Spring MVC 3.1 can send either JSON or HTML response on the same URL, depending on the type of response requested. With this mechanism, a page can be sent when directly requested from a link, but a JSON response can be sent in response to an AJAX request. This is the controller code: package com.example; import java.util.Map; ... In the above example, JSON response will be sent when the HTTP request contains header "Accept: application/json". HTML response will be sent then the header is "Accept: */*", or "Accept: text/html", or anything else. You can add a limitation that the HTML response does not produce "application/json". But then the question is which response will be sent when the HTTP header is "Accept: */*"? Both methods will...

This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty. <!DOCTYPE HTML> <html> <head> <scrip...

Our custom tag, as implemented in the previous note , is broken when a template is used. Create a template file ( home-template.xhtml ): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric... and a test page that uses it ( home.xhtml ): <?xml version="1.0" encoding="UTF-8"?> <ui:comp...

What's the problem? Our hello tag implementation evaluated the EL with the wrong EL context! This is the corrected implementation: package com.example; import java.io.IOExcep...
