IBM Websphere v8.5.5.4：Websocket部署成功但客戶端未連接

Question

我能夠在我的Liberty概要文件中部署示例Websocket應用程序，並且它的測試工作正常。然後，我嘗試將相同的應用程序部署到實際的WAS v8.5.5.4（到目前爲止我知道WAS 8.5.5.4具有websocket支持）。看起來應用程序已成功部署並且可以訪問網頁，但WEBSOCKET功能不起作用，例如我的Web套接字客戶端無法連接到服務器。有些的SystemOut.log尾巴下面：

任何想法或建議？

目前，只有WebSphere Liberty配置文件支持websockets。完整（又名經典）WebSphere Application Server尚不支持websocket。檢查這page。

計劃對傳統WebSphere Application Server中的websockets和Java EE 7提供支持，但尚未提供。

如果您需要websockets功能，則必須使用Liberty Profile或Liberty Core版本。

順便說一句。 WebSphere Liberty完全支持生產使用。因此，如果您擁有傳統的WebSphere 8.5.5許可證，則可以使用Liberty進行生產。
