Glassfish. La ressource demandée() n'est pas disponible

Question

J'ai une installation de glassfish v3. J'utilise Maven pour déployer mon application.

Mais lorsque je tente de lancer l'application du navigateur revient avec:

La ressource demandée() ne sont pas disponibles.

Des idées?

Answer 1

When you launch an application from the admin console, you will access 
it at its document root. In your example, the launch link would look 
as follows: 

localhost:8080/HelloWorldServlet/ 

When you access an application at its document root, the container 
will check the application's document root folder for any welcome pages. 

You can define your own welcome page(s) in your application, but 
unless you do so, your application will inherit a predefined list of welcome 
pages from your domain's default-web.xml descriptor, which looks like this: 


index.html 
index.htm 
index.jsp 

    Try placing a file with one of the above names in your application's document root, and  you'll notice that when you click on the launch link for your 
app, the contents of its welcome page will be served. 

    If your app does not contain any welcome pages, the container would 
    normally generate a directory listing of its docroot folder. By 
    default, this functionality is disabled for security reasons, but can 
    be enabled by setting the init parameter with name "listings" of the 
    "default" Servlet, which is declared in default-web.xml, to "true". 
    This will enable directory listings globally (for all apps). 
    Alternatively, you 
    may enable directory listings for your app only, by setting "listings" to 
    "true" in your app's sun-web.xml descriptor.
