Log EL/JSP exceptions in tomcat

Question

I want to log the exception caused by EL (parsing/coercing to different type/NPE) or such other errors in JSP files into my tomcat logs.

Those are not logged automatically. What do I need to log those exceptions?

Answer 1

I also struggled with this a long time. But I finally found out, that the jsp-errors are logged in the localhost.<date>.log file.

Tomcat creates several log files (maybe depending on your local configuration):

• catalina.<date>.log
• host-manager.<date>.log
• localhost.<date>.log
• localhost_access_log.<date>.log
• manager.<date>.log
