Creating Website with the use of template in Wicket

In the previous section of Wicket tutorial you have studied about "printing Hello World", "creating Ajax Auto Completer" and some others very beautiful examples now in this section of Wicket tutorial we are going to describe you how you can create a website by creating templates of it.

In this section of Wicket tutorial we have created a website by using the template and it consists of four links as follows:

Home
Services
About Us
Contact

It consists one header and one footer which will remain same for all nothing will change but the content or page content will be changed according to links. For creating website we have three files as follows:

WebSite.java
WebSite.html
WebsiteApplication.java and according to links we have created four java files more and they have HTML files correspondingly. These files are :

Home.java
Home.html
Services.java
Services.html
AboutUs.java
AboutUs.html
Contact.java
Contact.html

WebSite class file extends WebPage and it contains all the links and when these links are clicked then WebSite class calls its different page's class such as Home.class, Services.class, AboutUs.class, Contact.class.

Here is the full code of WebSite.java


package com.roseindia.wicket;



import org.apache.wicket.markup.html.WebPage;

import org.apache.wicket.markup.html.link.BookmarkablePageLink;



public class WebSite extends WebPage{

 public WebSite(){

  add(new BookmarkablePageLink("homeLink", Home.class));

  add(new BookmarkablePageLink("servicesLink", Services.class));

  add(new BookmarkablePageLink("aboutUsLink", AboutUs.class));

  add(new BookmarkablePageLink("contactLink", Contact.class));

  }

}

corresponding to WebSite.java its HTML file WebSite.html is as follows:


<html>

  <head>

  <title>Wicket Example -Website</title>

  <style>

a:hover{

  background:orange;

  text-decoration:none;

}



#content {

  </tr>

  </table>

  <div id="footer" class="borderedBlock">

  </div>

 </wicket>

  </body>

Roseindia is one of the renowned online publishing and software 

development companies. We render online tutorials and web services.

 We have a vivid expertise in creating vanguard applications on 

Java Server Faces (JSF) architecture.



JavaServer Faces (JSF) is an advanced Java framework for building

 Web applications. It provides a component-centric approach to 

develop Java Web user interfaces by deploying. The web applications

 handle all of the complexity of managing the user interface with 

the power of JavaServer Faces technology on the server, allowing the 

application developer to focus on their application code.



We have deployed complex solutions for our clients based on JSF 

framework. We have ingeniously provided a significant savings on

 the application development cost and manageability to them. However,

for rapid application deployment, we recommend JSF Framework to our clients.

One most important thing to do with this example application is that we have to do the mapping of WebsiteApplication class mapping into the XML file web.xml.

<filter>
<filter-name>WebsiteApplication</filter-name>
<filter-class>
org.apache.wicket.protocol.http.WicketFilter
</filter-class>
<init-param>
<param-name>applicationClassName</param-name>
<param-value>
com.roseindia.wicket.WebsiteApplication
</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>WebsiteApplication</filter-name>
<url-pattern>/wicket/website/*</url-pattern>
</filter-mapping>

To run this example start your Web Server and type the following URL into web browser address bar:
http://localhost:8080/WicketExample/wicket/website

Output:

Home Page
