OpenLaszlo - Better than Ajax and Flex ?!
For those of you who love the user experience provided by Ajax and Flex and are debating on pros and cons of the two, here is an open source alternative which may be of great interest.
OpenLaszlo is a Web 2.0 open-source alternative to Flex and sometimes Ajax (even though it is heavily based on the Ajax platform). It is a very cost effective approach to building high end, powerful, cinematic web applications. It can be developed by using just XML and JavaScript. OpenLaszlo can be deployed from any HTTP Web server in SOLO mode, or from a J2EE application server or Java servlet container running the OpenLaszlo Server under Linux, UNIX, Windows or Mac OS X. The output is displayed in any Web browser enabled with the Flash 6 Player or above. And above all it is absolutely free!
Currently, OpenLaszlo can deploy applications running Flash, and DHTML support is expected by the end of 2006. OpenLaszlo is being extended to give developers the option to run applications using Flash or DHTML, an open standard built into most browsers. Future extensions include embedded runtimes in consumer devices, such as mobile phones and TV set-tops.
OpenLaszlo LZX is a declarative XML markup language with embedded JavaScript designed expressly for advanced Web applications. Its syntax is familiar to developers experienced with JavaScript, HTML and XML, and provides advanced language features such as animation, layout, drawing, data binding, and server communication (persistent connections, SOAP, XML-RPC and XMLHttpRequest) to create an extraordinarily rich user experience.
OpenLaszlo "Legals"
"Legals" is an OpenLaszlo project to provide a single application environment that supports multiple deployment runtimes. OpenLaszlo 3.x supports Flash 7 and 8 now, but Legals will extend that reach to include DHTML as well as Flash 9.
Demos
A list of rich internet applications designed using Open Laszlo is available here which includes amazon store, calendar, weather and many more.

Although I am very intrigued by this technology, I have not tried my hands on OpenLaszlo yet. I am interested in knowing about experiences from those who have developed applications using OpenLaszlo and their take on it. Please comment below.

We used it one of our Enterprise Apps. It's quite useful for charting, dynamic updates (AJAX style) etc.
The only problem we faced was single sign-on (using jboss/tomcat) was not working over SSL in IE (worked perfectly in firefox). So in IE we had to load the swf over http and rest over https.
That was a IE problem though.
useful information blog,very good content.
OpenLaszlo is much better than Flex 2.0 for many reasons.
1. it's free.
2. Open source.
3. With OpenLaszlo Legals you make output of your code from Flash7 to Flash9 or as Ajax without changing a single line of your code.
Thank you,

This is a very old blog entry, but i'd still like to comment the last poster. Now I have not made up my mind wheter to go with OpenLaszlo or Flex, but something being free or open source does not in my view make it any way BETTER. I define 'better' being more efficient, easy-to-use, reliable, scalable etc.
