org.vfny.geoserver.servlets.AbstractService

Represents a service that all others extend from. Subclasses should provide response and exception handlers as appropriate.

It is really important to adhere to the following workflow:

get a Request reader
ask the Request Reader for the Request object
Provide the resulting Request with the ServletRequest that generated it
get the appropiate ResponseHandler
ask it to execute the Request
set the response content type
write to the http response's output stream
pending - call Response cleanup

If anything goes wrong a ServiceException can be thrown and will be written to the output stream instead.

This is because we have to be sure that no exception have been produced before setting the response's content type, so we can set the exception specific content type; and that Response.getContentType is called AFTER Response.execute, since the MIME type can depend on any request parameter or another kind of desission making during the execute process. (i.e. FORMAT in WMS GetMap)

TODO: We need to call Response.abort() if anything goes wrong to allow the Response a chance to cleanup after itself.
