Wrong, property values expand other property values (if the props are defined).

You type env. MYPROJECT
should be env.MYPROJECT
without space between env. and MYPROJECT

better
<path id="myclasspath">
<pathelement location=".">
<pathelement location="${env.MYPROJECT}/endorsed/xercesImpl.jar"/>
<pathelement location="{env.MYPROJECT}/endorsed/jdom.jar"/>
</path>
