Apache Wicket - 1.0

Extension ID

com.castsoftware.wicket

What’s new?

Please see Apache Wicket - 1.0 - Release Notes for more information.

Description

This extension provides support for Apache Wicketexternal link - an open source, component oriented, server-side, Java web application framework.

In what situation should you install this extension?

The main purpose of this extension is to improve the transaction path between HTML files that contain Apache Wicket resources (tags within the HTML file) and the Java server-side web framework. The analysis of Apache Wicket therefore also requires that the HTML5 and JavaScript and the JEE Analyzer are installed.

Function Point, Quality and Sizing support

This extension provides the following support:

  • Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
  • Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist
Function Points
(transactions)
Quality and Sizing
(tick) (error)

AIP Core compatibility

This extension is compatible with:

AIP Core release Supported
8.3.x (tick)

Download and installation instructions

The extension will not be automatically downloaded and installed in CAST Console. If you need to use it, should manually install the extension using the Application - Extensions interface.

What results can you expect?

Page initialization: basic support for HTML to Java Constructor

Assuming that the Apache Wicket application is declared correctly and given the following HelloPeople.html file:

html_wicket Expand source

<html>
<body>
    <span wicket:id="message">Message goes here</span>
</body>
</html>

and given the corresponding HelloPeople.java file located in the same folder:

java_wicket Expand source

package com.example;

import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.request.mapper.parameter.PageParameters;

public class HelloPeople extends WebPage {
    public HelloPeople(PageParameters params) {
        String username = params.get("user").toString();
        add(new Label("message", "Bonjour " + username + "!!!!"));
    }
}

Results in Enlighten are :

Java classes can contain multiple Java Constructors. In this situation, the extension will produce a callLink from the HTML5 source code object to each of the explicitly defined Java Constructors objects as follows:

CallLinks between HTML5 source code and Java Constructors are triggered when the path of the HTML object matches the package name of the Java Constructor.

For this result the current extension adds the following Objects, Links and Properties:

Objects

None

Caller Caller name Type of Link Callee Callee name
HTML5 source code HelloPeople.html callLink Public Java Constructor HomePeople

Properties

Object Object name Property name Property value
HTML5 source code HelloPeople.html Use Apache Wicket (1 if Yes)  1
HTML5 source code HelloPeople.html Wicket Ids with Positions message#(3,1,3,48)
Public Java Constructor HelloPeople Use Apache Wicket (1 if Yes)  1

Page initialization and Detach: Basic support for HTML to onInitialize and onDetach methods

Initialization of the page can also be done through the API java methods onInitialize and onDetach. For the following java code file named SignInPage.java and knowing that the BootstrapBasePage class inherits from the org.apache.wicket.markup.html.WebPage class: 

java_wicket Expand source

public class SignInPage extends BootstrapBasePage {
    private String username;
    private String password;
    
    @Override
    protected void onInitialize() {
        super.onInitialize();
        
        StatelessForm form = new StatelessForm("form"){
            @Override
            protected void onSubmit() {
                if(Strings.isEmpty(username) || Strings.isEmpty(password))
                    return;
                
                boolean authResult = AuthenticatedWebSession.get().signIn(username, password);
                
                if(authResult){
                    continueToOriginalDestination();
                    setResponsePage(Application.get().getHomePage());
                }else{
                    error("Username and password are not equal!");
                }
            }
        };
        
        form.setDefaultModel(new CompoundPropertyModel(this));
        
        form.add(new TextField("username"));
        form.add(new PasswordTextField("password"));
        
        form.add(new FeedbackPanel("feedbackPanel"));
        add(form);
    }
}

    public HomePage(final PageParameters parameters) {

Apache Wicket Event Handler modelization

Whenever a call to a method adding elements to an Apache Wicket Java class (Java class that inherits any class that contains “org.apache.wicket”)  is found in the source code, this extension evaluates the name of the wicket_id in which the operation is made and a corresponding object is created. 

If the evaluation of the wicket_id name fails (either due to missing information in the source code or to limitations in the evaluation) no object Apache Wicket Event Handler will be created.

Methods triggering an evaluation of wicket_id are:

Classes Methods
org.apache.wicket.Component add
org.apache.wicket.markup.html.form.Form add
org.apache.wicket.markup.html.form.FormComponent add
org.apache.wicket.page.PartialPageUpdate add
org.apache.wicket.MarkupContainer add
addOrReplace
org.apache.wicket.ajax.markup.html.AjaxLink add
org.apache.wicket.extensions.ajax.markup.html.IndicatingAjaxLink add
org.apache.wicket.markup.html.form.RadioChoice add
org.apache.wicket.ajax.AjaxRequestHandler add
org.apache.wicket.markup.html.WebMarkupContainer add
org.apache.wicket.core.request.handler.IPartialPageRequestHandler add

Supported Handler methods

Following methods of the Apache Wicket API are the supported Handler methods:

Handler method Fully Supported
onClick (tick)
onSubmit (tick)
onUpdate (error)
onEvent (error)
  • An Apache Wicket Event Handler object will be created only if a Supported Handler is declared explicitly and is an override of the Apache Wicket API.
  • The onUpdate and onEvent Handlers are partially supported: Apache Wicket Event Handler Objects will be created, however links from HTML5 source code to Apache Wicket Event Handler might be missing.
