Well this is just a few lines of code in java, but it's a bit of a tough 
task with a java applet. You will probably need to arrange for the jdbc 
driver to be downloaded by the browser along with the applet. That will 
make the applet a little too bulky to use.

Since you have java at both ends of the wire, instead of using jdbc 
directly from the applet, you might want to carry out all the database 
interaction on the server (for which j2ee is well equipped) and pass 
back objects or make use of the XMLencoder and XMLDecoder classes.
