Instead of doing available on the individual jars, why not create your
classpath and then check if a specific class that would be in each jar is
available. For example

<project name="av" basedir="." default="test">
 <target name="init">
  <path id="clp">
   <pathelement location="c:\OpenSource\jdom\jdom\build\jdom.jar"/>
   <pathelement location="c:\tmp\foo.jar"/>

 <target name="test" depends="init">
  <condition property="avail">
	<available classname="org.jdom.Element" classpathref="clp"/>
	<available classname="org.jdom.Attribute" classpathref="clp"/>
  <echo message="Av = ${avail}"/>

Then you would only have the jars listed in one place, the classpath. Your
echos could be take care of in two statements. Put this

<propery name="clps" refid="clp"/> 

in your init. It just creates a property "alias" for the classpath you just
created and then put this

<echo message="CLPS = ${clps}"/>

wherever you want to echo the value. It will print out the classpath, which
is essentially what your echos were doing anyway.

Does that help?
