I am having a pathetic issue with Java in my mac osx 10.7.3 . Previously I installed it and it was working fine. After some changes in the .bash_profile and .profile file in the course of time, I am having an error like
Unable to locate an executable at "/usr/bin/java/bin/java"
whenever I try to run "javac" or "java" in my terminal .
echo $PATH
gives an output like :
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/sabya/Documents/Play_Framework/play-2.0:/usr/X11/bin:/usr/local/git/bin:/usr/local/mysql/bin
My .bash_profile looks like :
alias start_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM start"
alias stop_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM stop"
export JAVA_HOME=/usr/bin/java
Output of which java
/usr/bin/java
Its bugging me for long days and uninstalling and installing java did not help my luck .
I am a newbie in Mac and need help to sort out this issue .
Googled and saw SOF before posting this question but did not find anything specific to my problem .
Thanks
Sabya
For those using newer versions of java: jhat
has been removed since Java 9. Source: https://www.infoq.com/news/2015/12/OpenJDK-9-removal-of-HPROF-jhat/
That same article recommends using Java VisualVM instead.
In MacOS Catalina, run
sudo nano ~/.bash_profile
In bash_profile, add:
export JAVA_HOME=$(/usr/libexec/java_home)
source ~/.bash_profile
Verify by running java --version
i have experienced the same problem, and after reading this post i have double checked the JAVA_HOME
definition in .bash_profile
. It is actually:
export JAVA_HOME=$(which java)
that, exactly as Anony-Mousse is explaining, is the executable. Changing it to:
export=/Library/Java/Home
fixes the problem, tho is still interesting to understand why it's valued in that way in the profile file.
I faced the same problem. Updating bash_profile with the following lines, solved the problem for me:
export JAVA_HOME='/usr/'
export PATH=${JAVA_HOME}/bin:$PATH
For me, the problem occurs when I've downloaded macOS Compressed Archive
which underlying directory contains
jdk-11.0.8.jdk
- Contents
- Home
- bin
- ...
- MacOS
- _CodeSignature
So, to solve the problem, JAVA_HOME should be pointed directly to /Path-to-JDK/Contents/Home.
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
Because:
$ find /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home -name java*
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javac
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javadoc
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javafxpackager
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javah
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javap
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/javapackager
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/javafx-src.zip
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/bin/java
JAVA_HOME
is not the name of the java executable. But of the directory, java was installed in. The executable should be $JAVA_HOME/bin/java
.
The which
command is not helpful for you there. It will not give you the java home, but most likely this is just a wrapper or symlink to java installed in a very different directory.
