How do I limit Java Web Start to Java 6 without Java 7 support


HOME » Java

We have a legacy medical application which gets deployed using Java web start however, when user attempts run the application on Internet Explorer it installs Java 7. The application does not support Java 7. So, I have attempted to force the application to use Java 6 Update 30 but have encountered several problems with install Java using the Java ActiveX plugin and Internet Explorer 6. Consistently, it just did not work. The page would assume Java was installed because a plugin developed Microsoft would confuse it.


So, attempt 2. Bypass the plugin and redirect the user to the Java download website, http://java.sun.com/webapps/getjava/BrowserRedirect?host=java.com&am

Converting Java Desktop Application to Web using Applet or Java Web Start
Java

I know that I can convert a Swing application to an Applet or a Java Web Start application. Is it possible to do the same with an application that's not Swing, say Qt using Java?


What I'm really looking for is a UI framework using Java that's as cross-platform as possible and also has a rich set of UI functionality. Being able to run the application as either a desktop or a Web application would be preferable.
