我正在启动一个基于Java和tomcat的应用程序。我收到以下错误。

I am starting a java and tomcat based application. I am getting the following error.

我已经检查了所有配置文件。

I have checked all the configuration file. Any lead is appreciated.

推荐答案

看来，这是由在命令中使用 java代理引起的。运行catalina -javaagent = ... 很奇怪。给我们

Got this, appears it was caused by the use of a "java agent" in the command that runs catalina -javaagent=... weird. Gave us

Caused by: java.lang.ClassNotFoundException: org/apache/xerces/jaxp/DocumentBuilderFactoryImpl

有时也给我们这样：

修复：暂时删除java代理参数，然后启动良好。
可能的解决方案：使其能够登录到其日志文件（权限）吗？

Fix: temporarily remove java agent parameter, then started up well. Possible fix: make it so it can log to its log file (permissions)?
