you pass it like any other argument to the java task via nested arg values or arg line
Note that vmargs like f.e. -Dwhatever=foobar are passed as jvmarg to the java task

f.e. your propertyfile aa.properties looks like :

vmarg.foo=-Dsomevalue=whatever
arg.key=value
arg.foo=bar
...

ant then

<target name="tst">
 <property file="aa.properties"/>
 <property name="homepath" value="${home_path}/"/>
 <java classpathref="clspath" classname="com.mytest.myapp" fork="true">
  <jvmarg value="${vmarg.foo}"/>
  <arg value="${homepath}"/>
  <arg value="${arg.key}"/>
  <arg value="${arg.foo}"/>
  ...
 </java>
</target>
