我想在gwt 2.6.1项目中添加一些websocket功能。 我遵循了所有指示。不幸的是我收到了一个错误：

   [WARN] FAILED AtmosphereServlet: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)Ljavax/servlet/ServletRegistration;
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)Ljavax/servlet/ServletRegistration;

堆栈跟踪：

它使用gwt eclipse插件部署在Jetty服务器上。

答案 0 :(得分：1)

看起来你正试图在Jetty 7上营造气氛。

{
    "error" : {
        "SaveContactMethod":"FirstName Invalid",
        "SaveContactMethod":"LastName Invalid",
        "SaveContactMethod":"MiddleName Invalid"
    }
}

在servlet api的第3版中添加。 Jetty 7实现了servlet api的2.5版本，因此没有实现getServeletRegistration方法。哪个应该解释异常。

您可以尝试将GWT Eclipse插件更新到3.0版。 （您可以在Eclipse市场找到它，并确保在安装新插件之前卸载旧插件。）

或者您可以尝试使用Tomcat 7或8等外部服务器。两者都支持Servlet 3.0 API。

希望有所帮助。
