Large Object

Hi,

I don't want to annoy anyone, but I just can't write a large object.
Code:
File file = null;
FileInputStream fis = null;
try{file = new File("c:/testen/test.pdf");
fis = new FileInputStream(file);}catch(Exception e){e.printStackTrace();}
try{
dat.openDB();
dat.db.setAutoCommit(false);
PreparedStatement ps = dat.db.prepareStatement("INSERT INTO blob_test VALUES
(?, ?)");
ps.setString(1, file.getName());
ps.setBinaryStream(2, fis, (int)file.length());
ps.executeUpdate();
System.out.println(ps.toString()); // shows: INSERT INTO blob_test VALUES
('test.pdf, 390368)
ps.close();}catch(Exception e){e.printStackTrace();}
fis.close();

The table looks like this:

CREATE TABLE blob_test (
  name varchar(35),
  pdf oid
);

Some further questions. How can this funny number in the insert-statement
represent a
binary file? Is it right, that the file lying somewhere on the harddisk can
be written with
this setBinaryStream-command into a db lying on a server?

Thanks in advance for any hint.

Andi
