Have a look at: https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly

Our deployment structure looks essentially like this:

my.ear
  + lib/ <-- dependencies for multi-submodule deployment
  + META-INF/ <-- application.xml defines submodule(s) e.g. web.war, 
              <-- also jboss-deployment-structure.xml to include/export wildfly core modules for your EAR
  + web.war <-- our core deployment

I think in your case, you could just deploy your JARs to EAR/lib and they should be found across all submodules. From the Wildfly docs "Sub deployments (wars and ejb-jars) always have a dependency on the parent module, which gives them access to classes in EAR/lib"
