JPaS Demo

JPaS is a nano framework for creating traditional multi-page web apps in Java. Read more

Examples:

Display smartphone page:

link 1
link 2
link 3

JPaS supports three ways of including parameters in URL:

Link 1 href attribute looks like this: /jpas/demo?page=smartphone&id=000001 it is a traditional way to send parameters in GET request.
Link 2 href attribute looks like the follow /jpas/demo/page/smartphone/id/000001 it is a "static" URL loved by Google and generally preferable. Notice, that page is required parameter that defines html template file.
Link 3 href attribute looks like the follow /jpas/demo/smartphone/000001 Parameters names was removed. Now, page parameter should always be first, just after servlet context.


Here is the server-side code:

    public class SmartphoneView implements JpasView {
    @Override
    public String createHtml(HttpServletRequest request, HttpServletResponse response, Map<String, String[]> params, Document doc, JpasModel model) {

        //url contains parameters names - Link 1 and Link 2
        //String smartphoneId = params.get("id")[0];
        //url does not contains parameter names - Link 3
        String smartphoneId = params.get("param1")[0];
        
        Smartphone phone = ((SmartphoneModel) model).getSmartphoneById(smartphoneId);

        doc.select("head title").first().text(phone.title);

        doc.select("#title h2").first().text(phone.title);
        doc.select("#releaseDate h2").first().text(phone.releaseDate);
        doc.select("#memory h2").first().text(phone.memory);

        doc.select("#processor span").first().text(phone.processor);
        doc.select("#display span").first().text(phone.display);
        doc.select("#battery span").first().text(phone.battery);
        doc.select("#camera span").first().text(phone.camera);
        doc.select("#os span").first().text(phone.os);

        return doc.toString();
    }
}
