Whichresource's classpath attribute is a
path-like structure and can also be
set via a nested <classpath> element.
The following shows using a classpath reference.
<path id="bsf.classpath">
<fileset dir="${user.home}/lang/bsf" includes="*.jar"/>
</path>
<whichresource property="bsf.class.location"
class="org.apache.bsf.BSFManager"
classpathref="bsf.classpath"/>
<echo>${bsf.class.location}</echo>
The following shows using a nested classpath.
<whichresource
property="ant-contrib.antlib.location"
resource="net/sf/antcontrib/antlib.xml">
<classpath>
<path path="f:/testing/ant-contrib/target/ant-contrib.jar"/>
</classpath>
</whichresource>
<echo>${ant-contrib.antlib.location}</echo>
