I'm a little newish to java, but really new to sql server and datatype image.
I am trying to extract files from the database and store them locally on the computer. I have retrieved the image contains from the column with rs.getBlob, and have saved them to the system with the following code:
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(fileName));
bos.write(blob.getBytes( 1, (int) blob.length()), 0, (int) blob.length() );
This does save the file, but I can't open the file no matter what I change the extension to. The kicker is that I don't know what each file is suppose to be, the database does not contain the names of the files either.

So it ended up being the way the data has been stored into the database. It's converted to another proprietary format. I have tested my code on another table in the database that has pdf's stored as blobs and those work fine.
