  2. Copy the missing library to the correct location (cp /tmp/customizeACM/aveksa.war/AmazonAWSEntitlementCollector1/lib/jackson-databind-2.6.6.jar  /tmp/customizeACM/aveksa.war/WEB-INF/LocalAgent/common/lib/)
  3. Redeploy the Aveksa EAR file (cd /home/oracle/deploy && ./customizeACM.sh -d).

Other Application Servers (WebSphere, WebLogic)

Unpack the Aveksa EAR file and copy aveksa.war/AmazonAWSEntitlementCollector1/lib/jackson-databind-2.6.6.jar to aveksa.war/WEB-INF/LocalAgent/common/lib. You will need to redeploy the modified EAR file and restart the application for the changes to take effect.
