返回(请求)多个大响应时，在Servlet中抛出GF4错误的超时异常

本文介绍了返回(请求)多个大响应时，在Servlet中抛出GF4错误的超时异常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当GF处理多个请求(在此示例中，对于图像)时，会发生此问题.由于某些原因，响应outputstream阻塞(用于较大的写入)，几秒钟后我超时.

The issue occurs when multiple requests (in this example, for images) are handled by GF. For some reason, the response outputstream blocks (for larger writes) and I get a timeout after a few seconds.

我从 glassfish回购并替换了nucleus-grizzly-all.jar，但我仍然遇到相同的问题.

I downloaded the latest (2/12/2013) promoted built from glassfish repo and replaced nucleus-grizzly-all.jar but I still get the same issue.

关于导致此问题的原因以及如何解决此问题的任何想法?

Any ideas of what causes this issue and how I can resolve it?

谢谢.

推荐答案

更新GF4时，我做错了两件事.

I did two things wrong when updating my GF4.

  1. 我没有删除osgi缓存(... \ glassfish4 \ glassfish \ domains \ domain1 \ osgi-cache)
  2. 升级后的灰熊版本存在版本问题.

解决方案

在所附的Bug中(上方)，提供了一个jar补丁.我替换了jars到modules目录下，清除了OSGI缓存，现在一切正常.

In the attached Bug (above) there is a jar patch provides. I replaced the jar under modules directory, cleared the OSGI cache and everything works fine now.

这篇关于返回(请求)多个大响应时，在Servlet中抛出GF4错误的超时异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
