Introduce New GWT UI/Graph Framework - Trufun WebRCP

http://code.google.com/p/trufun-webrcp/

Trufun WebRCP：the GWT framework with completely open source based on
html5 technology, is used to transplant eclipse RCP to GWT WEB.

On the basis of WebRCP, developer can develop GWT application with
eclipse SDK API. At present WebRCP has already been succeeded in
transplanting to GWT platform from eclipse user's interface
SWT,JFace,UI, RCP, excellent Graphical editing framework Eclipse GEF,
model editing framework Eclipse EMF and Eclipse UML2 etc..
Developer ,with a few modification, can switch the applications
developed by eclipse SWT or eclipse RCP to GWT, then turns them into
WEB program.

Users can transplant applications developed by the eclipse platform to
the WEB on the basis of webrcp, also may develop the new WEB
applications based on the API of powerful eclipse platform. The
typical case is like new WEB vectorgraph application developed on the
base of GEF API and EMF/UML 2 API, such as flow chart,engineering
drawing,UML modeling,GIS .

All the main current browsers have already been provided with the
html5 as the support these days, so webrcp, on the basis of html5
technology, can run not only on PC, but also on the removable
equipment providing HTML5 browser as mobile phone and tablet PC .

Compared with the Eclipse RAP transplanting RCP to WEB, RCP can be
transplanted to WEB almost without the modification , this is the
advantage of Eclipse RAP.But the disadvantage is that it can't be
helped for client interaction without server like Word Processing and
Drawing etc..On the contrary, Trufun WebRCP needs a bit of
modification when switching RCP due to the restriction of GWT. But
it's more suitable for drawing and word processing and so on ,which
are the applications without server interaction,even with no server,
only a WEB page can do the drawing, storage and read for local
computer. These are characterized by local applications to develop
tablet PC and mobile phone by html5. In additon, another important
differece is WEBRCP is based on the HTML5 technology, therefore RAP is
unable to do it at present if adopting the character of HTML5 like
canvas and video so on.

As the typical application, the WEB drawing frame ,which is provided
with GEF based on webrcp, is compared with the existing WEB drawing
frame as follows:
Jgraph: Mxgraph is provided with Jgraph. On the one hand, mxgraph must
be developed with javascript ,which is too inconvenient on development
and debugging compared with java; On the other hand, its API has a big
difference from mature eclipse GEF. Moreover, Without EMF as the
support, the persistence of graphic data is also the big problem.
Flash/silverlight: First, Flash/silverlight requires users to download
relevant plugin. Second, Flash/silverlight doesn't have API as
powerful and mature as GEF/EMF has.
Applet/javafx: One side, users are required to download relevant
software. Another side is the big problem of compatibility.
