If you try to view a page with JavaFX applet on an iPhone you'll get a blocking message saying that you need to install java, and will be unconditionally redirected to java.com website. It is impossible to cancel or work around this. This appears to be a problem with dtfx.js .

To test, go to http://weblogs.java.net/blog/campbell/ .

Presumably you'll run into the same problem if say java is disabled in the browser or there' s no java plugin for a particular browser.
