How to get subproject file name from within the subproject?

["Hill, Richard" <ri...@attws.com>]

ANT: 1.5.4
JDK: 1.4.2_05
 
I have a project that calls a subproject. For example:
 
<project name="TestProject" default="test">
    <target name="test">
      <ant antfile="TestFile.xml"/>
    </target>
</project>
 
I would like to get the name of the subproject file (i.e. TestFile.xml)
from a target within the subproject itself. I've accomplished this
before using the optional 'script' task using something like: 
 
<target name="setupDirectories"> 
  <script language="javascript">
      <![CDATA[
          importClass(java.io.File);
          file = new java.io.File(
MyTestFileProjectName.getProperty("ant.file") );
 
...but I am have heck of a time with the subproject finding the bsf.jar
and js.jar due to resource conflicts. 
 
Is there another, easier way to get the subproject file name from within
the subproject itself. 
 
Thanks,
