How to retrieve servlet context at initialization stage in a war package?

[Christian MICHON]

Hi,

I've been toying with spark 2.2 and trying to deploy a small war webapp with latest tomcat8.

I'm trying to access the servlet context and paths using getServletContext(), which can only be used if the class extends HttpServlet.

I was hoping to write something like this:

public class Main extends HttpServlet implements SparkApplication {

  public void init() {

    System.out.println(getServletContext()); // this does not work the filter will never start inside tomcat8

    get("/hello", (request, response) -> {

      return "Hello World!";

    });

  }

}

Can someone help me untangle this problem? I need this to be able to open some local files within the application, once deployed and expanded in tomcat8/webapps.

Thanks in advance.

1. request.session().raw().getServletContext()
or
2. Have a implement ContextListner to get the ServletContextEvent, from they you can get ServletContext
or
3. I just could not remember now, saw some code, get the ServletContext through Reflection.

I have not tried these, just my thoughts....

I did nb 1 but it needs a request.
Nb 2 looks very promising.

Thanks

solution 2 was the perfect fit for my needs. Thanks Salai!
