wildcard multiple arg values to java task?

This is really just an ant question, but I can't find a way to do this one really useful thing. I'm betting someone else has seen the same need and hopefully solved the problem.

Here goes:
How do you wildcard arguments to the java task? I keep seeing things like this:

Code:

<java  classname="org.hibernate.auction.bench.client.BenchmarkSql" fork="true" dir="${classes.dir}">
            <classpath refid="lib.class.path"/>
            <classpath location="${classes.dir}"/>

            <arg value="${mapping.home}/foo.hbm.xml" />
            <arg value="${mapping.home}/bar.hbm.xml" />
        </java>

and what I really want to do is something like this:

Code:

<java  classname="org.hibernate.auction.bench.client.BenchmarkSql" fork="true" dir="${classes.dir}">
            <classpath refid="lib.class.path"/>
            <classpath location="${classes.dir}"/>

            <arg value="${mapping.home}/**/*.hbm.xml" />
        </java>

That way I could generate new mapping files and just let the ant task find and build based on them. I wouldn't have to shadow the new files in the ant task. The java task won't take filesets, and I can't get a refid in there either. Ant keeps failing at that point. Has anyone figured out how to do this?

Look at <Pathconvert> and use a space as the dir separator.

Thanks Max -- that was exactly the thing. For those that are interested, here is the solution:

set up these first:

Code:

<path id="mappingfiles.path">
      <!-- following pathelement didn't work, but fileset did
      <pathelement location="${mapping.home}/**/*.hbm.xml" />
      -->
      <fileset dir="${mapping.home}">
         <include name="**/*.hbm.xml" />
      </fileset>
   </path>

   <pathconvert pathsep=" " property="mappingfiles.list" refid="mappingfiles.path">
      <!-- 1.6.2 manual says a map is required, but this works
      <map from=" " to=" " />
      -->
   </pathconvert>

then use in schemaExport like this:

Code:

<target name="schemaExport">
      <java classname="net.sf.hibernate.tool.hbm2ddl.SchemaExport" fork="true">
         <!--
         <arg value="${mapping.home}/event.hbm.xml" />
         -->
         <arg value="mappingfiles.list" />
         <classpath refid="lib.class.path" />
      </java>
   </target>

That's it.
