来自域名但不是服务器名称的 HTTP 500 错误答案

【问题标题】：HTTP 500 error from domain name but not server name来自域名但不是服务器名称的 HTTP 500 错误
【发布时间】：2015-12-09 17:02:22
【问题描述】：

当我尝试访问 URL 时收到 HTTP 500 响应。但是当我用服务器名称替换域名时，它工作正常。什么可能导致问题？

 java.io.IOException: Server returned HTTP response code: 500 for URL: http://domainname/Test/test.jar

但是，我可以访问服务器上的其他资源，例如， http://domainname/Images/image.png

我不知道发生了什么。

跟踪 WAS 上的日志。

【问题讨论】：

当您看到此 500 错误时。您能否发布一些来自 $TOMCAT_HOME/log/catalina.out 的日志条目
这是在 WAS 上运行的
查看服务器日志以了解异常情况并在此处发布。
您使用的是哪个操作系统。您在使用 Tivoli Integrated Portal (TIP) 吗？
操作系统应该是 Windows 2008。我无法回答关于 TIP 的问题。我只是一个开发者。无法回答管理员和服务器相关问题。

【解决方案1】：

问题已解决：必须清除 WAS 服务器上的 Java 缓存。然后重新启动所有集群和节点就可以了。感谢您的帮助！！
