Brett,
Thanks for your detailed reply.   The application will be deployed in an
internet environment.   A few more questions. Some of our applets will have
12 - 15 tab pages each w/its own set of data.  Is it feasible to get an
quick enough response with this type of gui?  Also, what packing tool did
you use to produce the Jar files?  And, if can in a sentence or to, explain
how  you used XML for communication between the applets and the backend?

Thanks again

Jeff

Jeff, will your application be deployed in an intranet or internet
environment?  This might make a difference in the solutions that
are available.  Just for your information, I faced as similar situation in
the development of a Network Management System used to
control and manage fiber optic communications equipment that we
manufacture.

 I needed a robust and complex gui with things such as greying out fields
depending on the selections of other fields, validation on
fields as they are entered, indicating to a user a field has been changed,
etc.  These needed to be done on the client side.  I
looked at a few possibilities, namely JavaScript or Java applets.  At the
time Sun's Jump Start was not available.  I chose to use
Swing based Java applets.  To get around the differences in browsers, I
chose to use the Java Plugin to provide this stable (fairly)
environment.  In addition, in the back end we are using Tomcat with
servlets, JSP pages, and XML as the communications between our
Java applets and the backend.  I chose Java over JavaScript because of the
complexities involved in managing browser specific within
JavaScript and also because of the better development and debugging
environment I had in Java.

Using a packaging tool that produces Jar files with the absolute minimum
need for the applet, we are able to keep out applet size
down to between 250k and 350k.  Once downloaded the applets are cached, so
this is pretty much a one time hit.  Our applications are
quite responsive and have the gui needed.

Just to let you know what we did.
