Eclipse RAP 1.0 Comes

Posted on October 15, 2007 by Zhou Renjian

Eclipse RAP team has just released its 1.0.

The RAP project enables developers to build rich, Ajax-enabled Web applications by using the Eclipse development model, plug-ins with the well known Eclipse workbench extenstion points, JFace, and a widget toolkit with SWT API (using qooxdoo for the client-side presentation). The project has graduated from incubation and released its 1.0 release.

In fact, Eclipse RAP and Java2Script have a lot in common. Both are based on SWT API and have goals to provide ways for developers to share the same base of code for products that deploy to the web and the desktop. Here is overview of Eclipse RAP. And you can also read Java2Script’s overview for comparisons.

And you can also check out Eclipse RAP demo to get more details. It’s interesting to see that RAP and Java2Script have 2 very similar demos: RAP’s RWT Control Demo and Java2Script’s SWT Control Examples.

Java2Script Gtalk on Opera Mini 4

Posted on October 13, 2007 by Zhou Renjian

It’s amazing to see that Java2Script’s Google Talk get run on Opera Mini 4 inside a mobile phone.

Here is Opera Mini 4’s simulator for you to test its CSS/JavaScript/AJAX compatibilities:

Here are screenshots:

Zoom in to get a clear look:

Login and connect:

Now we are in:

Zoom in to get a clear look on friend list:

But Java2Script Gtalk does not get run as totally correct. It fails to maintain normal connection back to Gtalk proxy server. So after a few seconds, the proxy server closes the connection. Maybe Java2Script Gtalk may fix this problem later. And also I think Opera Mini team may improve its AJAX supports in the near future so nothing need to be modified.
