bashrc alias java_jre='/Library/Internet\ Plug-Ins/ugin/Contents/Home/bin/java' Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode) Java(TM) SE Runtime Environment (build 1.7.0_13-b20) $ /Library/Internet\ Plug-Ins/ugin/Contents/Home/bin/java -version This is a fixed path and you can only have one "public" JRE installed at any given time. If you want to run the 1.7 or 1.8 JRE from the command line, it can be found in /Library/Internet Plug-Ins/ugin/Contents/Home/bin/java.

This will pick up the latest installed JDK for the relevant major version, you don't need to remember to change the NN by hand when you install an update. The same applies to Java 8 (using -v '1.8*'). You can use the /usr/libexec/java_home tool to find the right value automatically, for example to make /usr/bin/java use Java 7 you can do export JAVA_HOME=`/usr/libexec/java_home -v '1.7*'`Īnd to make it use Java 6 you can do export JAVA_HOME=`/usr/libexec/java_home -v '1.6*'` You can switch back to 1.6 simply by pointing your JAVA_HOME to /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home instead. The JDK installs into /Library/Java/JavaVirtualMachines/jdk1.7.0_NN.jdk (for whatever value of NN), so set your JAVA_HOME environment variable to /Library/Java/JavaVirtualMachines/jdk1.7.0_NN.jdk/Contents/Home to make /usr/bin/java use 1.7. These stubs respect the setting of your JAVA_HOME environment variable, but for this to work you need to install the JDK (from ) as opposed to the JRE (from ).

On Mac OS, /usr/bin/java and friends are stubs that delegate to the real JDK commands.

How can I get the terminal to use the correct version of Java? From what I've seen in other articles, this is where the Java 1.7.0's version folder should be.
When I navigate to /Library/Java/JavaVirtualMachines/ I'm presented with an empty folder. jar file from the terminal results in runtime errors due to the older version. jar files correctly when double-clicking them, but the terminal window's version is still 1.6.0_43 and running the same.
The problem I'm running into is, when I install Java 7 from Oracle's website, it updates the preferences menu and appears to execute.

Check your version jenv versionsįor setting system wide java version jenv global 14.Ok, I'm a bit new to Macs and OSX, but I picked one up so that I can do some troubleshooting on my Java programs with one since the company I work for uses a combination of OSX and Windows machines.
