Take a look at the code for my XAPI servlet:
https://github.com/iandees/xapi-servlet/blob/master/src/main/java/com/yellowbkpk/geo/xapi/servlet/XapiServlet.java
There's a lot of HTTP and XAPI-related stuff in there, but the Osmosis
classes are there:
Line 130 and the "makeRequestIterator()" method create a data source
(querying the database)
Line 153 creates a data sink (a data output mechanism)
Line 162 and 164 process the data into the sink. (writes XML to the client)
