[Zope] Rich client side questions

[Theodore Patrick]

We have been doing some work with Zope as a data exchange server via HTTP.
We are using it to broker data to/from an Oracle database,
we chose this method over other protocols simply because of Firewall
issues(nobody blocks HTTP-Port80).

As Java can perform HTTP get() and post() requests both embedded in a web
page and as a Fat Client(no-browser), It seems relatively straight forward
to enable the client to exchange data anywhere on the internet.

Actually we have been working with Macromedia Flash on the Client side.
Version 4 of Flash allows you to Set Variables via Get and Post requests. It
is a relatively simple operation and is quite painless.

-------------------
Look into XML/RPC!

You could have your client format an HTTP request as XML and perform
functions so that only necessary data goes over the wire. Resulting data
sets can come back as XML as Java can parse an XML Document/Data Set.

Setting up the Zope to do this is easy!

Enjoy,

Subject: [Zope] Rich client side questions


I have a project which fits very well with Zope's view of the world,
except for the client side GUI[1].  I need the ability to directly
manipulate objects with a minimum amount of traffic going back to the
server[2].  I'm currently leaning toward using Java applets that use a 
CORBA like protocol with Swing[3].  

The Java solution solves the interaction issues, but cuts out Zope as
a method of getting data to the Java applet.  The questions are:
  o Any other ideas besides Java to do the client side work?
  o If, I'm stuck using Java should I add a protocol such as NTTP-NG
    to Zope?
  o How well does Zope without Apache serve up applets?

Footnotes: 
[1]  HTML isn't going to cut it.

[2] One example of this mode of interaction would be a plot.  The user
creates a plot and interacts by clicking and selecting the plotted
objects.  Another example is sweeping out a region with a mouse.

[3]  It may be HTTP-NG or IIOP.
