Hi; 
 
I use into my web application, the Ibatis tool for database access.
Another external application stores into this database of the documents
(pdf) in using of the fields BLOB. My web application must load and get
these documents to publish them on line. 
questions : 
    - How get these documents from BLOB field to copy them into a
directory server. 
    - which is the best implementation to write a insert request with
Ibatis
 
Best regards;
