Jboss 8 WildFly: EAR Deployment ClassNotFoundException

Question

I have an EAR

EAR
 |-web (many wars)
 |-ejbs (many ejbs.jar)
 |-libs (one million lib jars)
 \-thirthapp
     |-web
     |  |-thirth.war
     |-ejb (some ejb.jar)
     \-libs (some specifics libs)

This work in JBoss 4.05 but not in WildFly 8 release. In WildFly all of Servlets in "thirth.war" throw an error:

Answer 1

Defining your package as a module on WildFly solves your problem. Package must contain com.wosocean.indexos.vc.servlet.IndexOsIntegracaoServlet class. If you do not have any idea about adding module into WildFly, you could examine JBoss Modules documentation.
