Wicket vs. ZK
I searched the threads on this forum but didn't find any discussion on comparing Wicket with ZK (www.zkoss.org/), the #1 Ajax project on sourceforge.net now. I read a lot on both frameworks and they both seem nice from the feedback of the users. Since I am about to choose one web framework, I want to get some ideas of these questions here. 1. Design concern (Wicket vs. ZK) Both frameworks are thin-client and generate AJAX, the biggest difference is Wicket uses Java and HTML while ZK uses XUL or other scripting language. What's the advantage and disadvantage in both cases? 2. AJAX components (Wicket vs. ZK) >From the demo websites, it seems ZK provided more AJAX components than Wicket. (As I haven't worked deeply with Wicket, it could be Wicket either provided more components or easy to write those components.) But I am wondering is it easy to use Wicket to implement features like drag and drop, date picker... 3. Target application (Wicket) There is a trend to move from multi-page application to single-page application (or a few pages which much lesser than traditional page-based web application) using AJAX. As far as I know, Wicket is a component-based framework and very OO, which means the components could be well reused and maintained, but is it easy to build such single-page application? Would one or a few more page classes be very large? 4. Integration (Wicket) How about using Wicket together with existing JSF application? Any suggestion on comparing the two freamworks is welcome! Thanks!

Re: Wicket vs. ZK
First, thanks for the reply! >> 2. AJAX components (Wicket vs. ZK) >you do not implement features like drag and drop or datepicker in wicket, >instead you wrap javascript libraries that implement those features with >wicket components. I am actually confused at how many ways Wicket supports AJAX. The classes in wicket.ajax packages are used for AJAX behaviors. I supposed these classes are for common AJAX behaviors. It seems they are different from wrapping JavaScript - correct me if I am wrong. Then my questions are 1) what is the standard way to add AJAX with Wicket: first looking for existing components (including the components in WicketStuff), then if not found, wrap JavaScript? 2) I read the attached file and googled more for the instruction on how to wrap JavaScript. Found one here (http://cwiki.apache.org/WICKET/adding-dynamic-field-prompts-or-hints.html). I am wondering if there are instructions on how to do it in a general way. >>3.

Still not sure, if a page includes many replacement, how to keep the method/class short yet support those changes? >>4.

Absolutely! I started with a simple Wicket page already and will try to add some AJAX stuff tomorrow as well as a page with some replacement. Need to try ZK too. Sounds a lot of fun. -- View this message in context: http://www.nabble.com/Wicket-vs.-ZK-tf4276516.html#a12175176 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Wicket vs. ZK
Hi Eelco, When will the book be published? What version of Wicket it talks about? I am actually would like to view a picture of the achitecture like ZK has in its design documentation. I haven't found it yet. I bet I will learn more along the way I am using it. But it's always nice to have it in mind. I noticed the second chapter of the book is about architecture. Is this the only place for this information? >Btw, it's also a topic that we write a whole chapter about in Wicket >In Action - though that chapter won't be available for a month or so >as we're revising it - so if you sign up for MEAP (nope, it's not >free) you can help use make that chapter perfect by giving us feedback >when it is available :) Thanks, Julie -- View this message in context: http://www.nabble.com/Wicket-vs.-ZK-tf4276516.html#a12188293 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Does anyone develop Wicket app using IRAD and Websphere
It's fairly easy to work with Wicket (1.3 beta2) using Jetty as the web server. However, when I tried to do the same thing using IRAD and Websphere, I always got file not found or Error 404. Then I tried to deploy the wicket-examples-1.3.0-beta2.war to Websphere (6.1.0.2 Build Number: cf20633.22), the example can't work correctly too - got "Error 404: Error reported: 404". Is there anything special need to be set for IBM's stuff? Any suggestion?

Re: Does anyone develop Wicket app using IRAD and Websphere
Hi Martijn, Thanks for the clue! I tried to use WicketServlet instead of WicketFilter in web.xml and it does fix the problem. I don't really know the issue of the WicketFilter or if it's related to the old bug in Websphere 6.0.x as mentioned in other answers (I am using 6.1.0.2). BTW, I just got the question that what's the advantage of using WicketFilter over WicketServlet or if there is any difference behind? Or what pushes Wicket 1.3 to use WicketFilter?

Update a ListView
I have a simple page to that contains an input box, a drop down list with a
submit button and a table below it. When a user inputs something, chooses
the item in the drop down list and hit the submit button, the table should
be refreshed. It seems a lot like the GuestBook in the example.
I first implemented the table with AjaxFallbackDefaultDataTable with a list
of AbstractColumn and it works well. But then I changed to use
PagableListView and couldn't get the table content refreshed.
The code is like this (1, 2 and 3 are in one method, 4 is in another method)
0. In the constructor: initiate the instance variable of messages.
messages = personService.doGetMessages(currentUser);
1. The text area
The model is an Object of Message class.
final IModel messageModel = new CompoundPropertyModel(new
Message());
form.add(new TextArea("message", new PropertyModel(messageModel,
"message")).setRequired(true));
2. The drop down list
The model is an Object of Person class which I retrieved from database.
form.add(new DropDownChoice("receiver",
new PropertyModel(messageModel, "person"),
new LoadableDetachableModel() {
protected Object load() {
return personService.doFindUsers();
}
},
new ChoiceRenderer("formattedName")).setRequired(true));
3. The button
form.add(new Button("sendButton") {
public void onSubmit() {
Message message = (Message) messageModel.getObject();
personService.doSendPersonMessage(message);
message.setMessage("");
messages = personService.doGetMessages(currentUser);
//REFRESH THE LIST
}
});
4. The List View
The model is a list of Message(s)
PageableListView messageListView =
new PageableListView("messageTable", messages, 5) {
protected void populateItem(ListItem item) {
Message message =
(Message)item.getModelObject();
item.add(new Label("messageContent",
message.getMessage()));
}
};
form.add(messageListView);
Question:
a. The messages in the ListView hasn't been refreshed when it is refreshed
in the onSubmit() in the button code. Why?
b. In the button code (#3 in the code list), if I reset the model of the
ListView in onSubmit() as follows to replace the refresh of messages, the
table is refreshed. But I don't think it's the right way to do it, right?
getParent().get("messageTable").setModelObject(personService.doGetMessages(currentUser));
c. What's the difference of using DataTable and ListView in Wicket? If it's
discussed before, please just tell me this.
Thanks!
Julie

Re: Update a ListView (Solved)
Just need to remember only the model get updated for each request. So after I
changed to code as follows, it works!
After:
PageableListView messageListView =
new PageableListView("messageTable", new PropertyModel(this,
"messages"), 5)
Before:
PageableListView messageListView =
new PageableListView("messageTable", messages, 5)
