We want to change our current framework to the RAP framework. I want to know if RAP is stable/safe enough for business use.

I hope someone can help me.

Hi,

we use RAP for many years now and have build very complex business
applications using this technology [1].

For me there are two big advantages compared to other web frameworks:
- Very rich desktop like UI
- Good modularity through OSGi on the server side

Of course there are some drawbacks as a poor performance on older
Internet Explorer versions (most JS-frameworks have problems here) or on
Netbooks. Plus the fact that a RAP app cannot run in a single Browser
instance on multiple tabs simultaneously.

If you have more concrete questions you'll surely get an answer in this
newsgroup :-)

Regards,
Stefan.

Hi,

from our point of view RAP is stable/safe enough for business use. We use it ourself since one of the earliest versions of RAP. At the beginning there have been a lot of Bugs or missing Features, but nowadays it is stable and most of RCP Code works in RAP.

The advantages that Stefan posted a really a great thing to use for a web application.

Regards,
Markus Krüger

We use RAP in over 20 production instances for one of our products and
more products and customers are coming.
The parts we use (jface + rwt) we consider as very stable. Indeed we
rarely faced any issues (with RAP ;) ) and in case of probles the
RAP-developers are very fast to help and answer in the newsgroups.

With its customizable widgets we could also add features, which are not
present in the official releases (integration of custom authentification
and seamless integration of word-processors).
We run mostly on IE6 sometimes even with HTTPs - so the most worse
scenario you can think of :)

I'm really happy that most of our developers don't need to know anything
of HTML and Javascript. Just the ones who needed to write the Widgets.

For those who use this, what does your deployment environment look like? Are you using the traditional J2EE Servlet container or using an OSGi based app server such as Jonas or dm Server? What are your recommendations based on your experience?

Thanks for your input.

We use Tomcat 6 as our Servlet Container, running RAP, Spring and our
O/R-Mapper (still JDO) all at once.
To make things simple for us, we just use RWT + JFace parts standalone
(see the wiki or this forum for more information), so no OSGI is involved
here.

This decision was made, because we didn't need/want the classic workbench
layout (though it heavily improved with the latest version).
Also we wanted to retain all options to reduce the memory footprint of a
user-session, which we were afraid we couldn't do when using the
workbench.
Finally normal product development is hard enough even without OSGI - as
for now I don't see it would solve me more problems then it brings
(JPA/JDO and database-drivers don't like OSGI much).

Regards
Stefan

There was a demo at ESE about EclipseLink [1] where they showed that
things improved in this area. However, I haven't tested it by myself and
there still seems to be some kind of magic involved (as specific
manifest headers).

Stefan.

I guess your developers have the choice between VI and EMacs?
