I have seen successful instance online to make Log4J2 works in JBoss EAP 6.x
My local war file has specific situation (JBoss EAP 6.4, JDK8):
The war is built on Spring 3 framework, where most logging is made by Apache Common Logging
Logging of the source code in the war is made by Slf4J
However, some in house dependencies in WEB-INF/lib is still made by Log4J 1.2, not slf4J
So I added following dependency to the project, listed below (only list the jar file instead of verbose pom xml):
### spring framework from jcl to slf4j
jcl-over-slf4j-1.7.25.jar
### slf4j to log4j 1.2 then to log4j2
slf4j-log4j12-1.7.25.jar
log4j-1.2-api-2.11.1.jar
### slf4j to log4j 2
slf4j-api-1.7.25.jar
slf4j-simple-1.7.25.jar
log4j-api-2.8.2.jar
log4j-core-2.8.2.jar
log4j-slf4j-impl-2.8.jar
My plan is to tell EAP 6.4 to never use any logging module from JBoss, instead just use whatever is provided from this war, so in the jboss-deployment-structure.xml I create following elements
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<deployment>
<exclude-subsystems>
<subsystem name="logging" />
</exclude-subsystems>
<dependencies>
<module name="oracle" />
</dependencies>
<exclusions>
<module name="org.apache.log4j" />
<module name="org.apache.commons.logging" />
<module name="org.jboss.logging" />
<module name="org.jboss.logging.jul-to-slf4j-stub" />
<module name="org.jboss.logmanager" />
<module name="org.jboss.logmanager.log4j" />
<module name="org.slf4j" />
<module name='org.slf4j.impl' />
<module name='org.slf4j.jcl-over-slf4j' />
</exclusions>
</deployment>
</jboss-deployment-structure>
And when the application starts, I can see following information show up in the server log, extracted here
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/jcl-over-slf4j-1.7.25.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/slf4j-log4j12-1.7.25.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/slf4j-api-1.7.25.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/slf4j-simple-1.7.25.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/log4j-1.2-api-2.11.1.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/log4j-api-2.8.2.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/log4j-core-2.8.2.jar" to module deployment.MyApp.war:main
Adding resource "/C:/Windows/content/MyApp.war/WEB-INF/lib/log4j-slf4j-impl-2.8.jar" to module deployment.MyApp.war:main
there is not much further information regarding logging in the server log, no error.
However no matter how I configure the log appender (ROL or Console), there is no log4J log generated. I use FileAppender but there is no log file generated.
I don't think it is caused by log4J configuration issue, because same war file with the same log4J2.xml the logging output fine in Tomcat 8
How can I make this right so at least the application output logging successfully.
There are multiple SLF4J bindings in your dependencies:
slf4j-simple-1.7.25.jar
slf4j-log4j12-1.7.25.jar
log4j-slf4j-impl-2.8.jar
Action 1: Remove slf4j-simple and choose one of slf4j-log4j12 or log4j-slf4j-impl.
Beside that, TWO API dependencies for log4j look suspicious:
log4j-1.2-api-2.11.1.jar
log4j-api-2.8.2.jar
Action 2: Remove log4j-1.2-api-2.11.1.jar since you use implementation version 2.8.2 of log4j.

The question is for the webapp WAR with Spring+Hibernate deployed to WF8.
After webapp upgrade from Hibernate-3.x to 4.x the Hibernate logging stopped working.
The Hibernate-3.x was using Slf4j. The Hibernate Log4j logging was configured in the webapp with declaration in jboss-deployment-structure.xml:
<exclusions>
<module name="org.apache.log4j"/>
<module name="org.slf4j"/>
<module name="org.slf4j.impl"/>
</exclusions>
This declaration makes all logging classes to be loaded from WAR, not WF8.
The Hibernate-4.x is using jboss-logging. The additional exclusion
<exclusions>
<module name="org.jboss.logging"/>
. . .
</exclusions>
initializes the webapp logger correctly but also breaks WF8 with Log4j error:
log4j:WARN No appenders could be found for logger (org.jboss.logging).
Questions:
• How to enforce loading classes from jboss-logging-3.x.Final.jar
in the webapp and ignore classes loaded from this jar in WF8?
• How to initialize jboss-logging in the webapp and not to break
the WF8?
See also https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly
Excluding JPA does not help:
<exclude-subsystems>
<subsystem name="jpa"/>
</exclude-subsystems>
I've written a small web app which disables Wildfly 10.1's slf4j implementation and uses its own logging libraries (logback). It works fine because LoggerFactory.getILoggerFactory() resolves to ch.qos.logback.classic.LoggerContext as result.
But then I use the same code for a larger application (with 52 jar files in WEB-INF/lib/) LoggerFactory.getILoggerFactory() still resolves to a JBoss implementation org.slf4j.impl.Slf4jLoggerFactory, as by default.
How can I investigate what exactly retains server's logging instead of the one of mine? (And fix the situation of course.)
Maven dependencies used: "slf4j-api" 1.6.1, "logback-classic" and "logback-core" 0.9.28.
