因此，我已经完成了对Tomcat 7及其当前运行的7.0.100的更新。到目前为止，还不错，但是启动服务器后，我的web应用现在抛出了一个我从未见过的错误：

我似乎试图将配置文件作为类加载！？有人知道这是哪里来的吗？

更新tomcat 7后出现类似问题。最终发现文件/ etc / tomcat / server.xml已更新。现在，AJP连接器已被注释掉。
<!-- Define an AJP 1.3 Connector on port 8009 -->
<!--
<Connector protocol="AJP/1.3"
address="::1"
port="8009"
redirectPort="8443" />
-->
取消注释该行并重新启动tomcat之后，我们的应用程序再次开始工作。
