Question

我们有一个GWT控制器。

@RemoteServiceRelativePath("xcontroller")
public interface MobileController extends RemoteService {
    WaterUtilityUserDataset getWaterUtilityUserDataset(String p_SearchText,
        int p_PageSize, int p_CurrentPage);
}

接口MobileControllerAsync重新声明MobileController中的方法。

public interface MobileControllerAsync {
    void getWaterUtilityUserDataset(String p_SearchText, int p_PageSize,
        int p_CurrentPage, AsyncCallback<WaterUtilityUserDataset> callback);
}

MobileControllerImpl实施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);
    }
}

存在MobileControllerMgr以将异步调用转换为同步调用。

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);
    }

客户端代码调用MobileControllerMgr。

的此方法

    MobileControllerMgr.getWaterUtilityUserDataset(
            l_searchText,
            m_ResultSize,
            1,
            getcallbackWaterUtilityUserList(p_uiList, p_uiListScroll,
                    p_uiPaginate, p_uiWait)
    );

回调报告错误。从日志中检索以下内容：

这里可能有什么问题？

Answer 1

您看到的例外解释了错误：

此应用程序已过期，请单击“刷新”按钮你的浏览器。

当您的浏览器中的代码来自与服务器上的代码不同的版本时，会发生这种情况。

处理此调用时抛出了IncompatibleRemoteServiceException。 GWT
