Installed Java 7 on Mac OS X but Terminal is still using version 6

Oracle's installer puts java inside the /Library/Internet Plug-Ins/JavaAppletPlugin.plugin. And it doesn't overwrite /usr/bin/java. So, if you issue a

whereis java

in the terminal, it'll return /usr/bin/java. (which in turn points to /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java, which is Apple's 1.6 version).

So, if you want to use the new java version, replace the /usr/bin/java symlink so that it points to /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java instead:

sudo rm /usr/bin/java
sudo ln -s /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin

Install the JDK 7 and this problem will solve itself.

Be sure to get the Java Development Kit (JDK) which includes compilers and stuff like that, rather than just the Java Runtime Environment (JRE) .

---

vi ~/.bash_profile

add

export JAVA_HOME=`/usr/libexec/java_home -v 1.7`

This tells your /usr/bin/java link target to use the latest Java 7 Package installed in

/Library/Java/JavaVirtualMachines/

So for JDK 1.7.0_17 JAVA_HOME would be:

/Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home

Note: There were a lot of change in this area recently to move Mac OS X from Appels own System integrated Java packages to Oracle based Java Packages. The above solution is working fine as of Mac OS X 10.8.2

Because you need to enter in Java Preferences pane and flag only the JVM 7 in this way :

To easily and quickly open the Java Preferences pane in Mac OS X you can simply call spotlight with ⌘+SPACE and type System Preferences it will show up in the last row of the window.

In my case, the issue was that Oracle was installing it to a different location than I was used to.

Download from Oracle: http://java.com/en/download/mac_download.jsp?locale=en

Verify that it's installed properly by looking in System Prefs: Command-Space to open Spotlight, type 'System Preferences', hit enter. Click Java icon in bottom row. After the Java Control Panel opens, click 'Java' tab, 'View...', and verify that your install worked. You can see a 'Path' there also, which you can sub into the commands below in case they are different than mine. Verify that the version is as you expect (sub in your path as needed): /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version Create link from /usr/bin/java to your new install sudo ln -fs /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin/java Sanity check your version: java -version

I had run into a similar issue with terminal not updating the java version to match the version installed on the mac.

There was no issue with the JAVA_HOME environmental variable being set

I have come up with a temporary and somewhat painful but working solution.

In you .bash_profile add the line:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_11.jdk/Contents/Home"

(This is the path on my machine but may be different on yours, make sure to get yours. The paths should match up to /Library/Java/JavaVirtualMachines/)

the run source ~/.bash_profile

As I mentioned this is a temporary band-aid solution because the java home path is being hard-coded. There is really no way to set the path to get the latest as that is what Apple is supposedly doing for terminal already and the issue is that Apple's java_home environment variable is not getting updated.

---

Since El Capitan, it is difficult to delete the /usr/bin/java symlink, because of the introduction of the new "rootless" policy.

Therefore, I simply added the path to the latest java version (in my case this is /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin) to the PATH in my .bashrc file:

# Use latest java version
export PATH=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH

To reload your .bashrc file for the current session, run source ~/.bashrc in the shell. You only have to do this for sessions that had been started before changing the .bashrc file.

Now the latest version is used, when you use java in the shell.

Update

brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk/openjdk/adoptopenjdk8

https://stackoverflow.com/a/28635465

Old version For me the easiest and cleanest way to go is to install Java using homebrew like described here:

https://stackoverflow.com/a/28635465

brew update
brew cask install java

---

You can execute following command in your terminal :

export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH"

And this replaces the java old with new one.

The basic issue: /usr/bin/java is pointing to one provided by OSX itself initially (/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java) We need to point this to the one downloaded by the JDK installer. The below steps are for OSX 10.10.4 Yosemite.

Open System Preferences -> select Java. The Java window opens.

Click on Java tab at the top. Click on 'View' button.

The Java Runtime Environment Settings tab opens as below:

Double click on the Path item and copy the path (cmd+c). This is the latest one installed by the JDK installer/updater. In my case, the path was /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

Open terminal. In this step, we are going to point (symbolic link, ln -s command) the system java binary to the latest one, which we discovered in the previous step. Run the below command:

sudo ln -s /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin/java

Thats it. To verify, you can just run java -version on the terminal. It should output the latest version that you installed/updated to.

I did

export JAVA_HOME=`/usr/libexec/java_home`

and that fixed my Java 8 issue.

before:

java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

after:

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

---

http://www.java.com/en/download/faq/java_mac.xml is a nice place to understand, while Apple is stopping support to Java, why Java Preferences doesn't exist anymore and rely on System_Preferences => Java => Java if Java 7 from Oracle is installed.

---

May I suggest you to have a look at the tool Jenv

This will allow you to switch at any time between your installed JVMs.

Simply as:

jenv global oracle-1.7

then later for test purpose:

jenv global oracle-1.6

And you have much more commands available.

