] in my POJO. I don't want to define it as java.sql.Blob (ref to
articlehttp://forum.hibernate.org/viewt ... racle+blob) 'cos my user may be using some other DB instead of oracle.
2. I set the sql-type=binary in the hbm.xml map
3. I am using the oracle 10g driver (ojdbc14.jar)
4. I set this
## use streams when writing binary types to / from JDBC
hibernate.jdbc.use_streams_for_binary true
Everything works as long as the file is below 4k. Then, I start getting this error:
encountered SQLException [No more data to read from socket];
Any suggestions is most appreciated. Thanks.

Code between sessionFactory.openSession() and session.close():
I use Spring to deal with it
<bean id="transactionManager" class="org.springframework.orm.hibernate.HibernateTransactionManager">
