Java Development Tools

First off, i've good experience in Java development. Anyway, i haven't started yet with Java ME. We want to develop a mobile version of our website. Unfortunatly, internet does not work very on a lot mobile devices. On the other hand a lot of phones support Java ME. Therefore, we are considering using Java ME for achiving our goal. But before starting i have some questions:

1) Our app will depend on Google Maps. Is it possible to use Google Maps directly from within a Java ME application, and can this map object be displayed in a panel in the programm?
2) How is data transfered between the mobile phone and Google Maps?
3) We have some business logic running on our server. The Java ME app only makes sense if we are able to get access to this business logic. Since the server is running a tomcat server it would be preferable to use http for this task. Is this possible?

Sorry this questions might seem stupid but until now i'm completly new to Java ME.
