Subject Re: Java in JDK but ANT can't find it!
Date Fri, 15 May 2009 21:50:50 GMT
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.
