using the -D option with the java task

While using the java task. I would like to be able to pass some properties
values using the -D option. Here is an excerpt from my build.xml file.

<target name="datarow">
    <java classname="com.cedera.util.datatransfer.DataLoadReportRow">
    <jvmarg
value="-Ddatadirectory=${src.data},-Ddatasource=${connection},-Dlogdirectory
=${src.log}"/>
    </java>
  </target>

The problem is that when I execute this I get null values for all these
properties.
Any ideas on how I can correctly use the -D option.

Thanks,
Atul

Atul,

They should be "pumped" back into Ant and displayed as your task executes.
Is the java command you are executing interactive (i.e. is it expecting
input)?

I tried fork. Now I cant see any of my system.out.println messages.
Why is that? Where are these redirected?

Did you get this message in your output?

JVM args ignored when same JVM is used.

Try adding fork="yes" which will create a new VM to which the args can
apply.
