SQL UPDATE does not work

Question

Hey Guys,
I have an update sql query which does not work with PreparedStatement object. Heres the code snippet:
PreparedStatement pstmt;
int numUpd;
pstmt = con.prepareStatement(
"UPDATE item_articles SET dataFile=? WHERE itemID=?");
con.setAutoCommit(false);
pstmt.setBinaryStream(1,fis,(int)file.length());
pstmt.setInt(2,item.id);
numUpd = pstmt.executeUpdate();
con.commit();
What I am doing here is that setBinaryStream(...) will upload a file into the DB. The query executes, theres no exception thrown, but my table shows empty field for the file. Note, there are no exceptions thrown from this query.
If I do the same thing for an INSERT statement, it works. The file gets into the DB. So , the file is there on disk, and theres no problem with it. Just that it does not work with UPDATE.....any clues ???
thanks
Askar

I think UPDATE commands dont work well with blobs.
I use to select the register with a ResultSet, then get a BLOB Object from the column.
So you can use a OutputStream to Upload your data.
