You dont actually need to write your own Javascript to do this. Because you
are using the standard annotation based dispatching stuff you can just use
osapi. The default implementation of Shindig will introspect the API
endpoints to discover the set of available services and makes them available
to osapi.
Assuming that your class looks like
@Service("names", ...)
public classs MyNames {
...
@Operation(httpMethods = "GET")
public Future<?> processGetRequest(RequestItem request) throws
ProtocolException {
return processMessage(request);
}
...
}
Then if you require the "osapi" feature you will be able to call
osapi.names.processGetRequest({< params in JSON object
>}).execute(function(result){ /* callback */ });
to get a nicer method name in the JS just change the method name in Java or
use the aliasing feature of the Operation annotation.
