Multiple versions of Java on OS X Mavericks
Of course after OS X Mountain Lion it was the time to update my java on OS X Mavericks.
Let’s see how to use multiple versions of java on OS X Mavericks.
I plan to use Java7 and Java 8 from Oracle and to have an easy way of changing the default version.
As you probably know there is a difference between JRE and JDK.If not a very nice response you can find here.
Regarding JRE we should keep in mind that
1) “Only one JRE can be installed at a time. The system will not install a JRE that has a lower version than the current version. If you wish to install a lower version of the JRE, first uninstall the current version.”
2)”Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To be able to do this, you need to install the JDK.”
I installed JdK 7 and Jdk 8
Right after I installed Jdk8 it seems that the simlinks were updated and java -version returned
as well java_home was set to Jdk 8
In my .profile i have as well defined
As well i found very practical this command which is used to choose the default java_home. (it seems it iterates all java installations and the latest version is tool)
Now in order to have latest Jdk7 installed on my computer as default java I had to change in my .profile file
After opening a new terminal
Still
That however is not affecting the default java version as described above.
In order to change that you might need to uninstall the Jdk that points to or to use some kind of hacked

Hello,
I am new to mac and recently received a MBP as a gift. My operating system is OS X 10.9.5 (Mavericks). I apologize if this has been answered numerous times in the forum but I have not been able to find a solution to my problem.
I am trying to install Java for one website that my firm uses for VPN Remote Desktop connections. My colleagues use both Mac's and PC's to connect without a problem through this website. Java is required to run the scripts for our RSA token keys, the script is Array Solutions.
I recently tried to connect and was prompted to download the latest version of Java. I believe is was version 8. I downloaded the file and installed without a hitch. I checked my security settings etc. to make sure all was in order.
When I visited the site, I was prompted to accept the user certificate and allowed the site access to Java. It started to work and then I received a pop up window indicating that I need to install the most current version of Java. The strange part is that I have it. Needless to say, I was not able to gain access because my Java isn't working.
Is there a solution to this? Will I need to bring my Mac to my neighborhood store and have one the Geniuses configure my system?
