How do I override a JBoss module with my own from my WAR file?

I'm using JBoss 7.1.1 and trying to deploy a WAR file using Apache Commons Lang 3.3. The JAR is located in my WEB-INF/lib folder in my WAR file. However, when I run my web application, I get the below error/exception and I think that's because JBoss is using its own older commons-lang library . How do you override the JBoss commons lang module without modifying the JBoss installation?

To me it looks as if your code (or at least the code in org.mainco.subco.dido.service.TrainingSessionServiceImpl) still uses an older version of commons-lang. If you check out the Javadoc for commons-lang 3 you'll see that the code is under org.apache.commons.lang3 instead of org.apache.commons.lang3.
