I'm looking for a platform that will allow me to run a Java app as/convert a Java app to a web app. Do you guys have an ideas? I previously tried to use AjaxSwing but the support was terrible and even when I got the preview working it ran quirkily.
Are you trying to re-write the Java app as a webapp, or are you hoping to find something that somehow converts it from a desktop GUI to a web interface? I don't know if such a thing is possible. The best suggestion I have is to look at GWT (Google Web Toolkit), but that would also require some rework in the code.
I recommend you to code the website from scratch. It is almost impossible to port from Swing to WebApp. You can re-use some backend code, but presentation code ... not. Source: I am expert Java developer.
