[Studio] Eclipse Rich Ajax Platform (RAP)

[Pierre-Arnaud Marcelot <pa...@marcelot.net>]

Hi Dev,

I've just discovered a new project at the Eclipse Foundation that has
graduated from incubation and released its 1.0 release: Eclipse Rich Ajax
Platform (RAP): http://www.eclipse.org/rap/

Take a look at the demos provided here: http://www.eclipse.org/rap/demos.php

That's very impressive... Eclipse look and feel inside a Web brower...

Maybe it could be interesting to take a closer look at that and see if it's
not possible to deliver two implementation of UI for our plugins, one with
SWT and one with RWT. The core could be the same and we could only rewrite
the UI for each platform.

Regards,
P-A

Excellent!

So, Alex, you're right... "we better embed Jetty into ApacheDS soon"

It's a good thing we have this on the roadmap.  It's not at all anything
that is difficult to do.  I had already done this
for Triplesec so it's just another task for us.

Thanks for the excellent news and thorough research into this new
technology.  This certainly fills a void and has
a practical use for us at a very low cost.  I like that combination :).

Hi Alex,

I just tested it and I have bad news and good news...

The good news is, it can be very flexible and easy to develop a light weight
AND a rich client with the SAME code, with just a switch of target plaform
when compiling the classes and a simple dependencies replacements in the
MANIFEST.MF file.

The bad news is, not all the SWT classes have been ported yet to Ajax UI
classes so most of our existing plugins won't work with RAP.

I tried to adapt the LDAP Browser to the RAP prerequisites but, we're using
too many classes that have not been ported yet and the code have thousands
of errors that we can't fix.

However, I managed to get the Apache DS Configuration Plugin almost working
inside RAP.
Here are some screenshots of what it looks like :
http://people.apache.org/~pamarcelot/ApacheDSConfInRAP/
<http://people.apache.org/%7Epamarcelot/ApacheDSConfInRAP/>
You can compare these screenshots to the "real" Rich Client Platform result
with the screenshots on this page :
http://directory.apache.org/studio/screenshots.html


It looks almost the same.

So I think, this can be interesting to look at an administrative application
for Apache DS that could be deploy as an RCP Application but also as a RAP
Application (which could be launched with the server using Jetty).

So, Alex, you're right... "we better embed Jetty into ApacheDS soon"

P-A

Exactly, it is just a matter of target platform, but not all SWT packages
have their identicals in RAT UI, so some code does not compile

At that time it seemed a bit heavy but I guess they must have come a long

Yeah I saw this a while back.  Actually one of their developers showed it to
me at my house.
I ran into him when Niclas Hedhman decided to throw an OSGi party at my
place :).

Anyways, I nearly shat my pants when I first saw what they were doing.  This
was right when the
application for the incubator was filed.  Even then they were showing us how
the same bundles were
used to generate both a fat client UI and an Ajax based web application UI.
At that time they seemed
to simply swap out the SWT libraries under the hood so that even bundles
that worked with SWT
could be used to generate ajax UIs.  Essentially the SWT implementation was
swapped out for a web
based one.

At that time it seemed a bit heavy but I guess they must have come a long
way.  I wonder if it will scale
but then again how many people are going to be banging against an LDAP
administrative UI at the same
time?

Heh we better embed Jetty into ApacheDS soon :).

Yeah, sure !

It seems to be a really good idea !
