Java compatibility

J

Jez Naisbitt

Hi Guys,

After a break of 2 years I'm now re-visiting the world of java.

I recall on my last foray that I had to stick to java 1.1 so I could deploy
applets from a server and obtain maximum compatibility with the standard
browsers, supplied on all platforms: We live in the pre-press industry where
folk use diverse platforms such as Sparc, Mac, PC (mnimum Win2K, or XP),
using Netscape and Internet Explorer, etc.

I would like to exploit the improvements made to Java in the recent past so
hopefully things have moved along since the Java 1.1 days.

I was wondering if anyone could point me at a definitive answer about the
cross-platform, cross-browser compatibility of Java.

It must acheive the following criteria:

1) Support for Java X.Y must be currently available on the standard
browser installed on a particular OS.
2) Client computers therefore do not need to download 'special
packages':e.g. new JRE, etc.
3) Applet must upload from server very quickly.

Obviously if the JRE can be deployed from the server with a minimal impact
on performace/upload times then I would be very grateful to hear how this
can be done.

Thanks In Advance,

Jez.

In that regard they have not, due to Microsoft and Sun not liking each other.

But applets are a nearly dead technology anyway. Few people use them
for serious applications nowadays. It's all on the server, using
Servlets/JSP/EJB.

I do not know about 'definitive' but this article
will fill in a lot of gaps for you..

.hhmm. I am just getting into the marvels of server side tech now,
and would dearly love to dump all applet development, but I was
wondering if you had a way of doing this
http://1point1c.physci.org/model/?mdl=s82&mag=50&rotx=5&roty=1
without an applet.. ;-)

I am a cheat - I would use a thick client deployed by Webstart, so I
could specify vm versions that do work. Further, I get most of the "Uh
oh - new version of lib needed for all my users" benefits of an applet.
That way, I avoid browser interaction problems, and get the full UI I
want, without needing too much to be installed.

For somewhat less interactive things, server side tech works pretty
well. It all depends on how fast your roundtripping is, and how much
you need to shove down the pipe.

(I suspect tools will appear to let us have a rich UI on the web, with
interactive controls and the like, but they are not here yet. We tried
Flash and the rich app UI front end for a recent project, and really had
problems.)
