Class ServiceEngineServletContextListener


public class ServiceEngineServletContextListener extends Object
This the glue that manages a ServiceEngine over the lifetime of a ServletContext. If we're running a Standalone webserver, one of these is created manually, with a ServiceEngine supplied a the constructor. It's presumed that ServiceEngine is already configured. And if this is running in a larger web server it's created by virtue of it being a @WebListener - no ServiceEngine is supplied. In this case it looks in WEB-INF/service-engine.json for the configuration file. In theory it could then listen for changes to the ServiceEngine and act on those, ie if the paths change. This is not yet implemented.
