I'd recommend writing an xml file like 

  <path id="${java-package-name}.classpath">
    <pathelement location="${output-jar}" />
    <pathelement path="${input1.classpath}" />
    ... 
    <pathelement path="${inputn.classpath}" /> 
  </path>

to a well-known location.  Then we could reuse those files in ant-
build-system.

Cheers
