<h3>Parameters specified as nested elements</h3>
<h4>classpath</h4>
<p>
<code>Whichresource</code>'s <code>classpath</code> attribute is a
<a href="../using.html#path">path-like structure</a> and can also be
set via a nested <code>&lt;classpath&gt;</code> element.
</p>
<h3>Examples</h3>
<p>
The following shows using a classpath reference.
</p>
<blockquote><pre>
&lt;path id="bsf.classpath"&gt;
&lt;fileset dir="${user.home}/lang/bsf" includes="*.jar"/&gt;
&lt;/path&gt;
&lt;whichresource property="bsf.class.location"
class="org.apache.bsf.BSFManager"
classpathref="bsf.classpath"/&gt;
&lt;echo&gt;${bsf.class.location}&lt;/echo&gt;
</pre></blockquote>
<p>
The following shows using a nested classpath.
</p>
<blockquote><pre>
&lt;whichresource
property="ant-contrib.antlib.location"
resource="net/sf/antcontrib/antlib.xml"&gt;
&lt;classpath&gt;
&lt;path path="f:/testing/ant-contrib/target/ant-contrib.jar"/&gt;
&lt;/classpath&gt;
&lt;/whichresource&gt;
&lt;echo&gt;${ant-contrib.antlib.location}&lt;/echo&gt;
