If I copy the attached sample struts 2 application to C:\jboss-5.1.0.GA\server\default\deploy and hit the following url http://localhost:8080/Struts2_Annotations_Mvn/ everything works fine.
If I deploy the application in exploded form (C:\jboss-5.1.0.GA\server\default\deploy\Struts2_Annotations_Mvn.war\WEB-INF, META-INF, index.jsp) and hit the url: http://localhost:8080/Struts2_Annotations_Mvn/ the main page will load but if I click on the "Get your hello." link it does not work and I receive the following error:

Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: struts.devMode=false in your WEB-INF/classes/struts.properties file.
What is different between the two deployment methods that would cause the difference in behavior?
