Java GWT警告：找不到：/com.mycompany.project.ImageViewer/GreetingService的文件

不要连接到服务器。。。这是上一次gwt eclipse中的一个项目

在gwt中单击按钮：

greetServer(textToServer,
                        new AsyncCallback<String>() {
                            public void onFailure(Throwable caught) {
                                // Show the RPC error message to the user
                                dialogBox
                                        .setText("Remote Procedure Call - Failure");
                                serverResponseLabel
                                        .addStyleName("serverResponseLabelError");
                                serverResponseLabel.setHTML(SERVER_ERROR);
                                dialogBox.center();
                                closeButton.setFocus(true);
                            }

                            public void onSuccess(String result) {
                                dialogBox.setText("Remote Procedure Call");
                                serverResponseLabel
                                        .removeStyleName("serverResponseLabelError");
                                serverResponseLabel.setHTML(result);
                                dialogBox.center();
                                closeButton.setFocus(true);
                            }
                        });

gwt SERVISEASSYN文件：

public interface GreetingServiceAsync {
    void greetServer(String input, AsyncCallback<String> callback)
            throws IllegalArgumentException;
}


web xml

  <!-- Servlets -->
  <servlet>
    <servlet-name>greetServlet</servlet-name>
    <servlet-class>kill.server.GreetingServiceImpl</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/hello123/greet</url-pattern>
  </servlet-mapping>

  <!-- Default page to serve -->
  <welcome-file-list>
    <welcome-file>Hello123.html</welcome-file>
  </welcome-file-list>

---

怎么办？

在

web.xml

文件中，将服务映射为

/hello123/greet

：

<servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/hello123/greet</url-pattern>
</servlet-mapping>

public interface GreetingServiceAsync {
    void greetServer(String input, AsyncCallback<String> callback)
            throws IllegalArgumentException;
}


web xml

  <!-- Servlets -->
  <servlet>
    <servlet-name>greetServlet</servlet-name>
    <servlet-class>kill.server.GreetingServiceImpl</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/hello123/greet</url-pattern>
  </servlet-mapping>

  <!-- Default page to serve -->
  <welcome-file-list>
    <welcome-file>Hello123.html</welcome-file>
  </welcome-file-list>
