Re: How would YOU write a client/server Java applet today?

Hi
I have developed a Applet which basically displays
data fromm AS400 in graph, pie, chart, or gant bar,
also the user can click on applet and change values.
I have basically used Applet-Servlet communication.
This can be done rather easily and is roboust,
also since the communication is over HTTP/HTTPS can be
made secure,
I am using websphere as application server, and JT400
classes to access data via stored procedures and call
AS400 RPGLE programs,

You can also explore the use of Java webstart, it also
looks promising
