Fix Version/s: 11.1
> Servlet annotations not working

> Key: NETBEANS-2877
> URL: https://issues.apache.org/jira/browse/NETBEANS-2877
> Project: NetBeans
> Issue Type: Bug
> Environment: Win10, Apache NetBeans IDE 11.0 (Build
> incubator-netbeans-release-404-on-20190319), apache-tomee-webprofile-8.0.0-M3
> or TomCat 9.0.22, or Glassfish 5.0.1
> Reporter: Ernestas Gruodis
> Priority: Major
> Fix For: 11.1
>
>
> Some kind of nightmare - can not launch primitive servlet on
> `apache-tomee-webprofile-8.0.0-M3` (the same with TomCat 9.0.22 and Glassfish
> 5.0.1) and `Apache NetBeans IDE 11.0 (Build
> incubator-netbeans-release-404-on-20190319)` by using servlet annotations..
> Using JDK11. Here is the code:

> import java.io.PrintWriter;
> import javax.servlet.ServletException;
> import javax.servlet.annotation.WebServlet;
> import javax.servlet.http.HttpServlet;
> import javax.servlet.http.HttpServletRequest;
> import javax.servlet.http.HttpServletResponse;
> @WebServlet(name = "NewServlet", urlPatterns =
> {"/meow"}
> )
> public class NewServlet extends HttpServlet {
> /**
> Processes requests for both HTTP <code>GET</code> and <code>POST</code>
> methods.
> * @param request servlet request @param response servlet response @throws
> ServletException if a servlet-specific error occurs @throws IOException if an
> I/O error occurs
> */
> protected void processRequest(HttpServletRequest request,
> HttpServletResponse response)
> throws ServletException, IOException {
> response.setContentType("text/html;charset=UTF-8"); try ( PrintWriter out =
> response.getWriter()) \{ /* TODO output your page here. You may use following
> sample code. */ out.println("<!DOCTYPE html>"); out.println("<html>");
> out.println("<head>"); out.println("<title>Servlet NewServlet</title>");
> out.println("</head>"); out.println("<body>"); out.println("<h1>Servlet
> NewServlet at " + request.getContextPath() + "</h1>");
> out.println("</body>"); out.println("</html>"); }
> }

> The goal is to declare servlets only by annotations, like:
> {code:java}
> @WebServlet(name = "NewServlet", urlPatterns = {"/meow"}){code}
> Tested on NetBeans 8.2 with JDK1.8u221 - all works as expected. I suspect the
> problem is in Apache NetBeans 11, even if project JDK is set to 8 (also
> source/binary format).
