and a few explanation

Webcharge is my entry point for the project, as you can see in the stacktrace the exception is thrown (WebchargeService.java:21) where at that line i have private static WebchargeServiceAsync ourInstance = GWT.create(WebchargeService.class);

WebchargeService

@RemoteServiceRelativePath(value = "WebchargeService")
public interface WebchargeService extends RemoteService
{
String getMessage(MyUser user);
List<MyUser> getUserList();
List<MyUser> updateUser(MyUser user) throws Exception;
List<MyUser> selectByName(String name);
String getMessage(String msg);

public static class App
{
  private static WebchargeServiceAsync ourInstance = GWT.create(WebchargeService.class);

  public static synchronized WebchargeServiceAsync getInstance()
  {
    return ourInstance;
  }
}
}

and the code for WebchargeServiceAsync

public interface WebchargeServiceAsync
{
void getMessage(String msg, AsyncCallback<String> async);

void getMessage(MyUser user, AsyncCallback<String> async);

void getUserList(AsyncCallback<List<MyUser>> async);

void updateUser(MyUser user, AsyncCallback<List<MyUser>> async);

void selectByName(String name, AsyncCallback<List<MyUser>> async);
}

Any help is welcome :)

Thanks.

今天我遇到了完全相同的问题。这是解决方案：

文件：validation-api-1.0.0.GA-sources.jar 和validation-api-1.0.0.GA.jar 可以在可下载的gwt sdk 中找到，在编译或执行开发模式时应该在您的类路径中。源 jar 至关重要，因此彼得的解决方案不起作用。

GWT 2.3 需要 javax.validation jar：http ://mvnrepository.com/artifact/javax.validation/validation-api/1.0.0.GA

下载它并将其添加到您的项目 lib 文件夹中。

我有类似的问题，这是由错字引起的

错误（抛出演员异常）：

private final UserService userRpcService = GWT.create(UserService.class);

正确（添加...异步）：

private final UserServiceAsync userRpcService = GWT.create(UserService.class);

正如已经说明的例外：您是否忘记继承所需的模块？

例如，“我的用户”是否可用？

阅读此问题并查看答案后，解决方案如下：

如果您通过复制新的 gwt 文件来手动更新库：（我们很多人都这样做了）

  1. 将您的 validation-api-1.0.0.GA.jar 和 validation-api-1.0.0.GA-sources.jar 复制到 gwt-dependencies 目录中。

  2. 从类路径中删除所有 VAADIN_DOWNLOAD 变量。

  3. 使用以下条目将以下变量添加到项目的构建路径：gwt-dev.jar、gwt-user.jar、validation-api-1.0.0.GA.jar 和 validation-api-1.0.0.GA-sources。罐。

  4. 编译小部件集

  5. 享受生活

如果您没有通过复制新的 gwt 文件手动更新您的库：

  1. 更新你的插件
  2. 确保文件 validation-api-1.0.0.GA.jar 和 validation-api-1.0.0.GA-sources.jar 存在于 gwt-dependencies 目录中
  3. 修改现有变量并将 2 个新变量条目（validation-api-1.0.0.GA.jar 和 validation-api-1.0.0.GA-sources.jar）添加到您的类路径中。
  4. 编译小部件集
  5. 享受生活
