JBoss EAR deployment fails because WAR classes are unable to find jars from EAR/lib folder

I am using JBoss EAP 7 and want to deploy an EAR file in standalone mode (using standalone-ha.xml).

I went through almost everything available on StackOverflow/JBoss forums but couldn't make my deployment to work (correctly). I have followed the docs to the best of my abilities but still the deployment of EAR gives Exception on console because the jar files inside WAR/WEB-INF/lib are not able to see the jar files present int EAR/lib folder. I can't figure out what I am doing wrong.

Structure 
myEAR.ear
|- lib (contains a.jar)
|- META-INF
|--- maven (folder with pom)
|--- application.xml
|--- jboss-deployment-structure.xml
|--- MANIFEST.MF
|- myWar.war
|--- WEB-INF
|----- lib (contains b.jar)
|----- jboss-deployment-structure.xml (which should be ignored per the docs)
|----- (WEB-INF contains other files/folders such as classes,jsp etc
EAR- application.xml: 
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/application_7.xsd" version="7">
  <display-name>myear</display-name>
  <module>
    <web>
      <web-uri>myWAR.war</web-uri>
      <context-root>/mywar</context-root>
    </web>
  </module>
  <library-directory>lib</library-directory>
</application>
EAR- jboss-deployment-structure.xml: 
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <deployment>
    <dependencies>
      <module name="com.organization.global" export="true" />
    </dependencies>
  </deployment>
  <!-- Having/Not having below sub-deployment has no effect -->
  <sub-deployment name="myWAR.war">
    <dependencies/>
  </sub-deployment>
</jboss-deployment-structure>

Deployment succeeds if I copy a.jar inside WAR/WEB-INF/lib/ folder, otherwise gives an exception: Caused by: java.lang.NoClassDefFoundError related to a class specific to a.jar. I want my WAR to be able to get access to all the jars put together inside EAR/lib.

I read in one of the forums that the jar/classes in lib folder should be available to all modules within the EAR but sometimes they are not added automatically but I couldn't find the solution on how to add them.

Any guidance would be appreciated. Thanks in advance!

In JBoss EAP 7, to access lib files present in ear inside war you could try by adding a context param in your war's web.xml.

To create env variable try below in terminal:

export JAR_HOME=../jboss-eap-7.1/standalone/deployments/example.ear(Please add value equivalent to your environment and ear's path)
export PATH=$PATH:$JAR_HOME
Add this variable to web.xml as file:${JAR_HOME}/lib/example.jar

Read this context param inside your classes present inside war.
