My "Solar" accounts program won't run without "legacy Java SE6 runtime" since I upgraded my iMac desktop to OS x Yosemite but I can't download it, nothing happens when you click on the link to apple support

What has been released to install as a security update? I seem to be clicking on one web link which takes me to another and nothing to actually install. Typical Apple. Really wish I hadn't bought this MacCrap Air - I do miss my PC.

I was running java 1.6.0_33 on my Mac Lion and later I installed java 1.7.0_05. Now in my Java preferences I see both the Java SE available.Now my problem is when I enable Java 7(& select Enable applet plug-in and Web start applications), my JNLP file doesn't run with java web start, from Safari as well as Firefox. When I try running the jnlp using Open With option and selecting Java Web Start present in /System/Library/CoreServices, nothing happens.
When I try running the JNLP file from Terminal suing command /System/Library/CoreServices/Java Web Start.app/Contents/MacOS/Java Web Start xyz.jnlp I get following error
Java Web Start splash screen process exiting... Can not find message file : No such file or directory.

I made a Java applet with Xcode 3.2 and i load it to firefox or Safari(Yeah i've updated my java)and for example
i made a HELLO WORLD simple applet to be in black color letters, then compiled and yeah it worked but then i redid it for the letters to be red.. and they kept being black..no matter how many times i recompiled the applet.
And yeah the HTML is pointing to the correct class file. Also, If if i add a Thread and implement runnable.. then nothing shows up in the canvas.
And also, what ever happened with the appletviewer application? We don't have that anymore.
now the only way to run applets is through a web browser. Is java applet developement in 10.6 really over?

Since the flurry of 2012 updates, Java is completely broken on my Mac Pro. Java dependent apps don't start and Apple Support says to enable the apps in Java Preferences. Nice idea, but Java Preferences WILL NOT LAUNCH either. There were plenty of tools to address flashback and they DID NOT break normal day to day operations.I downloaded the package from support to try a re-installation, but it says "A newer version of Java is already installed" and offers me the option to Close. No reinstall, nothing. Apple support is at it's usual level of service on this issue, completely INVISIBLE.

I am brand new to Mac (I got a G4 laptop in trade to replace a dead windows desktop).I am trying to install Limewire and it tells me that I cannot: "could not launch application because it requires a version of Java that is not installed". It goes on to acknowledge that it can see everything up to 1.5...but that I need 1.6.
So, I go to Software Update and make sure that I have 1.6. It tells me that there are no new updates, that my computer is up to date.I think I recall being told that I am running Leopard on this laptop.If java 1.6 is available, and I do not have it, and my computer tells me that there are no new updates that my computer needs and will not automatically grab java 1.6, yet I need it to install anapplication....what are my options?
I am having problem with post processing a simulation. Every time I hit the "plot parameter" button within the software I get the same error. Opening the file on a windows machine works perfectly fine, therefore I have tried updating the Java through "Software update" and still no luck.
Here are the error details:

I'm using a PC with Windows XP. I'm a private developer. I've written a project in Java and wish to deploy it to other people using email. I've written an Install program (the Main-Class) and successfully packed this in a jar file with the project class files and some data files all as described in the deployment trail in the Java Tutorials. A recipient with a Mac with OS X downloads the jar file and runs it to install the project class files and some data files. The install program then writes an Applescript file (Vocab.scpt shown below) on the Desktop to make starting my downloaded program easier but it doesn't seem to work and I think it may be because the script file is not "executable". Could this be the case? If so, how could I change my install program to make the script file executable or alternatively use some other system to start the downloaded program?
Vocab.scpt:-
# Script to start: Vocab Version: 1.0.0
do shell script "cd /Applications/Vocab; Java Vocab"
Unfortunately I don't have a Mac to experiment with this problem and although I have spent some days on and off trying to find an answer in the mass of information available on Apple's website I can only find small clues here and there to answer my problem (which I would have thought was quite a common one). In Windows a batch file (eg. Vocab.bat) is automatically executable.

I have never installed Java in Lion, I just don't need it, but I noticed in Safari the tick box for 'enable Java' is still ticked, would turning this off disable prompts to install the JRE, or does it not matter? I find it odd that its listed as enabled in Safari even though Lion does not come with Java installed. Any ideas would be appreciated as reducing any attack vector is always a good move, especially at this time.

After installing the latest updates for Java to both 10.7.3 and 10.6.8 the MRTAgent or other files ( /System/Library/LaunchAgents/com.apple.mrt.uiagent.plist and /System/Library/LaunchDaemons/com.apple.mrt.plist did not seem to install. I have installed both through Software Update and also through the stand alone downloads. Various sites have said the above should have installed and there is no evidence on my machine.

So I just decided to install Limewire today. When I installed the newest version I couldn't use it because it required Java 1.6. I learned on the internet that the only way to get around this was to buy Mac Leopard and I'm not about to do that for Limewire. So I thought I would take another route and try to install an older version of Limewire and get around not having Java 1.6 that way. I downloaded Limewire 4.18.8 from this web page: [UR:] . When I open the installer on the computer, I click "Continue' on the first page, I choose to install the application on my hard drive, I get to the Install page, and click "Install." It then tells me: "You cannot continue. There is nothing to install."
