How to create a setter for a GeoPt field of a JDO entity in App Engine datastore such that it shows up in the endpoint client library?

问题

I have a GeoPt field for a JDO entity on App Engine and I created the following setter for it:

public void setLocation(Float latitude,Float longitude){
    location=new GeoPt(latitude, longitude);
}

However, when I generate the Cloud Endpoints client library through Google Plugin for Eclipse, this method does not show up in the list of methods available for this entity.

How should I modify the setter such that the client library creates an endpoint for it?
