问题
I am having issues with my Java path.
I have installed the latest version of Java 1.7.0_51. When I open the Java control panel it tells me "Your system has the recommended version of Java."
However when I go to terminal and type java -version I get
java version "1.6.0_32"
So after searching around I came across this SO Question which tells me that my Java home environment variable needs to be set.
I then opened the bash_profile file and added the below line to the top of the file, above my Python path info.
export JAVA_HOME=`/usr/libexec/java_home -v 1.7.0_51`
# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH
NOTE: I have tried this with both -v 1.7.0_51 and -v 1.7
I save the file and recheck in terminal but it is still showing
java version "1.6.0_32"
when I restart Terminal I do however see
Last login: Wed Feb 19 23:32:19 on ttys000
Unable to find any JVMs matching version "1.7".
localhost:/ user$
Note: Unable to find any JVMs matching version "1.7".
So it is trying to look for my 1.7, but just not finding it.
What am I doing wrong?
回答1:
Check whether there is an old version existed in the path
echo $PATH
Then set the java 1.7 bin directory.
export PATH=/usr/libexec/java_1.7_home/bin:$PATH
Then try to type in "java -version" in terminal to check the version

Ok, I think this must be specific to me. As above the Java control panel was saying that java 7 was installed. Also when i tried
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
I would get
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
But no mater what way I installed the JDK it would not work. It just didn't seem to appear anywhere on my machine. I still don't know why, but uninstalling (by simply deleting the 1.6 folder) the existing Java 6 from my machine and once again installing Java 7 JDK eventually fixed it.
Please give the up-votes to @diaz994 above.
