[e4-dev] Java2Script's SWT in JavaScript
|
Hi All,
I am Zhou Renjian, Java2Script (
http://j2s.sourceforge.net/ ) project initial contributor.
I am new with E4 and SWT/BE. After scanning through this mail list,
"running desktop UI components in web environments" really interests
me. I also learn from blog post that the goal of SWT/BE may be "SWT
widgets cross compiled to Flex or Dojo". And I agree with "this is one important reuse
element of Eclipse being able to move to the web". I think
Java2Script project may help for such a goal.
Java2Script (J2S) provides an Eclipse Java to _javascript_ compiler plugin and an implementation of _javascript_ version of Eclipse Standard Widget Toolkit (SWT) with other common utilities, such as java.lang.* and java.util.*. You can convert your SWT-base Rich Client Platform (RCP) into Rich Internet Application (RIA) by Java2Script Pacemaker.
Java2Script, similar to GWT, provides Java to _javascript_ compiler and a client side UI widget library. Instead of providing a new UI library, Java2Scriprt supports SWT APIs from its starting point. So all existed SWT applications may be compiled by Java2Script and ran in modern browsers without or with little source modifications. If source modifications are needed, we provide @j2s* Javadoc and @J2S* annotation to keep native Java desktop version and web browser version compatiable. So one copy of *.java supports both desktop and web.
Java2Script, started from 2005, already supports most of SWT controls. And JFace support is in its early stage. Please check out the demo:
http://demo.java2script.org/ or
http://demo.java2script.org/controls/ for more information. Java2Script's SWT is not optimized enough, and I must admit that it is a little slow in loading and running.
And WeBuzz.IM (
http://webuzz.im/ ) is a running web IM service based on Java2Script technology and its _javascript_ SWT library. You can check its screenshot of web browser version :

I know that SWT for Dojo may be under development. Some of these efforts may be overlapping with what J2S had already done for a long time. So this mail list may be interested in this Java2Script SWT implementation. And it should be a good idea for us to collaborate together.
BTW: As Java2Script is licensed under EPL 1.0, if it can help SWT/BE, it is OK for us to contribute the sources to SWT/BE.
Regards,
Zhou Renjian