File jboss-deployment-structure.xml, which is known to be located properly in both cases:
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
<deployment>
<exclusions>
<module name="org.apache.common.logging"/>
<module name="org.apache.log4j"/>
<module name="org.jboss.log4j"/>
<module name="org.jboss.log4j.logmanager"/>
<module name="org.jboss.logging"/>
<module name="org.slf4j"/>
<module name="org.slf4j.impl"/>
</exclusions>
</deployment>
</jboss-deployment-structure>
I know it's a old topic but i had a similar problem.
So, i will describe the problem and what i done to solve it.
I'm using spring-boot in my web application and running with jboss wildfly 10.
When i try to integrate sentry and logback on my project, the application reads the file logback.xml but use another logging system.
I realized that wildfly was ignoring logback and using jboss-logging instead.
So, i disabled the jboss logging module and than, my application started using logback and everything worked fine.
But this is how i disabled logging sub-system:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<deployment>
<exclude-subsystems>
<subsystem name="logging" />
</exclude-subsystems>
</deployment>
</jboss-deployment-structure>
The link when i found my anwser:
We have recently migrated from jboss 6.1 eap to 6.4 eap, but facing problem of class loading.
In my project lib We need to use apache httpcore 4.4.1, but apache httpcore 4.3.3 is included in 6.4. This previously wasn't a problem when we were using jboss 6.1 because the resteasy-jaxrs module.xml did not export httpcore library.
Now with jboss 6.4 we are getting exception :
Caused by: java.lang.NoSuchMethodError: org.apache.http.util.Asserts.check(ZLjava/lang/String;Ljava/lang/Object;)V
Its because runtime my project is using jar available from jboss and which does not having this method with required signature.
Now I want to force my application to not to use jboss jar and use jar available from web-inf/lib folder.
I have try to exclude this via jboss-deployment-structure.xml but somehow it is not working and still it is using jar from jboss only.
below is snap from the jboss-deployment-structure.xml file.
<deployment>
<exclusions>
<module name="org.apache.httpcomponents" />
</exclusions>
<dependencies>
module name="org.apache.httpcomponents" />
</dependencies>
</deployment>
Can someone please help me on this what is missing here or is there any alternative for this...
Since you are using JBoss EAP, you can apply the CP07 patch for EAP 6.4 (so your version would be JBoss EAP 6.4.7) where this issue has been addressed. I would highly recommend applying the CP07 patch.
Alternatively, you can set <module name="org.apache.httpcomponents" export="false"/> in the $JBOSS_MODULES\org\jboss\resteasy\resteasy-jaxrs\main\module.xml.
However, I would recommend applying the patch as the recommended solution. This way you will not modify the configuration that is shipped with the product.
To resolve the issue we can take one of the below approach.
Change $JBOSS_MODULES\org\jboss\resteasy\resteasy-jaxrs\main\module.xml
as suggested by CoolBeans.
You can use below option if you have no control(or not authorized) to update the Jboss server configuration.
Add below xml configuration in your jboss-deployment-structure.xml file
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclude-subsystems>
<subsystem name="resteasy"/>
<subsystem name="jaxrs"/>
</exclude-subsystems>
<!-- Exclusions allow you to prevent the server from automatically adding
some dependencies -->
<exclusions>
<module name="javax.ws.rs.api"/>
<module name="org.jboss.as.jaxrs"/>
<module name="org.jboss.resteasy.resteasy-atom-provider" />
<module name="org.jboss.resteasy.resteasy-cdi" />
<module name="org.jboss.resteasy.resteasy-jaxrs" />
<module name="org.jboss.resteasy.resteasy-jaxb-provider" />

This worked for me, Hope this will work for other
I'm running JBoss 6.1 EAP, one of the default modules has its own version of the org/omg/CORBA/ORB.class file, I want to use my own jar for that file. I've tried including it in my app's war file but it is still picking up the one from the JBoss module.
So the question is, what is the load order of modules in JBoss and how can I change it?
You need to include a jboss-deployment-structure.xml file with your artifact, and configure the file to exclude the container's CORBA impl.
Below is an example which will exclude log4j
<jboss-deployment-structure>
<deployment>
<!-- Exclusions allow you to prevent the server from automatically adding some dependencies -->
<exclusions>
<module name="org.apache.log4j" />
</exclusions>
</deployment>
</jboss-deployment-structure>
I'm developing some App and at some point I already had code using xmlsec 1.4.3 but JBoss 7 loads by default xmlsec 1.5.1 so my code blows up.
I've been reading through the documentation and ended here: https://docs.jboss.org/author/display/AS7/Developer+Guide#DeveloperGuide-JBossDeploymentStructureFile
So, theoretically if I put the jboss-deployment-structure.xml on my WEB-INF folder (It is reading the XML because I failed writing properly the xsd and JBOSS crashed, and now without the xsd it says nothing) with this content:
<jboss-deployment-structure>
<ear-subdeployments-isolated>true</ear-subdeployments-isolated>
<deployment>
<!-- Exclusions allow you to prevent the server from automatically adding some dependencies -->
<exclusions>
<module name="org.apache.santuario.xmlsec" />
</exclusions>
</deployment>
</jboss-deployment-structure>
Then I would be able to use my xmlsec 1.4.3 and the module of JBOSS would be disabled.
However this isn't working.
What I am missing here? This should work right?
