Servlet path info includes empty string

I have the following servlet:

@WebServlet("/publication/topic/*")
public class ViewTopicPublicationsServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) {
        String[] pathInfo = request.getPathInfo().split("/");
        System.out.println(Arrays.toString(pathInfo));
        ...
    }
}

And for example if I have such url: http://localhost:8080/bulletinboard/publication/topic/SALE

I want to omit empty string. So pathInfo resulted in [SALE] instead of [,SALE]

How this may be achieved ?

Solution

  • You can omit the first character since it's always a slash:

    request.getPathInfo().substring(1).split("/")
