Applet to insert data to my database

[robbietherobber]

I am only begining to work with Java and I have hit a point which i just cant understand.

I have a very simple applet which is suppossed to send data back to an access database.
I have the same thing in an application and it uses the same odbc link and sends info back to the access database but i cant get the applet to do the same.

so I must be missing something but i cant see it.

I will add the applet and the two java code pages

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

Now what exactly is your issue? Does the code throw an exception, does the data just not make it back to the server, or is the information displayed on the applet incorrect?

If possible try and figure out where the problem is so that we don't have to figure out all of the code just to find the issue.
