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,
