Java - Critical Patch Released
Krishean:
DO NOT USE JavaRa it will break JavaScript in IE (and any embedded browsers that applications use) by deleting registry keys unrelated to Java. It goes after some of the things in the registry that just have java in the name, but are actually part of JavaScript. I found this out the hard way. the specific keys are:
HKCR\JavaScript
HKCR\JavaScript Author
HKCR\JavaScript1.1
HKCR\JavaScript1.1 Author
HKCR\JavaScript1.2
HKCR\JavaScript1.2 Author
Looks like this has been fixed since then: http://forums.lunarsoft.net/topic/4984-major-bug-in-javara-116-now-fixed/
Krishean:
I have a batch script that attempts to purge java from your system, and cleanly install whatever version you specify, just place the scripts in the same directory as the JRE installers downloaded from here: http://www.oracle.com/technetwork/java/javase/downloads/index.html and update the variables at the top to match whatever version you are installing. This also works when installing from network shares.

40hz, have you used JavaRa? It sounds useful, but I'd like to know that it won't create problems (e.g., wrong removals from the Registry). I'd feel more comfortable installing and using it if I knew that you and/or other DC folks had some good experiences with it. Perhaps I should change my username from cyberdiva to Nervous Nelly :(

@CD- Nope. Maybe Smart Lady but certainly not Nervous Nelly. ;D
And yes, I use it. I don't recommend anything I don't have direct experience with. If I've only read or heard about something - and I'm passing it on as an FYI - I'll always say so. :Thmbsup:
The new version of JavaRa uses a database and an updater to stay on top of what Oracle gets up to with new Java releases. I haven't had any problems using it either on my own systems or those of my clients.
But it's mostly a convenience tool. You could always just uninstall any old versions of the JRE through Windows' own add/remove programs control panel - and then download and install the newest version from Oracle.
Where JavaRa really does sing, however, is when the JRE balks at being uninstalled. Or if fails to uninstall cleanly - as some versions occasionally do on some machines. JavaRa has the option to scrub out all things JRE, leaving you with a clean slate to put a fresh copy on.
It's like what's been said about tennis racquets - you don't often need one... but when you do, there's really no direct substitute.
Although now that Krishean has been kind enough to share that script I guess that isn't the case any more. :)

@ Krishean - thx for sharing that. Looks useful. And an interesting script to read through too. :Thmbsup:
cyberdiva:
Thanks very much, Krishean and 40hz. I've decided that for now, I don't need JavaRa. However, I'm glad to know about your script, Krishean.
