Boris,

OpenLaszlo is primarily a client-side language that binds to server- side data and services. An OpenLaszlo client generally communicates with a server using XML over HTTP. Any server-side technology that can be used to support an Ajax client can also be used to support an OpenLaszlo client. The OpenLaszlo servlet is generally used at development time, and is not part of most OpenLaszlo deployment architectures.

OpenLaszlo 4, which is the first version to support DHTML, is still in its early days. With version 4.1, expected to be released in the next few months, this will be the recommended release for all OpenLaszlo development. Until then we recommend version 3.3.3 for production use, and 4.0.x for early adopters who want to use DHTML support.

DHTML support is currently limited to the most popular browsers, and Opera is not on the "A" list. We support IE6/7, Mozilla 2.x, and Safari 2. Other browsers, including Opera, are considered "B" list browsers (they might work, but are not fully qualified). Generally a given application would be delivered to users either with Flash or with DHTML, not (as in our demos) in both. That is intended to demo the cross-runtime capability rather than as a realistic deployment option.

SVG: there is an experimental version of early support for this, but it is not supported.

I recommend taking a look at this application/white paper for more detail on OpenLaszlo 4 and its role in an end-to-end Web application.

If you are considering OpenLaszlo for a serious application at FedEx, I recommend that you talk with the Laszlo sales team about support and services to help you reach your goal. Please write me directly if you'd like to go down this path.

best,

Hi all,

For a few weeks now I've been lurking around the Ol website and mailinglist. Because of a few inconveniences with the current versions, I haven't started investing any real time in actual development with OL, but I am pretty interested in the whole concept. So please enlighten me on some basic questions.

My biggest current concern is the plugabillity (sp?). Is it possible to use existing (java, .net) libraries in OL projects? One of the big requirements for a possible future project here would be the requirement of LDAP compatibility. Is this possible as of now? Is there a way to make the framework decide whether to use Flash or DHTML? Current examples always seem to make the user make that decision. Why do DHTML applications seem to lock up on Opera (9.23)? I haven't had this experience with any other website but the old MS teamworks websites. Is there any support of SVG in Laszlo already (I know, pretty early, but please check this website:http://www.opera.com/products/ desktop/svg/)?

Thx in advance
