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:

  1. Home
  2. Services
  3. About Us
  4. 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 :
  1. Home.java
  2. Home.html
  3. Services.java
  4. Services.html
  5. AboutUs.java
  6. AboutUs.html
  7. Contact.java
  8. 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;
    font-size:14;

 height: 120px;

}

#content {
 vertical-align: top;
 width: 80%;
 height: 100%;
}

#footer {

}
</style>
  </head>
  <body>
  <wicket>
   <div id="header" class="borderedBlock">

     </table>
   </div>
    <table width="100%">
      <tr>
        <td id="left" class="borderedBlock">

         </ul>
        </td>
        <td id="content" class="borderedBlock">
             <wicket:child/>
        </td>
      </tr>
    </table>
    <div id="footer" class="borderedBlock">

    </div>
   </wicket>
  </body>
</html>

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

Services Page
