[appengine-java] RemoteApi : Null pointer Exception

[pavb]

Hi

I have a nullPointerException when I try to insert data in my
production site.
It works with the local server. I have tried with the sample code of
the documentation but the error is the same.
I am using the version 1.5.0.1 of the java sdk

Sample code
public class RemoteApiExample {
    public static void main(String[] args) throws IOException {
        String username = System.console().readLine("username: ");
        String password =
            new String(System.console().readPassword("password: "));
        RemoteApiOptions options = new RemoteApiOptions()
            .server("<your app>.appspot.com", 443)
            .credentials(username, password);
        RemoteApiInstaller installer = new RemoteApiInstaller();
        installer.install(options);
        try {
            DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
            System.out.println("Key of new entity is " +
                ds.put(new Entity("Hello Remote API!")));
        } finally {
            installer.uninstall();
        }
    }
}


Exception in thread "main" java.lang.NullPointerException
