Hi,

is there anybody who can help on my SO question about Hibernate 4: http://stackoverflow.com/questions/20474302/migrate-abstractlobtype-to-hibernate-4-and-spring-3-2

I am trying to migrate from Hibernate 3 to 4. I am using InputStream in my entity class, but I am having trouble getting it working. It seems that in theory, it should be enough to use type="materialized_blob" and set the 'hibernate.jdbc.use_streams_for_binary=true' setting (I have set this in a hibernate.properties file on my classpath and I see ' HHH000407: Using java.io streams to persist binary types' in my logging).

What could be wrong that I get this exception:

Code:
