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

I have checked all the configuration file. Any lead is appreciated.
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
Also sometimes gave us this:

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