> I've noticed that names of additional config sources provided by EAP7-1386 are always:
> {noformat}
> null:null:ServletConfigSource
> null:null:FilterConfigSource
> null:ServletContextConfigSource
> {noformat}
> I've tried to enhance the https://www.geeksforgeeks.org/difference-between-servletconfig-and-servletcontext-in-java-servlet/ example with MP config, to get the different names
> Servlet additions:
> {code:java}
>         System.out.println("-------------------------------------");
>         System.out.println("Servlet context name: " + getServletContext().getServletContextName());
>         System.out.println("Servlet virtual server name: " + getServletContext().getVirtualServerName());
>         System.out.println("Servlet name from servlet config: " + getServletConfig().getServletName());
>         System.out.println("Servlet name: " + getServletName());
>         System.out.println("Servlet info: " + getServletInfo());
>         ConfigProvider.getConfig().getConfigSources().forEach(configSource -> {
>             System.out.println("=================================");
>             System.out.println(configSource.getName());
>             System.out.println(configSource.getOrdinal());
>             System.out.println("Property names: " + configSource.getPropertyNames().stream().collect(Collectors.joining(", ")));
>         });
>         System.out.println("-------------------------------------");

> My simple-minded expectation would be that the config sources will use the fields provided in the name.
> *Reproduce:*
>  * start standalone server
>  * deploy {{source-names.war}}
>  * curl http://localhost:8080/source-names/servlet1
>  * see server logs
