Hi prahu,
I don't think you can get automatically the latest data in the applet without calling the applet again.
If anyone can give a better solution they are welcome.

I understand that you are trying to establish database connectivity through applet. This would mean that DSN shall be created on all the user machines ( wrong approach ) or use JNDI services of the server. I do not know How you are implementing it. If the applet is not displaying lot of information then you can use socket to get the data. After every given time applet will open socket connection to the server and get the data and update the GUI . This will avoid updating the entire page. Many sites which has continuously changing data( shares ,stocks) use this method to display current data. However when applet tries to open the socket security manager will throw exception which shall be taken care of .You can try with appletviewer ( no security settings are required).
