Running both vaadin application and REST services with mapping

General
1

Hi,

My vaadin app works default (1 below). However my REST services (2 below) does not work with the same configuration and vice/versa at same time.

  1. vaadin http://localhost:8080/facmulta/

@Theme(“parking”)
@SuppressWarnings(“serial”)
public class MyVaadinUI extends UI
{

@WebServlet(value = "/*", asyncSupported = true)
@VaadinServletConfiguration(productionMode = false, ui = MyVaadinUI.class, widgetset = "ch.oneict.facmulta.vaadin.AppWidgetSet")
public static class Servlet extends TouchKitServlet {
}

@Override
protected void init(VaadinRequest request) {

…

  1. REST http://localhost:8080/facmulta/service/getAllPersonenInXML

Calling the REST http ends up starting the vaadin app not my XML/JSON REST services.
However changing the following my REST works after a restart:

@WebServlet(value = “/", asyncSupported = true)
to
@WebServlet(value = "/ui/”, asyncSupported = true)

Now my REST deliver XML/JSON with the links (my vaadin does not work anymore):

http://localhost:8080/facmulta/service/getAllPersonenInXML
http://localhost:8080/facmulta/service/getAllPersonenInJSON

How can I make this work together?

My web.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?> resteasy org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap Resteasy org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher Resteasy /rest/* resteasy.scan true resteasy.servlet.mapping.prefix / 30

Thanks!

If you move the default /* mapping for a Vaadin application you also need to make sure that Vaadin can find the /VAADIN/* url from where it loads all the static resources.

Have a look at
https://vaadin.com/book/vaadin7/-/page/application.environment.html
 section “Mapping sub-paths”.

You should have

@WebServlet(value = "/*", value = "/VAADIN/*, asyncSupported = true) and make sure nothing else intercepts those requests.

I managed this way:

@WebServlet(urlPatterns = {"/app/*", "/VAADIN/*"}, initParams = {
        @WebInitParam(name = "productionMode", value = "true")})
4

That worked. Thanks! There is a spelling error though… Corrected:
@WebServlet(urlPatterns = {“/app/", "/VAADIN/”}, asyncSupported = true)

Thanks ! See also other reply.

Hi,

I have the same secnario, where i have downloaded vaadin hello world application, for that i have added a Restful service, however, i would not be able to configure the remaining part, how to connect this rest full service to the vaadin application UI. i do not hve web.xml in hellow world app, could you please attache a working sample, with this restfull webservice implementation with vaadin application. i have tried a lot but no luck.

[code]
@Theme(“valo”)
@SuppressWarnings(“serial”)
public class HelloWorldUI extends UI {
private int clickCounter = 0;
private Label clickCounterLabel;

@WebServlet(value = "/*", asyncSupported = true)
@VaadinServletConfiguration(productionMode = false, ui = HelloWorldUI.class)
public static class Servlet extends VaadinServlet {
}
@Override
protected void init(VaadinRequest request) {
    final VerticalLayout layout = new VerticalLayout();
    layout.setMargin(true);
    layout.setSpacing(true);
    setContent(layout);

    layout.addComponent(new Label("Hello World!"));

…
[/code]rest full web service with jersy

import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.core.Response; @Path("/hello") public class HelloWorldService { @GET @Path("/{param}") public Response getMsg(@PathParam("param") String msg) { String output = "Jersey say : " + msg; return Response.status(200).entity(output).build(); } } Here i would like to connect these two, vaadin UI and web service, that would give the out put as follows:

http://localhost:8080/myui - should redirect to the hello world vaadin app ui
http://localhost:8080/rest/hello/ - should call my webservice.

Thanks in Advance!
