That doesn't look like a "general" Java question. Moving.

Have you read the JDBC tutorial yet? It contains code for dealing with BLOBs.

Feel free to post a more specific question to get more specific help.

As Jeanne mentioned, the JDBC is a good way to deal with databases. I use JDBC to perform all sorts of operations on a MySQL database without much trouble. Since you're storing a file, you could simple open a stream to the file like normal and read it directly into a String, for example, and save the String into a BLOB.
I agree. Here's the link:
