我們有一個GWT控制器。處理此調用時引發了IncompatibleRemoteServiceException。 GWT
@RemoteServiceRelativePath("xcontroller")
public interface MobileController extends RemoteService {
WaterUtilityUserDataset getWaterUtilityUserDataset(String p_SearchText,
int p_PageSize, int p_CurrentPage);
}
和接口MobileControllerAsync其中redeclares在MobileController的方法。
public interface MobileControllerAsync {
void getWaterUtilityUserDataset(String p_SearchText, int p_PageSize,
int p_CurrentPage, AsyncCallback<WaterUtilityUserDataset> callback);
}
MobileControllerImpl實現MobileController。
public class MobileControllerImpl extends RemoteServiceServlet implements
MobileController {
@Override
public WaterUtilityUserDataset getWaterUtilityUserDataset(String p_SearchText,
int p_PageSize, int p_CurrentPage) {
// TODO Auto-generated method stub
return AppSwitch.getWaterUtilityUserDataset(p_SearchText, p_PageSize,
p_CurrentPage);
}
}
A MobileControllerMgr存在將異步調用轉換爲同步調用。
public class MobileControllerMgr {
private static final MobileControllerAsync controller = GWT
.create(MobileController.class);
public static void getWaterUtilityUserDataset(String l_searchText,
int m_ResultSize, int currentpage,
AsyncCallback<WaterUtilityUserDataset> callback) {
controller.getWaterUtilityUserDataset(l_searchText, m_ResultSize,
currentpage, callback);
}
客戶端代碼調用此方法MobileControllerMgr。
MobileControllerMgr.getWaterUtilityUserDataset(
l_searchText,
m_ResultSize,
1,
getcallbackWaterUtilityUserList(p_uiList, p_uiListScroll,
p_uiPaginate, p_uiWait)
);
回調報告錯誤。以下是從日誌中檢索到的：
