Java 7.13 won't allow a program to run

I have d/loaded Java 7.13.

After discovering a website wont run, I followed the directions to uninstall and reactivate Java 6 (from this support site using Unix commands). However, when I return to try running the website again - it still wont work.

I do not have a Java button in the System Preferences any longer.

I did use CleanUninstall to remove the Java Applet Plugin (as well as some other Java related items it found which I have no idea what they were)

I cant run any Java "commands" in terminal like "java-version" - the system says command not found

I can get a list of Java commands however if I simply type Java into the terminal window.

I had a similar issue several months ago with the same web site and the "revert to Java 6" worked, but not this time. When I try the website now, after uninstalling Java 7, the browser prompts me to download Java 7 - which of course if a complete 360.

Im on a Mac mini, 10.8.2

Any thoughts? Thanks in advance

I am also unable to get Java Applets to run using the latest versions of Java 7 (update 13) and Mountain Lion (10.8.2). Is anybody out there able to use applets with this combination? Please. People are getting desparate here.

With regard to running Java from the command line, I can be of help. The listing below represent some key directories on my system. (I'm not quite sure how you are distinguishing terminal like commands from actually typing commands in the terminal window.)

The simplest way to get the java commands to work is to modify your PATH environmental variable (in .profile) so that the current Java binary directory (/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home/bin) comes before /usr/bin

The which command is very useful here

which java

will tell you what directory it is using for the java command

With regard to Java 6, my understanding is that Apple has disabled applet support in Java 6.

The java commands in /usr/bin have to be changed because Oracle is using a different directory structure than Apple did. What was Commands in the apple version is Contents/Home/bin in the Oracle version.

You should also change the symbolic links in /System/Library/Frameworks/JavaVM.framework/Versions

Apple placed the JVM's in /System/Library/Java/JavaVirtualMachines while Oracle puts them in /Library/Java/JavaVirtualMachines

The Applet plugin is in /Library/Internet Plug-Ins
