Question about validating environment variables and assigning parameters

All,

I am trying to do this:

<property name="javaBase" value="${system.JAVA_HOME}"/>

<target name="barry" if="javaBase">

        <echo message="TEST: JAVA_HOME is ${javaBase}."/>

</target>

The problem is, there will always be a value for ${javaBase}. See the
following output...

barry:
     [echo] TEST: JAVA_HOME is ${system.JAVA_HOME}.

How can I do it properly? Please help.

Thanks

Barry
