There are at least two different ways on implementing the Map canvas with the Maps API for Java ME. One way would be to simply using the MapCanvas as directly a member variable as illustrated in helloMap.zip example, and other ways would include deriving new class from the MapCanvas and then using that new class JavaME_HelloMap2.zip when instantiating the Map. Basically both ways are working just as good, the selected way would depends on which way additional logic is going to be later on added to the application.
By default map is shown using English language texts in it, Setting the Map language in the Maps API for Java ME article shows how you could also utilize other languages.

The Map event handling with Maps API for Java ME is implemented very differently when compared to other Map APIs, basically there are only two real Map events generated, and they are implemented by MapListener interface. This interface defined two function mapContentUpdated() which is simply called for any change in Map, and mapUpdateError() which is called in case of error with maps updating. Additionally you can get pointer & key events by implementing a custom MapComponent and adding it to the Map, as explained in: Handling map events with Maps API for Java ME article.

The location of the user with Maps API for Java ME can be gotten by using PositioningManager. Using a JSR-179 Location Provider and displaying the result on a Map article shows on how this API can be used. Using the PositioningManager from Maps API for Java ME article extends this to also show the path moved in the map.
In case interaction is not really needed for the map application, or if you need to get static map image, then instead of using the Java ME Map API, you could utilize the Map Image API instead, ready made example for utilizing this API with Java is available at: Using the RESTful Map API with Java ME article.
