What I have understood from your message , you get some informations
from user (e.g. login and password) and then retrieve some data from
database upon that parameters. Now you want the fechted data to be
sent to applet.
there are two solutions.
1) Connect your applet with database, provide complete interface in
applet, user logins and get his data on the applet screen
2) Fetch data from database using ASP,JSP etc and send it to applet
in form of parameter using <PARAM > tag.
if you still have any problem let me help you out.
