Creating Your Data Service
In order to create your data service for your server, you need to define both a service
interface and the actual service. For your service interface you need to define the
interface extending the GWT RemoteService interface,GWT RemoteService
interface, as shown in Listing 7-7. Your service will consist of the following methods
that will be called from your client:
1.
getProjects
: Returns an
Array
of
Strings
for the Project picklist
getMilestones
: Accepts a project name and returns an
Array
of
Strings
for the Milestones picklist
2.
3.
addEntries
: Accepts a
Vector
of
TimeEntryData
objects and returns
a
String
with the results of the datastore commit
getEntries
: Returns a
Vector
of
TimeEntryData
objects containing
the current timecard entries for the current user

Listing 7-7. Your data service extending the GWT RemoteService
package com.appirio.timeentry.client;
import java.util.Vector;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.appirio.timeentry.client.TimeEntryData;
@RemoteServiceRelativePath("data")
public interface DataService extends RemoteService {
