Insert file to Oracle's BLOB

[kwwong wong]

I using the following codes to insert the file in RAW LONG Column and it works O.K. But when I change the column type to BLOB, it throws the exception.

File file = new File (args[0]);
InputStream inStream = new FileInputStream (file);
PreparedStatement psmt = conn.prepareStatement
("INSERT INTO vp_doc (name,doc) VALUES (?, ?)");
psmt.setString (1, args[0]);
psmt.setBinaryStream (2, inStream,(int)file.length () );
psmt.execute ();

Below are the exception :

Exception in thread "main" java.sql.SQLException: No more data to read from sock

You may want to have a look at the LOB Datatype Sample on OTN

The sample in OTN is an client application and using SELECT FOR UPDATE. Can I using this sample in Web Application ? I remember that SELECT FOR UPDATE cannot use in WEB application, is it true ?
Thanks
