#4 Detect Java and offer install

[Marc Laporte]

jCapture requires JRE7 now requires JRE6, but as of 2012-06-23, it doesn't offer to install if it's not present.

As of 2012-05-18, it doesn't properly detect the version. When attempting to use jCpature with JRE6, nothing happens (no error message)

Pavel explained: "I tried to use "the new way" to define the applet tag using JavaScript, as described here http://docs.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html, jcapture.jnlp is the "remnant" of those efforts. It didn't work. I guess the reason is that applet.php is loaded by ajax and deployJava.js did not get executed. I didn't want to mess with DokuWiki internals to adjust sack to evaluate scripts on load and abandoned my efforts."

The integration in Tiki doesn't use applet.php as it was too specific to DokuWiki. In Tiki the applet is defined in templates/jcapture/capture.tpl and it uses an < object > tag to embed it, which is supposedly the html5 valid way of doing this (but does still seem very fragile).
I'll recheck and see if i can add a download URI as a parameter to that...

The Screensharing applet for BigBlueButton is a good example for how to make sure user has Java installed and up to date.

"This fixes the Java version detection in the
deskshare applet so that desktop sharing will continue to work with
newer Java updates (including Java 7 update 65 and Java 8)."
