Netbeans Tomcat - Cannot access WADL. Please restart your REST application

Question

Im using netbeans and the application is deployed in tomcat localhost:8080.

But when I try to test the web services, I'm getting the following error message.

Webpage is opening in localhost:8080 as well. Please find the screenshot below.

Application Config file is updated as below,

public class ApplicationConfig extends ResourceConfig {

public ApplicationConfig() {

register(com.test.serverdetails.camrnvcenter.ServerInventoryRestful.class);
    register(com.dso.selfhealing.vmreset.VmController.class);
    register(com.dso.initiative.InitiativeController.class);
}
