Web crawling????

Vaadin 6 / 7 / 8
1

Hello , Im having problems undestanding how to use the web crawling on a vaadin aplication, i have already read the documentation on Book of Vaadin (https://vaadin.com/docs/-/part/framework/advanced/advanced-urifu.html) But I dont undestand If I’m using it right, here is what I want to accomplish:

We want that google could locate some products on our app, for example if one entes on this link: http://myapp.com/market#!market-item/12345
This link should open the product description page.

But according to the book of vaadin I need to enable (override) the method service on the vaadinservlet to tell the search engines the links of where to look for info in my application, :

@Override
protected void service(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
String fragment = request .getParameter(“idworkflow”);
if (fragment != null) {
Product myProduct = ProductApi.get(fragment);
ArrayList allProducts = ProductApi.get();
Writer writer = response.getWriter(); writer.append(“”+ “

Here is some information about product: “+myProduct.getName()+”

”);
writer.append(“
    ”);
    for(Product p : allProducts)
    {
    writer.append(“
  • ”+p.getName+“
    • ”);
    }
    writer.append(“
”);
writer.append(“”);
}else {
super.service(request, response);
}
}

example:
http://myapp.com/market?idproduct=12345

This will write the next:

Here is some information about Product 12345,