Hard-coding the JAVA_HOME path might not be the best idea. The /usr/libexec/java_home utility sill works for me on Mac OSX Lion 10.7.5 and JDK 1.7.0_13. According to its man page, it is meant to be used with Apple's old Java Preferences pane, but it appears to be working with the replacement provided by Oracle (Java Control Panel). For example running /usr/libexec/java_home -V lists all installed JDKs (both 1.6.* and 1.7.*) on my machine.

So, as discussed in other threads (e.g. What should I set JAVA_HOME to on OSX), I would still recommend adding the following line to your .bash_profile:

export JAVA_HOME=$(/usr/libexec/java_home)

---

This is nuts! How does Oracle provide an installer that doesn't install anything!?

Anyways for me it was:

sudo rm /usr/bin/java
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/jre/bin/java /usr/bin/java

where 1.8.0_31 is your installed java version...

---

In case if you have several Java versions on your machine and you want to choose it dynamically at runtime, i.e, in my case, I have two versions:

ls -la /Library/Java/JavaVirtualMachines
drwxr-xr-x  3 root  wheel    96B Nov 16  2014 jdk1.7.0_71.jdk/
drwxr-xr-x  3 root  wheel    96B Mar  1  2015 jdk1.8.0_31.jdk/

You can change them by modifying the /etc/profile content. Just add (or modify) the following two lines at the end of the file:

export JAVA_HOME=YOUR_JAVA_PATH/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

In my case, it should be like the following if I want to use:

Java 7:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

Java 8:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

After saving the file, please run source /etc/profile and it should work. Here are results when I use the first and second option accordingly:

Java 7:

java -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)

Java 8:

java -version 
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)

The process is similar if your java folder is located in different locations.

Simple Solution

export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH"

---

I think you can try to install jdk not jre. By installing jdk, the java in /usr/bin/java will be replaced, and all library will work fine.

---

If you have Homebrew installed, you can install java-switcher to change Java default version more quickly

brew tap andycillin/tap
brew install java-switcher

Then you can use just one command to switch your default Java version.

java-switcher 1.7

or

java-switcher 10

---

You can run this command to find the version of Java that's under /Library/Internet Plugins/:

defaults read /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Info.plist CFBundleVersion

---

It is happening because your .bash_profile is not reflecting changes.To reflect it, just use the following command

$ source .bash_profile

---

Since i have not faced this issue , I am taking a hunch --

Can you please try this :

Where does the soft link "java_home" point to :

ls -lrt /usr/libexec/java_home

Output : (Stunted) lrwxr-xr-x java_home -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home

**ls -lrt /System/Library/Frameworks/JavaVM.framework/Versions My MAC Produces the following :

 lrwxr-xr-x CurrentJDK ->
 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents**

 lrwxr-xr-x   Current -> A
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.6.0 -> CurrentJDK
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.6 -> CurrentJDK
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.5.0 -> CurrentJDK
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.5 -> CurrentJDK
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.4.2 -> CurrentJDK
 lrwxr-xr-x  1 root  wheel   10 Oct 18 14:39 1.4 -> CurrentJDK

Based on this , we might get a hint to proceed further ?

i resolved this issue by re installing Yosemite and then cross check java version on terminal (java -version) and (javac -version) .It work perfectly now.It is not changing to java 7 as version 6 still present on (command + n) libray>java>javavirtualmachine>your javac current version.you need to address to java home .

---

I resolved this issue with sudo rm /usr/bin/java

And I downloaded and installed the last Java SE Runtime Environment: http://www.oracle.com/technetwork/java/javase/downloads/index.html

sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/jre/bin/java /usr/bin/java did not work for me because I got Operation not permitted. El Capitan now protects certain system directories in "rootless" mode (a.k.a. System Integrity Protection). It is applicable to macOS Sierra, and probably new macOS versions for the foreseeable future.

---

Installing through distributed JDK DMG from the Oracle site auto-updates everything for me. I have seen (in El Capitan) updating through System Preferences > Java do updates but that do not reflect to command line. Installing through DMG does the job.

---

Check JDK versions installed:

$ ls  /Library/Java/JavaVirtualMachines/
jdk-11.0.2.jdk  jdk1.8.0_91.jdk

Now in your ~/.bashrc export JAVA_HOME specifying the version:

if [ -e /usr/libexec/java_home ]; then
  export JAVA_HOME=$(/usr/libexec/java_home -v 11)
fi

Source the bashrc file and the Java version will be updated:

$ java -version
java version "11.0.2" 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

---

The latest 100% effective method:

in bash:

vim ~/.bash_profile

add

export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH"

:wq to save

cmd+q force quit bash

open bash again, and type in java -version

But actually this path points to jre not jdk.

If you want to point the path to JDK, you need

Make sure you have installed JDK not a single JRE runtime replace previous path to PATH="/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk", you can go to /Library/Java/JavaVirtualMachines to make sure you have installed the version of JDK you expected.
