What you do normally in ant linguo is :

<fileset id="cxf-patches.fs" dir="${lib}">
<include name="cxf-xjc-boolean-2.3.0.jar"/>
<include name="cxf-xjc-bug671-2.3.0.jar"/>
<include name="cxf-xjc-dv-2.3.0.jar"/>
<include name="cxf-xjc-ts-2.3.0.jar"/>

you can then reference this construct like that

<path id="cxf-patches.cp">
<fileset refid="cxf-patches.fs"/>

A path can be used by any ant task which accepts paths, like <javac/>. 
The <pathconvert/> task can convert the path to a property using any 
separator you like.
