JavaFX or RIA desktop app (on dvd) also available on the web?
Yes, it is possible. If you use JavaFX you will be allowed use multiple deployments. For example, NetBeans 6.7.1 with JavaFX creates several possible deployments from one project. Then you can publish this application on web, DVD, etc. You will need to slightly customize standalone deployment for DVD to be able e.g. start it as autorun if necessary. JavaFX is good choice.
Is it possible to develop an application easily available on the web that also can be distributed on DVD (installer or started from the dvd)?
For the moment, we use static html (frameset!) pages (generated by xml files), with one difference: pdf's are only on the DVD version, the web version only shows a preview of these files.
Can this be done with JavaFX, OpenLaszlo or are there better options?
(for example: turbogears, and using tg2exe for DVD version)
