Read file from database

Hello,

I´m new to java and new to this forum, so I hope you will be patience with me :)

What I´m trying to do is this:
I read a file from database, and I need to show this file directly to the user. This file is saved as Blob in Oracle database and I read it in this way:

String sql = "SELECT image FROM pictures ";
PreparedStatement stmt = conn.prepareStatement(sql);
ResultSet resultSet = stmt.executeQuery();
File image = new File("D:\\java.gif");
FileOutputStream fos = new FileOutputStream(image);

byte[] buffer = new byte[1];

//
// Get the binary stream of our BLOB data
//
InputStream is = resultSet.getBinaryStream(1);
while (is.read(buffer) > 0) {
fos.write(buffer);
}
fos.close();

Now I need to "show" this file to the user but I have no clue how.

If you can suggest me...any idea will be welcome.

Thank you in adavnce.
