Hey all,
Well, I did some testing, and I tried to run this simples Java code:
public static void main(String args[]){
String JAVA_HOME = System.getProperty("java.home");
System.out.println(JAVA_HOME);
}
And it prints out: /opt/jdk1.6.0_06/jre
So, as Ashley said before, it is not an Ant's problem, it is an environment
or Java problem.
But, I checked, both, bash_profile and bashrc, and they all point to
/opt/jdk1.6.0_06, no JRE at all. So I was wondering where else could I look
at so I can find where this JRE is set.
Does anyone know where the method System.getProperty goes to get the
java.home? Like a file or something like that??
Cheers
PS: I also used that code to call and in my java code.
