Start WildFly in domain mode Create a new Datasource with JNDI "java:/inexistentDatasource" and some fake db properties so that no connection can be stablished. Assign and enable the attached applications to a stopped server group. "example" references the created datasource, so its persistence unit creation will fail. "example-pu" is an empty war that will deploy successfully. Start the target server group. It'll fail with errors, since it won't be able to deploy "example". No errors will be shown in the UI ( HAL-996 ). Now go to the Deployments page. Select the server group to see its deloyments. You'll see a "no running server" message and you won't be able to view the details, although both applications are accesible from http.
