groupscheme-user Mailing List for Groupware in Scheme

Windows XP Pro:
-Java Web Start:
-- Create Shortcut.  Unable to create a shortcut for GroupEdit: v1.1  
7/2/04.  Invalid filename.  Please make sure the application title is  
valid.
-- Seemed to work fine.
-Signed applet:
--WinXP Pro, IE6, via signed applet, double-clicked on visit-log, also  
single-clicked on visit-log & pressed JOIN, both times got this:

ERROR in Action in reponse to an AWT  
eventjava.awt.event.ActionEvent[ACTION_PERFORMED,cmd=Join] on

Mac OS X:
-Java Web Start: Clicking on this link in Safari triggered a download  
of grewp.servlet, after which nothing happened.  I seem to recall that  
JWS apps on my Mac had .jlnp extensions.  Am I remembering correctly?
-Signed Applet:
--Worked great EXCEPT (!!!) I was in a tab of Safari, and clicking Edit  
in the signed applet CLOSED MY SAFARI WINDOW (and thus, all the other  
web pages I happened to be visiting).  It EXITED SAFARI too.  I'll have  
to try again with the signed applet in its own window. [...]  I tried  
it again, it closes all of SAFARI.

GNU/Linux (Fedora Core 1, FireFox 0.8 browser):
- Java Web Start: Works great.
- Signed applet.  Everything I wrote about Mac OS X + signed applet  
applies, except the browser is FireFox instead of Safari.  The behavior  
of the whole browser closing when I select File/Exit from the applet is  
the same.

I'll have to try Solaris later.  The kids want to go canoeing!

We are about to make a release of a Collaborative Editor
(GrewpEdit) implemented in JScheme and would appreciate
any feedback from the groupscheme and JScheme community about this tool.

      http://tat.cs.brandeis.edu:8090/grewp

We are releasing it as a Java Web Start (JWS) application, a signed 
Java applet,
a double-clickable jar, and a source distribution.

I am especially interested in seeing

   1)  whether the JWS and applet versions run on various Microsoft 
operating
        systems (we've tried one version of NT and it worked OK under 
Netscape and IE)

   2) whether there is a noticeable (or annoying!) lag time for people
        using the editor far from Boston. (There is no noticeable lag 
when I
        use it from home. I'm about 10 routers and 10 miles away on a
        wireless link to a DSL connection).

The current version allows you to connect to a server in Boston just by
supplying a username (any will do!). You can also create your own
Grewp server and have people connect to it.

The client editors send scheme terms over a socket to a server which
resolves conflicts and sends back official transformed editing 
operations.
The clients then apply these operations to their textfield. Thus, this 
is a
full duplex model where a slow connection will cause a noticeable lag.
Each character you type goes to the server, gets transformed and sent
back to your machine before it appears on the screen.

We are working on building a Jupiter/NetEdit model that uses speculation
to remove the lag time, but its not up yet. We are also working on a 
mini-emacs
interface for the collaborative textarea (which would allow users to 
define their
own emacs bindings in Jscheme ...) The next version of GrewpEdit will 
allow
the user to select from a wide variety of widgets including whiteboards,
cobrowsers, and other groupware widgets...

Cheers,
---Tim---
