Before you look at your own code again you should ask yourself - what
is the main difference between application and applet?
(one runs locally, the other runs on remote client)
I tried by using following code:
Following code I just made for Demo purpose as application
System DSN is: AIS
Table Name is: Name

It means there is no problem in connectivity
