I'm glad you found a solution!

Yes, you can do something similar to this snippet:
DirectionQueryOptions dirOptions = new DirectionQueryOptions();
dirOptions.setRetrievePolyline(true);
dirOptions.setRetrieveSteps(true);
Directions.load(
"from:here, usa to:there, india",
dirOptions, new DirectionsCallback() {
public void onFailure(int statusCode) {
Window.alert("Query failed: " + statusCode + " "
+ StatusCodes.getName(statusCode));
}
public void onSuccess(DirectionResults result) {
map.addOverlay(result.getPolyline());
}
});
}
Then, you can also retrieve the 2 endpoints from the DirectionsResult object
and create markers for them.
