Anyone know how to remove Java 7 from Mountain Lion?
Installed it, didn't work properly so installed Java 6 and now everything works fine. Want to now get rid of Java 7.
Done it, I kept searching for mountain lion, searched for remove java 7 from mac and it was the same as doing it on mountain lion anyway:
http://www.java.com/en/download/help/mac_uninstall_java.xml
that solved it.
have you looked at your Java Preferences? /Applications/Utilities I dont think it will allow you to remove Java 7 but it will enable you to decide which version to use by default. Also if you are using an IDE such as Eclipse you are able to set a preference for a particular version on different projects. Can you give more details about it not working properly?

So if I wrote an application for windows 8-10 on java, would it work for old versions like windows 98. And will it work correctly?
Both of them got the newest versions of JRE for example.
Well, you can't install Java 8 on systems older than Vista, so some programs might not run (specifically ones that use Java 8 features and APIs). Otherwise, they would work the same way, unless you do some sort of hacks that may break things.
If you had done your project in oldest version of java supported in vista/xp/windows 7 systems your application works perfectly it only depends on java environment once if it is satisfied your application will run without any compactability issues.

Hello everyone I'm looking for method to change my default java for macbook air. I'm new user in mac and I dont know how and where to do it. I've installed Java 7 from Oracle website but when I want to run eclipse it shows alert that I need java 7 version.
Make sure that you've set your JAVA_HOME environment variable: http://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/index.html
This means put the following in your ~/.environment file:
export JAVA_HOME=jdk-install-dir
export PATH=$JAVA_HOME/bin:$PATH`

I'm trying to upgrade to Java 7 on my 2010 macbook pro running OSX Lion. I downloaded jdk 7u15 and it goes through the entire install procedure flawlessly. However when I went to add it into Eclipse I found it was not under System/Library/Java/JavaVirtualMachines as was Java 6. I can't find it anywhere.
On Mountain Lion, mine is in /Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/
Use /usr/libexec/java_home -V on a Mac to see all JDK versions installed. (JDK 7 versions reside normally under /Library/Java/JavaVirtualMachines).

Is there a way to set Java 7 so it will update automatically? I using JDK Standard edition on windows 7, 64bit. Java 6 would check for updates automatically and prompt you to install them. However, Java 7 doesn't appear to have any update mechanism. Even the "Update" tab in the Java Control Panel is gone.
I think this might be the issue. From the Oracle Download Help pages:
Q: Why is the Update tab missing from the Java Control Panel?
A: Java Auto Update is currently not available for 64-bit versions of Java. 64-bit versions of Java do not include the Update tab in the Java Control Panel.
See also:
"Java control panel does not show update tab on windows-7-x64" on superuser.com.

we are trying to install a newer version of java but are not able to because there is a program that is using a previous version. we dont know what that program is. is there a way to get a list of prgrams that are currently using java?
If you're using windows, then download Process Explorer. This will give you access to all of the processes currently running, along with their children. It gives much more detailed information than Task Manager.
An easy way which would cover majority of cases is this:
1. search for all files with the extension JAR
2. search for all files called java.exe file - usually programs which require java have the jre installed in their directory structure
