I am a Mac "fan boy" and Steve idolizer, and IntelliJ loyalist. Now that we
got that out of the way...elbow. I don't use Eclipse and I have not take a
serious look at it since the days when it did not run correctly on a Mac.
Does it now? Prompted by the rabid enthusiasm of a colleague, I downloaded
the latest release to check out RAP.
I've been sitting in this chair for the 4 hours gleaming with enthusiasm and
noxious intrigue. I think this is the project I have been looking for coming
over from the Lazlo cult. Please check my coat, I'm going to make myself at
home.
As I was recently introduced to RAP (and reintroduced the Eclipse platform
in general) I have a lot courting to do the platform. I'm struggling to
understand RAP's relationship to, and interoperability with, other resident
JEE components, though I must say the niche or shall as grand "vista" that
is fills with glorious Web 2.0 potential good ness is overwhelming evident.
The ecosystem has a new 800 pound gorilla on the prowl.
A few questions if thou unknown will indulge me:
[1] Given RAP applications execute primarily on server side and in part on
the client side, what portion of the application actually lives where once
coded and rendered useful by RWT?
[2] How susceptible are portions of the client side code to state tampering
and possible allowance of request spoofing by design? What's the scoop on
security?
[3] Can RAP applications communicate with the host application server
possibly received resource injection or making use of other JEE server
features?
[4] Can RAP applications live in JSP pages as embedded components, whether
autonomous or collaboratively, or safely obtain a reference to the servlet
context?
[5] Scrap the work bench concept. It's too desk top centric (but I guess
that's the point). What if there was RAP portal-like architecture? Something
like the Eclipse Enterprise Portal Container. I saw something similar which
was called the Rich Server Platform. The notion of plug-ins in web
applications is very exciting to me. I've ate dinner sketching out the
possibilities of RAP portal container. Are there any thoughts out there
about RAP interoperability with JSR-168/WSRP containers and the
possibilities?
[6] Has anyone else considered the possibilities of implementing RWT as XUL,
Adobe Flex, or Microsoft XAML? I am particularly interested in implementing
the Flex layer. RAP has the function. Now it needs the form, ergo a more
robust themes API that can bring applications alive and allow them to look
less like an IDE or Windows 2000 artifact (I've had my good eye on SWT
Cocoa). Haw does RAP compare and fair to other so called Web 2'oh frameworks
and other AJAX lime-lights like Spry?
Thanks in advance for your input and advice. I look forward to contributing.
Regards,
Rafael

RAP applications are in fact server-application with a thin client
front-end. The thin client uses rich components and AJAX to provide a good
user experience. This means that data models, program logic etc. resides on
the server. As the requests between client and server transfer the UI-state
changes only, the content-length of those requests are generally very small.
The combination of the fast response time with the rich javascript widgets
is the base concept the RAP web-workbench relies build on.

We addressed this subject shortly before the 1.0 release. The outcome was
that the RAP architecture itself avoids a lot of the known security problems
of javascript based applications. So there were only a few additional lines
of code necessary to close the rest. I don't want to pretend to be an expert
on this, therefore I leave it with this superficial answer.

Sorry, I don't quite understand the question. Maybe there's a
misunderstanding that RAP applications provide some kind of client side
autonomy, which is not the case.

In principle it is possible to embbed a RAP application in a JSP-page but I
think the usefulness of this approach is limited. You could think of it as
an applet running in a web-page. The other way around - embedding JSP pages
into RAP applications - is the more common approach. Communication between
RAP and JSP can be achieved using the common infrastructure of the web
application (servlet-context, sessions etc.).

The workbench concept is one possibility using the technology. You can use
RAP and the bundle mechanism (plug-ins) provided by the Equinox
infrastructure without workbench. It is even possible running RWT
standalone. Regarding RAP and Portlets you may have a look at
http://dev.eclipse.org/newslists/news.eclipse.technology.rap /msg00021.html.

Here are some thoughts on this:
