Hi Clinton; Yes I have mapped directly to a byte[] with iBATIS (no problem) => I get well and correctly the blob via Ibatis. But My question is how analyze the byte array for extracting the data which contains. Yes my blob into the database is very big (about 20 Mo) but I must from of these data to fill of the objects. Why use directly jbdc instead of ibatis ? Ibatis is not adapted to treat the blob of important size (performance problem) ? Can you give me more details.
