David ,
are you using an IDE to run this simple code or are you using the
command line?
is the 'ant' command line tool is working properly in a terminal?

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.

However I still believe the problem is with your environment rather than
your code.
Try editing the ant batch file or shell script in order to print out
JAVA_HOME and PATH and
just at the point where it runs org.apache.tools.ant.launch.Launcher.
Then print out all environment variables at the top of your build.xml file.
And print out
java.home at the start of your java application.
If you are forking the compiler, could it not be inheriting the environment
correctly?

Ashley, can you post a snippet of how you set up the project you launch
programmatically from java?
What does your build file that you are running from java contain in it?

Check your PATH to make sure you are launching your application from
the jdk and not the jre.
I launch programatically and I don't get these errors with the same
version of ant so it does
sound as if the problem lies outside of ant.

This is what I'm trying to tell you! My JAVA_HOME it is set as
/opt/jdk1.6.0_06 I've triple checked it on my bash file! I also
check with
echo $JAVA_HOME and which java, they all tell the right path, but
not ANT!
This is why I don't understand where does ant get this /jre !!

In your description you say that JAVA_HOME=/opt/jdk1.6.0_06/jre
Seriously, try JAVA_HOME= /opt/jdk1.6.0_06 instead

When I had this problem, I KNOW that JAVA_HOME was set correctly. I
still ran into the problem. The OP here also said JAVA_HOME was set
correctly. There is some missing step here that prevents the ant
Project
instance from knowing which Java to use.

It looks like you are pointing to the jre not the jdk.
Try repointing the JAVA_HOME environment variable to the jdk
directory
instead,

Hello Everyone,
I am running ANT programmatically in JAVA. So, my task is to
build the
BUILD.XML.
I'm able to do so, but it throws an exception saying:
/scratch2/nemer/test/xfire/build.xml:5: The following error
occurred
while
executing this line:
/scratch2/nemer/test/xfire/build-common.xml:81: Unable to find a
javac
compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/opt/jdk1.6.0_06/jre"
But in the end it says: BUILD SUCCESSFUL (but it still throws that
exception).
I already set all of my environment variables to /opt/jdk1.6.0_06/
(JAVA_HOME and also in PATH), which is a JDK! And even on the error
message
it says that the java is set to /opt/jdk1.6.0_06/jre (which is a
JDK, I
don't know where it gets the jre from).
So, does any one know how can I solve this problem? Is there a
configuration
file in ANT that we need to set up! I'm stuck there!!
I'm running the ant 1.7.1.
Cheers,
