No, no, no Arne! I meant what I said: -

But the Plug-In does! Take the following list that I dynamically inject
into the DOM at run-time: -
var appletParams = [{"name":"archive",
"value":archiveName },
{"name":"codebase", "value":codeBase
},
{"name":"code", "value":className
},
{"name":"java_version", "value":"1.7*"
},
{"name":"mayscript", "value":"true"
},
{"name":"scriptable", "value":"true"
},
{"name":"codebase_lookup", "value":"false"
},
{"name":"java_status_events","value":"true"
},
{"name":"permissions", "value":"sandbox"
},
{"name":"cache_option", "value":"no"
},
{"name":"APPLICATION",
"value":application },
{"name":"PORT", "value":port
},
{"name":"MAXBUF", "value":maxBuf
},
{"name":"HOSTCHARSET",
"value":this.hostCharSet },
{"name":"SSLREQD",
"value":this.sslReqd },
{"name":"HANDSHAKE",
"value":this.handshake },
{"name":"IDLETIMEOUT",
"value":this.idleTimeout },
{"name":"TABMAILBOXSIZE",
"value":this.tabMailboxSize},
{"name":"VERBOSITY",
"value":this.verbosity }];
I think you'll find, and take the time to acknowledge, that only those
in UPPERCASE are of no interest to the JPI?

Please PLEASE spend the time to read the ORACLE nee SUN documentation at: -
http://www.oracle.com/technetwork/java/javase/index-141751.html#MECHANISMS
It has been my experience (although Oracle seems to require an OTN
account to download older JREs these days, so I can’t re-confirm) that: -
1) If you have Java 6 and 7 on a system and I select 1.6 with my OBJECT
tag then I will get a Java 6 JVM
2) If I have only Java 6 on my system and I request, nay mandate, Java 7
then the Plug-in says “What’s the big deal? Java’s Java! Just take 6 and
see how you get on”.
No errors; no nothing :-(
Even though the above link clearly states that an auto-download of the
desired Java version can be triggered by the use of the “java_version”
PARAM, I’m happy that it doesn’t and just fails but I insist it not fail
silently. Is this really too much to ask from a vendor?
Oracle are still publishing misleading Tag bullshit like this: -
http://docs.oracle.com/javase/6/docs/technotes/guides/plugin/developer_guide/using_tags.html

JNLP relies on the complete crap of strategies that I've paraphrased
from http://ORACLE/LarryTheLoungeLizard/DeployShit.js as seen below.
A simple question: - "Why can't Java provide the advertised
functionality since 'The New Java Plug-In' circa 6.10?" And if it can't
why can't you stop failing silently you incompetent twats?

I think you should read more out of your comfort zone. For example: -

50 shades of Larry's ego :-(

PS. (Why the fuck do I have to do this?) As gleaned from the warped mind
of someone Larry chooses to employ: -
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
function isJavaInstalled(version)
{
var compare;
if (Object.prototype.toString.call(version) == '[object Array]') {
var versionList = version;

return a == b;
}
} else {
var versionList = [version];
compare = function(a,b) {
return a >= b; // Bad luck for IE. Use [7,8,9]?
}
}
if (window.ActiveXObject) {
for (var i=0; i<versionList.length; i++) {
try {
var fred = new ActiveXObject('JavaWebStart.isInstalled.1.' +
versionList[i] + '.0.0');
return true;
} catch (err) {}
}
}
if (navigator.mimeTypes) { // Opera Mime Types don't de-install
for (var i=0; i<versionList.length; i++) {
for (var j = 0; j<navigator.mimeTypes.length; j++) {
if
(navigator.mimeTypes[j].type.indexOf('/x-java-applet;jpi-version') != -1) {
var dotArray = navigator.mimeTypes[j].type.split('.');
try {
if (dotArray.length > 1 &&
compare(parseInt(dotArray[1].match("[1-9]*")), versionList[i])) {
return true;
}
} catch (err) {}
}
}
}
}
return false;
}
function load() {
alert(isJavaInstalled([5,6]));
}
