添加气氛后无法运行项目：（AtmosphereFrameworkInitializer.java:52）

我想在gwt 2.6.1项目中添加一些websocket功能。我遵循所有说明。可惜的是，我得到一个错误：添加气氛后无法运行项目：（AtmosphereFrameworkInitializer.java:52）

它被部署使用GWT eclipse插件Jetty服务器上。

它看起来像你试图在码头7

javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)

经营的氛围中的Servlet API 3.0版本中加入。 Jetty 7实现了servlet api的版本2.5，因此没有实现getServeletRegistration方法。这应该解释这个例外。

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外部服务器（如Tomcat 7或8）。两者都支持Servlet 3.0 API。

希望有所帮助。

我有我的项目和您的示例项目从相同的Eclipse /插件/码头运行。我的项目不起作用，你的工作。这怎么可能？我如何检查码头的版本？ – masterdany88

将logLevel设置为TRACE。在这种情况下，jetty的版本将显示在日志中。 –
