RE: [rt-pmc] FW: FW: RT whitepaper check in
|
Scott,
Thanks for the feedback.
For point #1 if you want to send me some word, I am sure it would be useful.
For point #2, how does your support for the OSGi EE compare to the recently announced Gemini project?
For point #3, I agree Equinox can be run on a server with no UI. However, typically when people refer to a Web App they mean applications with render in a browser, hence the focus on RAP.
I agree with point #4 we need to highlight upfront the component nature of EclipseRT.

Hi Ian,
Here are some comments about this white paper.
WRT ECF specifically...first, in the SOA section, you say this about ECF:
"In addition to the Swordfish project, the Eclipse Communications
Framework (ECF) contains
libraries that provide asynchronous point-to-point and
publish-and-subscribe messaging.
Along with the Jetty web server, ECF can be used to create light-weight
SOA or RESTful
end-points and consumers when a more comprehensive SOA framework would
be overkill.
[tk: is this true about ECF?]"
1) The parenthetical remark at the end about ECF is true...i.e. ECF can
indeed be used to create light-weight endpoints...BUT I think it's not a
good characterization of either ECF or Swordfish to present ECF as
somehow a 'smaller/less comprehensive soa framework than Swordfish'. In
general, I would prefer that the presentation of ECF be given without
any reference to Swordfish, as it not either a part of nor a subset of
Swordfish. ECF is a modular set of frameworks to support inter-process
communication...and it provides a number of options for doing so...e.g.
APIs for building RESTful remote services, APIs for discovering and
accessing remote services, APIs for building services based upon
asynchronous messaging patterns, and other remote services. If you or
others want additional prose/detail or explanation for this let me know
and I will provide it. Also...given the use-case-driven nature of
things, ECF can point to a number of use cases...if these are desired
(e.g. the recent EclipseRT in Austin or others that I can point to).
2) I also wish to say about 'Enterprise Applications': although ECF is
indeed smaller/simpler/lighter-weight than most 'enterprise frameworks',
we have been/are already implementing the OSGi R4.2 standards that have
come out of the Enterprise Experts (EE) group (i.e. what was
RFC119/distributd OSGi and is now called 'remote services' in the OSGI
4.2 final spec). So ECF's work on the OSGI 4.2 standards is very
relevant to enterprise (at least according to the OSGi EE).
A couple more general comments about the document i.e. not specifically
about ECF:
3) I find it somewhat strange that under 'Web Applications' that
Equinox-on-the-web-server is not presented more obviously. Running
Equinox on the server (with or without RAP...or in fact with or without
any user interface), is something many people are already doing...in
commercial app servers, cloud computing, server-based products, as well
as internal enterprise applications, etc. There are many
servers/services that have little or no UI at all (or have very
different clients than PCs/web UIs...e.g. toast) that can/could/will
benefit from EclipseRT-on-web-servers...and for me this doesn't come
through clearly in this document.
4) Another point is that although Jetty is a fine web server, I think it
should be made clear that Equinox/OSGi can be used with or without Jetty
(e.g. http://www.eclipse.org/equinox/server/). The more general point
is that *all* of the projects/frameworks within the EclipseRT are
modular by their being based upon OSGi/Equinox...and are therefore
usable either together, separately, or perhaps in pieces (e.g. using
only REST support in ECF or just discovery, or only parts of p2).
Although this is discussed at in the existing document (i.e. the last
paragraph), I think the modular structure of the EclipseRT projects
should be emphasized up front (perhaps with a graphic?), as the
'take/use only what you need' aspect is very powerful, and, I believe,
potentially very attractive to application developers of all kinds (i.e.
web server/web apps, desktop applications, embedded system dev, etc).
