This is part 2 of a series about Wicket.
JDeveloper provides out-of-the-box support for this excellent framework.
For initial setup information you may recall part 1.
Out-of-the-box
Assume the page Hello that of course IS-A WebPage.
package nikos;
import org.apache.wicket.markup.html.WebPage;
public class Hello extends WebPage {
public Hello() {
}
}
To create its HTML file right-click on the project → New… → Web Tier → HTML → HTML Page
In the “Create HTML File” dialog give the name Hello.html, click on “Browse…”
and select the classes/nikos directory.
We’d like a simple page. This is the markup.
<html> <body> <h1 wicket:id="label"></h1> </body> </html>
Thus we don’t specify any value for the <h1> element. Instead we provide a wicket:id. We’ll use this id to get the element and fill its value through Java!
Let’s return to the class for some action.
package nikos;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
public class Hello extends WebPage {
public Hello() {
add(new Label("label", "Hello from Wicket in JDeveloper!"));
}
}
Review
- All the action gets inside this constructor
- Use JDev’s handy “Create HTML File” dialog to place the html in the same directory as the class file.
