I have successfully gerenated a DAO ibatos interface using Abator for Ibatis that contains a BLOB field.
I see the getter/setter methods for getting this data. My concern is that this approach seems to first read the whole BLOB into memory and then i pass it out to an outstream. The servlet is simply serving an image from the database. The files could be quite big and i could have many users in parallel. I am concerned about running out of memory.
I see in basis resultset you can use getBinaryStream on the blob and then read in and out as normal.

Can someone help me understand how to do this with Abator/Ibatis or whether in reality i will not have a problem?
