Question

我正在Glassfish 4服务器上使用Java EE 6和Primefaces进行Web应用程序。我越来越经常得到同样恼人的错误。我曾试图谷歌这个问题，但我还没有找到一个有效的解决方案。有时应用程序将完全没有问题地执行，但突然发生同样的错误一遍又一遍。这是我的Stack跟踪：

同样的错误会多次发生，但随后无法提供如下资源：jquery / jquery-plugins.js，layout / layout.js，jquery / jquery.js，primefaces.js。全部来自Primefaces图书馆。

这个错误已经困扰了我很长一段时间，并且非常感谢答案！

Answer 1

这很可能是一个灰熊框架的错误。

可能导致错误： https://java.net/jira/browse/GLASSFISH-20681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

在那个Jira中，有一个jar补丁。复制到modules目录，清除OSGI缓存（删除glassfish4 \ glassfish \ domains \ domain1 \ osgi-cache）并重新启动。这对我有用。

另见：GF4 incorrect timeout exception thrown in Servlet when multiple large responses are returned (requested)

Answer 2

请注意，客户端从HTTP服务器获取资源作为HTTP GET请求。这意味着对于每个CSS，JS或HTML文件，您都会收到HTTP请求。

打开浏览器Web控制台并单击网络。然后去任何网站，你会看到你收到了多少请求。

以下是有关您的问题的一些建议。

尝试增加服务器的最大池大小。在这里阅读http://docs.oracle.com/cd/E26576_01/doc.312/e24936/tuning-glassfish.htm#abeea - ＆gt;调整EJB池设置
尝试分析您的网络应用，看看对同一资源的请求是否过多。您可以在浏览器中执行此操作，如上所述。
分析您的JSP以获取无用的导入，包含或iFrames

我希望这会有所帮助
