使用我的 gwt.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 1.6.2//EN" "http://google-web-toolkit.googlecode.com/svn/tags/1.6.2/distro-source/core/src/gwt-module.dtd">
<module rename-to='gwtmaps'>
  <!-- Inherit the core Web Toolkit stuff.                        -->
  <inherits name='com.google.gwt.user.User'/>

和 web.xml

  <!-- Servlets -->

有什么想法吗？我一直在尝试新的理论，但无法取得任何成功。

谢谢！

【参考方案1】：

您可能需要将@RemoteServiceRelativePath 注解添加到服务的客户端同步接口。

例如：

@RemoteServiceRelativePath("mapService")
public interface MapService extends RemoteService
