list of files with ANT

Consider this scenario friends.

build.xml
|
|------------lib
|
|----------averyveryverylong.jar
|----------anotherlongjarfile.jar

now when I want to build a list of files in the lib folder I am using
<fileset dir="lib" id="hi">
<include file=".jar" /<
</fileset>

I then use pathconvert

<pathconvert pathsep="," property="testing" refid="hi" />

what I am getting is
c:\lib\averyveryverylong.jar,c:\lib\anotherlongjarfile.jar

but that is not what I am expecting.

I am expecting just averyveryverylong.jar, anotherlongjarfile.jar

Can you help me out as to how to get this ?
