How to Set Java JDK Environment Variable for Mac OS X 10.8 Mountain Lion

Question

Can anybody tell me how to set environment variable for Mac OS X 10.8 Mountain Lion. I just upgrade my Mac to Mac OS X 10.8. When I run a script. It said that "/Users/ruijiaoli/lejos_nxj/bin/nxj: line 64: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java: No such file or directory" I found that JDK in the directory within the path above. And it worked well in Mac OS X lion. Is the JDK path changed in Mac OS X mountain Lion? The version of Java on my system is 1.6.

Accepted Answer

This is what I have tried:

create the bash_profile:

```
$ vim ~/.bash_profile 
```

add this to the file:

```
export JAVA_HOME=$(/usr/libexec/java_home)
```

execute the source command

```
$ source ~/.bash_profile
```

echo JAVA_HOME:

```
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
```
