Hi Michael,
I'm curious...did you ever try to import the ION Java pkg directly
into your servlet? While I haven't worked with servlets specifically,
I have successfully used ION Java in other situations where no applet
was used -- i.e., in stand alone Java applications. If all ION is
going to do in the above application is sit back on the server and
process (no display), then I would think it would work fine. Or,
maybe it was the IONCanvas that was giving you problems? Regardless,
if you can provide me with a simple, yet relevant example of a servlet
implementation, I would be happy to take a look at it. Lastly, did
you ever explore ION Script in this context? Thanks in advance for
the additional information.
-P
