Answer 1

This problem happens when you try to deploy an ear/war/jar deployment in jboss7/wildfly and you have not specified what dependencies need your application.
Jboss7/Wildfly has his own module class loader to isolate applications and dependencies running into the same java virtual machine.
All deployments in jboss/wildfly are loaded as modules (not only the content included in modules folder, the content of deployments folder are modules too).
If you don't have packaged "struts" jar into the application deployment file, you will need to deploy the required dependencies as modules and tell to jboss that your application depends on it.
So, you have at least five alternatives:
Build your application as an Uber-Jar including your dependencies
inside.
Deploy your application and dependencies in the deployments folder and add a manifest entry in your application to tell to jboss that
your application depends on it.
Deploy your application and application dependencies (jars) in the deployments folder and add a jboss deployment descriptor xml in your
application to tell to jboss that your application depends on it.
Deploy your application in the deployments folder and create modules for your dependencies (if do not exist) and add a manifest
entry in your application to tell to jboss that your application
depends on it.
Deploy your application in deployments folder and create modules for your dependencies (if do not exist) and use a jboss deployment
descriptor xml in your application to tell to jboss that your
application depends on it.
