Change java version (MAC)

There are 2 Java versions on my computer:

/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

1.6. 0 is set as the default How to make my java program run 1.7?

Attempt to add:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home

It's mine Zshrc file But this only seems to change the path of Java commands on my terminal

Also try changing the home symbolic link as follows:

cd /Library/Java
mv Home Home-1.6
ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home/ Home

This has no effect at all

I have also tried Java conversion software: http://www.guigarage.com/2013/02/change-java-version-on-mac-os/ But it didn't work

Know how to launch version 1.7 by clicking on them App and Java programs such as jar files?

Solution

I believe OS X (at least 10.8) uses the following path:

> JRE：/System/Library/Frameworks/JavaVM. framework/Versions/Current > JDK：/System/Library/Frameworks/JavaVM. framework/Versions/CurrentJDK

These are symbolic links that you can update to point to the 1.7 installation

You can verify this quite easily:

a) Run which java to check which Java executable is executing In theory, that should be / usr / bin / Java

b) Run LS - La on the Java executable, which should tell you the location it points to (/ system / library / frameworks / JavaVM. Framework / versions / current / commands / Java on my machine)

I think this should sort you out Jar execution problem If your Java application is wrapped in In app, I think it's a little complicated: if memory service is used, the Java version used will depend on Javaapplicationstab. Used by app
