[undertow-dev] Undertow jboss logging redirect to logback log file and console

[Steve Hu]

Hi Bill,

My exception handler is the first in the chain and it captures majority of
exceptions but this one. It is basically a try/catch block to wrap all
handler calls and you can find the source code at
https://github.com/networknt/light-java/blob/master/exception/src/main/java/com/networknt/exception/ExceptionHandler.java

I will try to dispatch in this handler first tonight and see if it works
based on your recommendation.

Hi Miere/Kim,

I am in the office now and will try both your approaches tonight on my home
computer.

Thanks a lot for your help.

Steve
