Hi Jacques,
These are few off the top of my head:
Pros:
1. Rich and responsive UI similar to the desktop applications.
2. Programming model similar to the desktop application and no need to
deal with request, response, URLs etc.
3. Single sourcing that is application written for web can run on
desktop and vice-versa with minimal or no changes to the code.
4. Applications can come and go on they fly without restarting the
server as RAP is also based on OSGi runtime.
5. Applications can be developed as small plug-ins. Plug-ins can be
written by third parties who do not have access to the source code of
current application.
Cons:
1. Steep learning curve for those who are not familiar with SWT/JFace
programming.
2. In contrast to other technology, scaling the RAP application will
need more server side resources as most client side events are relayed
to the server.
3. Comparatively new to the market. However, it is going to be integral
part of the Eclipse 4 release and it may become more popular than other
similar technologies.

Raj

Thanks Chris and Raj,
I remember now, Raj, that you already spoke about RAP.
I think I will have a look, but have you alreay any opinion about pros
and cons?

Hi Jacques,
Yes it is Rich Ajax Platform (RAP). RAP enabled Eclipse based
applications to run on web without or very minimal changes. This is
called single sourcing that is write your applications once and run
them either as web or desktop application. Programming model of RAP
is same as Eclipse Plugin-ins.
Thanks,
Raj

Hi Jacques, I think for the client Raj is using RAP from eclipse - the
following link describes it in a few words: http://www.eclipse.org/rap

Hi Raj,
Could you please explain more the client-side section? Did you use
something GWT, or?
Thanks

Subject: Re: OSGi based OFBiz framework
Hi BJ,
Purpose of the demo is to show how to:
Service side
-------------
1. Run OFBiz inside a OFBiz container using OSGi based runtime
such as
Apache Felix and Eclipse Equinox and reap the benefits of OSGi.
You can find
about OSGi benefits at this URL http://www.osgi.org/About/WhyOSGi.
2. Make OFBiz more modular that is separating the framework (entity
engine, service engine etc) from the applications.
3. Provide remoting capabilities to OFBiz services using OSGi remote
services.
4. Use other technologies such as JPA along with OGBiz entity engine.
Client side
-----------
1. Create Rich applications with the similar capabilities and ease
of use
of Desktop based applications.
2. Run the single client application either on web or desktop with
minimal
or no changes to the code.
3. Plug-in based development of application that is, to add new
functionality to the application, you do not need access to source
code. You
can simply create new bundles/plug-ins and they add to the existing
application, same as Eclipse Plug-ins.
To get the feel of the application, try double clicking on the
examples in
the left pane. Try editing the example in the right pane. See how
changes
are populated from one pane to another even without saving the
application.
Try changing the column width, you will get the same feel as a
desktop
application. Try emptying the name field and see the validation
decoration
with a tool tip.

Raj

Those who want to peek into running example without installing the
application, here is the link:

Hi,
I have been working on OSGi and OFBiz integration for a while.
I could
successfully, run the OFBiz framework (entity engine and service
engine) as OSGi services. With this integration it is possible
to run
Framework only OFBiz and use the OFBiz service engine for non form
widget applications (e.g. GWT, JSF etc). This should be
interesting
for people wanting to use the service engine and entity engine.
For my experiment I have Eclipse RAP
(http://www.eclipse.org/rap) for
presentation layer and ported the part of Example application.
My RAP
example application is using OFBiz entity engine to fetch some
of the
data and service engine to create and update the examples.
I have uploaded the installable bundle at SF and it is
available at
https://sourceforge.net/projects/ofbiz-osgi/files/osgi-ofbiz.tar.bz2/download
Requirements:
Platform - Current distribution works only on Linux (x86_64)
systems.
This restriction is due to the executable including in the
distribution. It should be possible to run it using java -jar
command
but it will need some configuration which is not ready yet.
Database - PostgreSQL DB server with database named 'ofbiz' and
owned
by user 'ofbiz' and password 'ofbiz'. It is possible to use other
databases but there are not JDBC driver bundles yet. Database
server
must be running on localhost. It is possible to use the server
running
on other hosts but it will need the change in entityengine.xml.
Demo data - OFBiz demo data loaded in the database as I am using
example and other related entities in the demo application.
Install& Run:
1. Extract the tar achieve on your hard disk.
2. Change to osgi-ofbiz folder.
3. Execute ./ofbiz -console.
4. point your browser to
http://localhost:8080/demo?startup=example
Example application is written using Eclipse RAP. On application
startup, you should see a table with existing examples in the left
pane. Try changing the length of the columns.
Double clicking on a example should open it in the right pane
editor.
Changing a field value in the editor should show instantly in the
right left panel (table view). Try emptying the name field in the
editor and it should show you a validation decorator. Hovering
mouse
on decorator should show you the validation message. As soon as
you
change any field, an asterisk (*) should appear next to the
title on
editor pane. Trying closing the editor and you should see a
dialog box
prompting to save before closing. Save the example by clicking
on save
button on toolbar.
3. Try creating an new example. Save the example and you should
see
the newly added example in the left pane without browser refresh.
Should you need any further help, feel free to ask me. Look
forward to
your feedback.
Regards,
Raj
