心跳，同时有一个持久的要求 [英] Heartbeat while having a long-lasting request

问题描述

如何使用SEAM 2.x实现JSF 1.2，RichFaces 3.x的心跳，这也适用于用户执行的持久请求？

How can I implement a heartbeat with JSF 1.2, RichFaces 3.x using SEAM 2.x which also works during a long-lasting request executed by an user?

目前，我们有一个心跳（以避免会话超时）使用< aj4：poll action =＃{bean.keepAlive}... /> 在服务器上的长期请求期间不起作用。使用自己的 eventsQueue =heartbeat允许在执行长期请求时发送所需的心跳但将我们引导到 org.jboss.seam.ConcurrentRequestTimeoutException 。

Currently, we've got a heartbeat (to avoid session timeout) using <aj4:poll action="#{bean.keepAlive}" ... /> which does not work during long-lasting requests on the server. Using an own eventsQueue="heartbeat" allows that the required heartbeat is sent even while executing a long-term request but leads us into a org.jboss.seam.ConcurrentRequestTimeoutException.

我们也尝试使用 @Asynchronous on keepAlive 方法。

We also tried using @Asynchronouson the keepAlive method.

您是否有其他解决方案或提示我的问题？谢谢。 ：）

Do you have another solution or a hint to my problem? Thank you. :)

推荐答案

我们解决了运行心跳的问题在< iframe ...> 内。我实际上不是使用框架的朋友，但在这种情况下，它是一个干净，快速和肮脏的解决方案。

We have solved our problem running the heartbeat within a <iframe ...>. I'm actually not a friend of using frames but in this situation it's a clean quick and dirty solution.

我们仍在使用< a4j：在框架内轮询...> 。
