iOS Question b4ibuildserver.jar installation issue

[shasunder]

I am trying to install b4ibuildserver.jar in my local Mac Machine. I confirmed that I am using the latest version of Java. But when i try to install using terminal, i receive the below message.

iPhones-Mac:macserver iPhone$ java -jar b4ibuildserver.jar

It seems like there is another version of Java installed on your Mac and is set as the default Java.

Please run java -version and see which java version is actually executed.

You was correct Erel

iPhones-Mac:macserver iPhone$ java -version
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

I manually uninstalled the existing JDK, again downloaded and installed the latest version of JDK and it helped. Please see below.

iPhones-Mac:macserver iPhone$ java -version
java version "1.7.0_72"
