  • failed to start Context, TOMCAT 8
    via Stack Overflow by Ftapia23
    ,
  • My code compiles fine and my app deploys to Tomcat 8 but I'm getting the following error in my Tomcat localhost log when the app attempts to start. Any ideas on how to resolve this (or even how to get further debug info for where the issue is)? I have enabled FINE logging on the localhost log and found several other filters starting with no exceptions (see below updated log output). Why is the struts2 filter specifically having issues and all of these other filters aren't? Also as a test, I commented out the struts2 filter (org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter for me) and the application installs and starts with no issues. So, the problem is certainly localized to the struts2 filter. from my tomcat localhost log... {noformat} 13-Jul-2016 16:22:34.847 FINE [http-nio-8080-exec-1]
