Jboss Deployment Failure - ClassNotFoundException

Question

I encountered ClassNotFoundException during deploying a war file to my jboss server. I think it is related to log4j since it returns "Deployment error processing SCI for JAR: log4j-web-2.2.jar" error. However, the web app works properly on apache tomcat on eclipse. I have no idea of how to solve it. Thank you in advance.

Is there more to the stack trace? My guess is you're missing some log4j2 libraries. — James R. Perkins

@Code Eater encountered the same error on wildfly 8.2 for log4j-web 2.11 — Gaurav

From the log it looks like jboss needs a jar in your WAR's WEB-INF/lib - this is what it mean when it says java.lang.ClassNotFoundException: # from [Module "deployment.WarTest.war:main" from Service Module Loader]

There is a detailed discussion here: https://issues.apache.org/jira/browse/LOG4J2-890

although it looks like this error is "ClassNotFoundException", it is due to the a comment in the ServletContainerInitializer in meta-inf/services directory of log4j-web jar

If you're using Jakarta EE 9 or 10, you'll have to upgrade your version of Wildfly to a version that supports Jakarta EE > 9. In my case, I had the stable release of version 26 that supported Jakarta EE 8, and not 9. So I upgraded to the beta version (version 27) of Wildfly that came with support for Jakarta EE >= 9 out of the box. If you can't find the war file, generate it using the maven command mvn -e -U clean install
