Dolphin Applet

Hi all,
     I'm developing my web site using seaside/D5Pro/XP. It is good but was
lack of the ability like "javascript" in order to make my web pages more
dynamic.
     I needed it  for special-purpose reasoning or testing , for I had many
evidence-based medical prediction rules to be implemented  in each web page.
    The rules could be quite complicated with some sophisticated calcuation
processes, so it is impossible to be put the rules simply in one IA
Component subclass ( I even consider to try to learn to use so-called
metaprogramming technique,  in oder to change the run-time method (
calculation and rules ) behaviour dynamcially, so I can maintain only fewer
IA Component classes  and each web page that was rendered by those classes
still had its own different specific prediction rules and unique executable
calculating methods querried from the database. But I was not planning to go
further that way, if I had better choices).
     I found the easiest way is to shift to write these rule codes as the
JavaScript or Java applet in each web page, but  I knew that once Dolphin
had plug-in support for IE5 in D4, but not for IE5.5 above ?( even Squeak
had Squeak plug-in in SqueakLand, http://www.squeakland.org/).
    Is this feature available now for D5, D5.1 or future D6? and are there
any tutorials or programming samples to teach how to use it ? It confounded
me, since those "Web Plugin Builder", " Web Deployment Kit" packages are
still alive but there are no comments about the current support status or
clear coding examples.


Best regards.

The web applet feature is still available for Dolphin 5 and 5.1 but, as you
rightly point out this does not work in the more recent Microsoft browsers.
It is likely that we will remove it in Dolphin 6.

Do you have control of the server?  Do you need a secure server?  If the
answers are yes and no, respectively, you might consider replacing the
entire web server.  Squeak can do that out of the box, or it might be
possible to port Comanche to Dolphin.

At one point in my recent efforts to free myself from WinCGI [1], I threw
together a very simple web server in Dolphin using code stolen from Squeak's
PWS.  Unfortunately, it depends on some things that I can't easily make
public, but I certainly can file out the HTML-specific parts as a starting
point to anyone wanting to take up the task.  Some theft from the sockets
connection samples and probably more theft from Squeak later, we'd have an
open web server fror Dolphin.  Any takers?

Have a good one,

Bill

[1] My production system uses a commercial server that will hopefully mutate
into yet another Apache installation.  The switch away from WinCGI was a big
step in that direction.

    Is it only partially removed ( only those components to IE Browser
applets)? So, we still had The Web Deployment Kit (WDK) to export non-web
based Smalltalk binary classes  via transportation mechanism and executed
its functionality as part of a normal application just as its package
comments describe.
    I cann't understand it without specific examples, so, could we find
coding examples in the current public packages or tutorials that are already
implemented using this methodology?


Thanks.

Hi, Bill:
   Thanks for your kindly help.

    Yes, web security is a great concern for e-commerce. but, now, I'm not
going into it since I builded my web site only for experiments and
self-learning and was not quite mature to the point that I have full control
of my web server's detailed inner working. So far, I didn't know the
weakness of the Dolphin's Swazoo/HTTP frameworks that I'm using.
   It will be better if there are mature web server available, such as the
most popular one your mentioned, Comanche, be ported to Dolphin, to help me
to have that ability directly.

    I'm willing to have the opportunity to learn more, in order to make my
web services more fully potential.
    I will try to learn in Squeak for the reasons as you mentioned that it
already had good web capability to support out-of-box plug-in, updating open
packages available from SqueakMap and many good coding examples.
The only drawback for me is that it doesn't support Unicode String. I could
use only English in it.
     It would be a great opportunity for me to have your help from your
experience and share the codes to me.

   Sorry, I cann't understand what WinCGI is. Since I knew that the Apache
server is usually Unix-based, so,  you may mean to build the production
system in Unix but not in Windows? is it right?


Best regards.

Hi Bill,

There is always Swazoo, available at
http://www.dolphinharbor.org/dh/projects/swazoo/index.html.  It's a
nice, free, dolphin based web server.  Steve Waring has done quite a
bit of work on this since my initial port way back when.

Thanks,

Jerry Bell

Good point.  I have perhaps unfairly focused on its web services features,
to the point of forgetting that it does more than that.

Have a good one,

Bill
