Answer 1

use the annotation @context (Method level injection)

public Response getContext(@Context HttpServletRequest req, @Context HttpServletResponse res)throws Exception
{   
    System.out.println("Context Path is:"+req.getRequestURL().toString());
    result=req.getRequestURL().toString();
    return Response.status(200).entity(result).build();
}

Answer 2

Use @Context, here is Jersey documentation

@Context
private ServletContext context; 

UPDATED - you can also inject directly into methods if desired

public String uploadNotices(@Context ServletContext context, ...)
