Help With Java

Open Terminal and type the following:

java -version

You should get an output similar to this:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)

If not, then you don't have any version of Java installed on your system. In this case, browse to any website containing a Java applet, e.g. http://www.jbox2d.org/v2demos/index.html, and Lion should prompt you whether you would like to download and install Java.

Hope this helps

 

What are you trying to run?
Some stuff requires a Java_home environment variable like the ones in Windows you know.

Just type in terminal
export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home"

That is if the program cannot find java because it doesn't check path.

Java is installed by default. Just tell us what you are trying to do that requires java and we can help.
