Greetings!

 

I have a web app built with Maven I’ve added Logback to handle the logging with two rolling file appenders. Unfortunately, some exceptions (below) still bubble up to the server.log and are not captured in the logback generated files. How can I capture these with logback and keep them out of server.log?

 

15:46:41,888 SEVERE [javax.enterprise.resource.webcontainer.jsf.context] (http-) JSF1073: javax.faces.event.AbortProcessingException caught during processing of PROCESS_VALIDATIONS 3 : UIComponent-ClientId=templateForm:ddlCarrierView, Message=/foo/bar.xhtml @144,91 valueChangeListener="#{BackingBean.method}": java.lang.NullPointerException

…

Caused by: java.lang.NullPointerException

       at my.app.BackingBean.method(BackingBean.java:298) [classes:]

…

 

Below are the relevant configuration pieces.

 

Thank you for your help!
