I’ve installed JDK 7u7 downloaded from oracle’s website. But after installation, the terminal is still showing java version 6
$java -version java version "1.6.0_35" Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811) Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode)
any idea why java 7 is not showing up?
OK, the problem has been resolved. Here is the answer:
I found that my Terminal has a .bash_profile and the java home variable is set to 1.6
So this is the line causing the problem every time I opened a new terminal window.
Simply remove this line will solve the problem. You still need to follow what @aleroot said, but if that doesn’t work for you, check the .bash_profile (or .bashrc) setting file to see if you’ve previously exported any java version.
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.
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
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) .
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
So for JDK
JAVA_HOME would be:
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
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:
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:
(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/)
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
# 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
Now the latest version is used, when you use
java in the shell.
The basic issue:
/usr/bin/java is pointing to one provided by OSX itself initially (
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
Pathitem and copy the path (cmd+c). This is the latest one installed by the JDK installer/updater. In my case, the path was
- Open terminal. In this step, we are going to point (symbolic link,
ln -scommand) 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
on the terminal. It should output the latest version that you installed/updated to.
and that fixed my Java 8 issue.
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)
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)
For me the easiest and cleanest way to go is to install Java using homebrew like described here:
brew update brew cask install java
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.
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:
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…
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.
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.
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
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 ?
It is happening because your .bash_profile is not reflecting changes.To reflect it, just use the following command
$ source .bash_profile
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:
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.
export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH"
