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

Question

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   Ans  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  export JAVA HOME   System Library Frameworks JavaVM framework Versions 1 6 0 Home    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

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

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

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

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
