This version supports Apache Click 2.2.0 and fixed some issues.
Enjoy Click!
ClickIDE 2.1.0.0 is now available!
This version is the first release of ClickIDE from Apache Software Foundation and it supports Eclipse 3.5 and Apache Click 2.1.0.
You can download it from the following link:

Enjoy Click!
I added Toggle Comment action to the Velocity editor. You can toggle comment for selected lines by the context menu or CTRL + /.
ClickIDE is an Eclipse/WTP plug-in for web application development using Click. This release has not new features however it supports Click 1.5 and Eclipse 3.4/WTP 3.0.
Please download ClickIDE 2.1.0 and enjoy Click!!
Url Rewrite Filter has a configuretion file WEB-INF/urlrewrite.xml. This is a very simple example of clean URL with a Click application.
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite
PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"
"http://tuckey.org/res/dtds/urlrewrite2.6.dtd">
<urlrewrite>
<rule>
<from>^/contents/([0-9]+).htm$</from>
<to type="forward">/content.html?contentId=$1</to>
</rule>
</urlrewrite>
For example, Url Rewrite Filter will forward /contents/001.htm to /content.htm?contentId=001.
If content.htm has possibility to receive any other query parameters, we can define following rules.
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite
PUBLIC "-//tuckey.org//DTD UrlRewrite 2.6//EN"
"http://tuckey.org/res/dtds/urlrewrite2.6.dtd">
<urlrewrite>
<!-- No Query String -->
<rule>
<from>^/contents/([0-9]+).htm$</from>
<to type="forward">/content.html?contentId=$1</to>
</rule>
<!-- With Query String -->
<rule>
<from>^/contents/([0-9]+).htm?(.+)$</from>
<to type="forward">/content.html?contentId=$1&$2</to>
</rule>
</urlrewrite>
Of course, we can use Url Write Filter with other frameworks such as Struts. I think Url Write Filter is a simple solution to make clean URL in the Java web applications.
For example, see the below page class. If you clicks AjaxRequestButton, Click invokes getAllBooks() using XMLHttpRequest. And getAllBooks() renders a Java object as JSON. AjaxRequestButton generates a HTML button that invokes Ajax.Request of prototype.js.
public class AjaxPage extends AjaxPage {
public AjaxRequestButton button
= new AjaxRequestButton("search", this, "getAllBooks");
public AjaxPage(){
button.addAjaxHandler(
AjaxRequestButton.ON_COMPLETE, "displayResult");
}
public boolean getAllBooks(){
List<Book> books = bookService.getAllBooks();
renderJSON(books);
return false;
}
}
Next example. AjaxSubmit control send Form using Ajax.Request.
public class AjaxPage extends AjaxPage {
public Form form = new Form("form");
private TextField keyword = new TextFiled("keyword");
private AjaxSubmit search = new AjaxSubmit("search", this, "onSearch");
public AjaxPage(){
form.add(keyword);
form.add(search);
}
public boolean onSearch(){
List<Book> bookList = bookService.search(keyword.getValue());
renderJSON(books);
return false;
}
}
Of course, these controls need more improvement. However I think this concept matches to Click Framework well.
However I will introduce S2Click detailed features in this blog. And also I will feedback these features to Click Framework from S2Click in the feature.
This is the first step of introducing Click Framework to many Java developers. I'll make effort to incubate Click Framework in the Apache Incubator.
However Click maps page classes to request-path from HTML templates. So page classes which do not have corresponded HTML template is not mapped automatically.
For example:
@Path("/file-download.htm")
public class FileDonwloadPage extends Page {
/**
* Writes response for file downloading in this method.
*/
@Override public void onRender() {
HttpServletResponse res = getContext().getResponse();
OutputStream out = res.getOutputStream();
...
}
/**
* This method returns null to not render template,
* because this class writes response contents for file download.
*/
public String getPath(){
return null;
}
}
This is one idea of using annotation in Click Framework.
JJUG Cross Community Conference 2008 Spring will be held at Japan 30 Apr.
JJUG is an abbreviation of Japan Java User Group. In this conference, top Java engineers in Japan talk about hot topics in Java such as Web frameworks, EclipseLink, JAM, Scala and New Swing APIs.
I'll talk about Click Framework in this conference and join panel discussion with speakers of Grails, JRuby on Rails and Wicket.
I wish to make efforts to spread Click Framework in Japan.
Click Framework provides FileField to upload file, however Click does not provide any support for file downloading. I made AbstractDownloadPage to download file.
Usage:
public class SampleDownloadPage extends AbstractDownloadPage {
public SampleDownloadPage(){
setFileName("sample.txt");
setContents(SampleDownloadPage.class.getResourceAsStream("sample.txt"));
}
}
This page class does not have a template because response is written by this class. So auto-mapping does not work for file download pages. The extended page class have to be registered to click.xml.
Click controls provide JavaScript validation, but they are not easy to customize. Now I'm writing JavaScript validation framework for Click using LiveValidation.
In the page class, ready the LivaValiator control like below:
Form form = new Form("form");
form.add(new TextField("name", true));
form.add(new PasswordField("password", true));
form.add(new Submit("login"));
addControl(new LivaValidator("validator", form));
In the page template, generates LiveValidation JavaScript code by the LiveValidator control:
<body>
$form
<script type="text/javascript">
$validator
</script>
</body>
We can also add customized validation rules by use of Validate.Custom.
