OpenLaszlo 4 Programming Tutorial

Tuesday, May 29th, 2007

OpenLaszlo architect and ultimate insider Adam Wolff has recorded a screencast version of his wonderful OpenLaszlo programming tutorial, available below. Besides being a tour de force of 'vim' text-editing acrobatics, this tutorial demonstrates construction of a simple client-server application in OpenLaszlo 4, and highlights several of the most exciting features of the OL4 release. The video is about 40 minutes long, and best viewed at full resolution. Enjoy!

OpenLaszlo 4.0.2 Released

Thursday, May 17th, 2007

OpenLaszlo 4.0.2 was released to the web today. This is a minor release resolving almost 50 issues reported against OpenLaszlo 4.0.0, and adding a few new features.

Many of the issues addressed in this release were reported by the OpenLaszlo community. Thanks to everyone who took the time to try out OL4 in SWF or DHTML and report your experiences to the mailing list or forum, and a particularly warm thanks to those of you who filed bugs!

As for features, this release contains support for the <html> tag in SWF, so you can embed raw html content inside your OpenLaszlo app from either support runtime. 4.0.2 also includes preliminary support for the SOAP protocol in DHTML.

Full details are available in the Release Notes.

Note that although recommending OL4 for production deployment is our highest priority, we are not yet there with this release. (See here for more.) Your participation, by reporting your OL4 porting experiences, by filing bug reports, and by directly contributing to the platform, will enormously speed up the process.

You may wonder what happened to 4.0.1. Funny story: just as we were putting 4.0.1 to bed, we found a bad regression in the html wrapper code that was causing high CPU load when running the Amazon demo in DHTML. It turned out to be simpler and safer to quietly release 4.0.1 and turn around a 4.0.2 release in 48 hours than to retract 4.0.1 and rebuild it.

Korean PC hardware online shop builds on OpenLaszlo

Wednesday, May 16th, 2007

PCAnn started an open beta phase for the new PC hardware configuration tool implemented with OpenLaszlo. I've always wondered how long it would take to see the first OpenLaszlo application online in Korea, as the country's open source community is a lot smaller than the Japanese one. But Korea has one of the highest penetration rates for high speed internet connections, making it a perfect candidate for rich Internet applications. As more than 70% of the country's internet users are connected with a speed of 22mBit or more application download size doesn't matter in the Korean market.

PCAnn - first Korean OpenLaszlo application

The PCAnn OpenLaszlo application features drag&drop functionality for the wishlist the shopping cart as well as refined filtering functions for the various components on offer. We are excited to see OpenLaszlo adoption in Korea, adding another country to the already long list of countries with OpenLaszlo applications deployed. Congratulations to the PCAnn team!

Sun launches Project Orbit

Thursday, May 10th, 2007

The folks at Sun have been doing a tremendous job getting projects open sourced and released to the community. I'm pleased to announce that Project Orbit has been released by Sun, and is available here:
https://orbit.dev.java.net/

svn repository is here: https://orbit.dev.java.net/source/browse/orbit/

Project Orbit is another runtime for Laszlo that takes the DHTML runtime output and allows it to run in Java ME by emulating the browser DOM. From the main page: 'Project Orbit is the Sun Java ME viewer of Laszlo content. It is a Java ME CDC/Personal Basis application that uses the Rhino engine to run LZX programming language Web 2.0 (AJAX style) applications.'

If you'd like to learn more, I'll be speaking with Hinkmond Wong at JavaOne in San Francisco today at 4:10pm - sorry about the short notice!

There is a lot of low-hanging fruit here - integration with the OpenLaszlo developer's console (a Java radio button), and tighter integration with the OpenLaszlo compiler come to mind. This is a community effort - Sun and OpenLaszlo are relying on folks to pitch in and help move the project forward. If you're looking to contribute to a very cool, forward looking project, here's your chance!
