Thanks,

 so given a build.xml ...

<project name="Test" default="test" basedir=".">
	<target name="test">
		<property name="param" value="123" />
		<namespace.MyTask/>
		<property name="ParamProp" refid="${param}.prop"/>
		<echo message="ParamProp = ${ParamProp}"/>
	</target>
</project>

And  the java code for the task ...

package namespace;

import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Task;

public class MyTask extends Task
{
	

	@Override
	public void execute() throws BuildException
	{
		getProject().addReference("123.prop", "franjipan");
	}
	
}

I get "franipan" echo'd...
