java - Why do you need synchronous interface for GWT RPC? -
i wondering why need define synchonous interface when using gwt rpc calls asynchornous (http://www.gwtproject.org/doc/latest/devguideservercommunication.html)?
i not see synchornous interface used!
i.e. why can't implement synchonous interface in our service implementation class?
from documentation:
http://www.gwtproject.org/doc/latest/devguideservercommunication.html#devguidecreatingservices
this synchronous interface definitive version of service's specification. implementation of service on server-side must extend remoteserviceservlet , implement service interface.
package com.example.foo.server; import com.google.gwt.user.server.rpc.remoteserviceservlet; import com.example.client.myservice; public class myserviceimpl extends remoteserviceservlet implements myservice { public string mymethod(string s) { // interesting 's' here on server. return s; } }
tip: not possible call version of rpc directly client. must create asynchronous
