Flash Remoting application structure
31
5.
Configure Flash Remoting (create a gateway and a reference to a remote service).
6.
Call service functions and pass parameters.
7.
Handle the results and error status information returned to Flash in result event-handler
routines.
The following ActionScript example connects to the
petmarket.api.catalogservice
service,
creates the
catalogService
Service object, and calls two service functions,
catalogService.
getCategories()
and
catalogService.getProducts()
. These functions have corresponding
result-handler callback methods,
gotCategories_Result()
and
gotProducts_Result()
to
show the results in the Flash application. They also has corresponding fault-handler callback
methods,
gotCategories_Fault()
and
got_Categories_Result()
, to handle any error
information if the service call fails.
