Java 如何在jsp中设置响应时间

我有一个关于如何设置服务器响应超时时间的问题

目前，我遇到了服务器无法在2分钟内响应的问题，并且当服务器在后台更新数据时，页面将不会得到更新

因为服务器端的性能现在无法提高，所以我想延长足够长的响应时间

还有一个问题我不明白。当响应超时时，请求将再次发送到服务器，我想知道谁对此负责

目前我正在使用Primefaces和Jboss。 下面是我得到的调用堆栈。该例程将每隔2分钟重复一次，使用不同的线程id：

没有服务器端重试机制设置。所以请帮我弄清楚

谢谢，

这个问题与我无关。。。还是我错过了什么？嗨，Kukeltje，我不确定它当前应该是什么问题，只知道因为服务器端性能很低，所以不会及时响应请求。再次发出了同样的请求。请帮助指出问题可能与什么有关，或者在哪里设置超时时间以使客户对请求更有耐心。我对web应用程序开发非常陌生。谢谢，请使您的代码异步，并使用轮询/推送检查代码是否完成。这在架构上和技术上都是一个更好的解决方案
