Create source code for REST service and servlet

File src/main/java/org/allowed/bitarus/TestService.java

URL http://localhost:8080/WebApp/rest/testSvc/asddddd 

   1 package org.allowed.bitarus;
   2 
   3 import javax.ws.rs.GET;
   4 import javax.ws.rs.Path;
   5 import javax.ws.rs.PathParam;
   6 import javax.ws.rs.core.Response;
   7 
   8 @Path("/testSvc")
   9 public class TestService {
  10 
  11     @GET
  12     @Path("/{param}")
  13     public Response getMsg(@PathParam("param") String msg) {
  14         String out = String.format("testSvc returns %s", msg);
  15         return Response.status(200).entity(out).build();
  16     }
  17 
  18 }

File src/main/java/org/allowed/bitarus/Servletx.java

http://localhost:8080/WebApp/servletxxx 

   1 package org.allowed.bitarus;
   2 
   3 import javax.servlet.*;
   4 import javax.servlet.http.*;
   5 import java.io.*;
   6 
   7 public class Servletx extends HttpServlet{
   8     public void service(HttpServletRequest req, HttpServletResponse res) throws IOException
   9     {
  10         res.setContentType("text/html");
  11         PrintWriter out = res.getWriter();
  12         out.println("<html><head><title>Hello World!</title></head>");
  13         out.println("<body><h1>Hello World!</h1></body></html>");
  14     }
  15 }
