[Apiman-user] How to set apiman logging (NullPointerException when using Log4j2LoggerFactory)

[ejlp ejlp]

Hi,

I was trying to use Log Header policy but no logging message shown in
Gatway's console or server.log.
I am using JBoss EAP 7.0 and Apiman 1.2.6.Final

This is what I've done in Gateway node:

* Use extracted war of apiman-gateway-api.war and apiman-gateway.war
* Put apiman-common-logging-log4j2-1.2.6.Final.jar into
<JBOSS_HOME>/standalone/deployment/apiman-gateway-api.war/WEB-INF/lib/
and <JBOSS_HOME>/standalone/deployment/apiman-gateway.war/WEB-INF/lib/
* Remove following line from apiman.properties

  apiman-gateway.logger-factory=io.apiman.common.logging.impl.NoOpLoggerFactory

  and put this line:

  apiman-gateway.logger-factory=io.apiman.common.logging.log4j2.Log4j2LoggerFactory

* Restart JBoss EAP

I got following stacktrace when EAP started:
