Sorry that is invalid - invalid xml. Attribute values have to be quoted.
<echo message="${servrestart}"/>
Then the Ant runtime would search for a property servrestart and evaluates
that to its value or - if not set - to ${servrestart}. So you�ll get
a) with value=Hello World
[echo] Hello World
b) not set
[echo] ${servrestart}
Back to the original thread: what you can do with unset properties is
<target name="server.check">
<loadfile property="servrestart"> ...
</target>
<target name="server" depends="server.check" if="servrestart">
<echo>Property set. Server has to be restarted.</echo>
</target>
