1) if your example is the one from "using ant" then it's just a snippet and there isn't enough context to see what ${classpath} refers to. Basically, some variable defined elsewhere is the correct (but not very helpful) answer - but ${classpath} itself has no magic value.
2) <echo>${classpath}</echo> prints "${classpath}" if ${classpath} is undefined, but prints the value of ${classpath} if it is defined:
<project name="mytest" basedir="." default="demo">
<property name="definedvariable" value="foobar"/>
<target name="demo">
<echo>${definedvariable}</echo>
<echo>${undefinedvariable}</echo>
</target></project>
H:\>ant Buildfile: build.xml
demo:
[echo] foobar
[echo] ${undefinedvariable}BUILD SUCCESSFUL Total time: 0 seconds

I have problem understanding <classpath>
From the manual:
//// <classpath> <pathelement path="${classpath}"/> </classpath> ///
What is ${classpath} referring to? Also, how do I get to print variables or properties <echo>${classpath}/<echo> prints "${classpath}", how do I get the actual value?
TIA
