OpenLaszlo is a platform for making Rich Internet Applications. The “production” version of OL (presently at release 3.3, I believe) allows you to compile to (Flash) swf7 or swf 8. OpenLaszlo version 4.0, project name “Legals”, will support, in addition, compilation to DHTML (aka “Ajax”). Legals is in “pre-beta”; an official Beta program will be announced soon. To see how far along the project is, you can go to the OpenLaszlo site and play with a variety of demos that run pretty much equally well in either Flash or Ajax. Sometime next year, probably in the spring, OL version 4.something will support Flash 9.
Now here comes an announcement of Project Orbit from Sun Mircosystems, to compile OpenLaszlo apps to Java Mobile Edition. Java ME runs on *billions* of devices, notably cell phones.
I work for Laszlo Systems, Inc, the creator and main supporter of OpenLaszlo. I’m responsible for all the OL documentation. It’s a good job. It’s cool to see the whole idea of “write once run everywhere” really starting to become real. Flash 9 which is based on the next version of ECMAscript/JavaScript, is different enough from earlier versions of Flash that it really constitutes a separate runtime. For those of you keeping score, that means that OL has active projects underway to support four distinct runtimes: Flash 7/8, Flash 9, DHTML (Ajax), and Java. Yes, there will be locally distinct differences in some applicaitons depending on the target runtime. But in general, OpenLaszlo applications truly are runtime-agnostic.
It’s also fun see the OL community growing and becoming real. There are now several developers who have “commit” priveliges to the code base who do not work for Laszlo Systems — including developers from Europe and Japan.
Note that OL is developed completely in the open. Anybody can sign up for the mailing lists on which we discuss architecture and implementation. The “nightly build,” which incorporates each successive day’s work, is avaible for free download. In other words, even though “Legals”, our Ajax port, is not yet in an official Beta program, you can still get your hands on the code if you’re the kind of person who likes to read code to see what’s going on.
