Hello Mkyong, Can you please help me, i need some documentation or examples related to Apache Wicket Forms where I can navigate between a flow of screens having Text fields, Drop downs, Back and Next button. I tried a simple example with two screens where i can navigate between the two screens.

Just a comment on how easy, or otherwise, it is to learn Wicket. If you approach Wicket from the perspective of a Spring MVC, JSF, JSP perspective, it is indeed very different. However, the difference is that the concept is actually much simpler.

Wicket attempts to enfore separation of concerns, therefore (almost) no logic whatsoever in the HTML template. This makes the HTML much more readable, especially from the point of view of a Web Designer. The logic is held within the associated Java class, which could be viewed as the ‘Controller’. The design of a Wicket application resembles very Read more ».

Hi, I am a lecturer at the Istanbul Technical University, Computer Engineering Department. One of the courses I teach is 'Database Management Systems' where the students develop a web application using databases as their term project. Until a few years ago we used PHP but then switched to Java in order to be consistent with the course material. Last year we have gone with Wicket as our framework but the students had trouble with finding their way in the documentation. Considering that this is the first course they take after an introductory object-oriented programming course, this year I've decided to prepare a simple tutorial that would teach them how to get started on such a project. The result is on the address: There is also a PDF version: The problem is, I'm a novice Wicket programmer. I would really appreciate all kinds of feedback, especially about the mistakes I might have made in the text or the code.

Models is an obvious example of this. On the other hand, my aim was to focus on the code and explain only the basic issues. Maybe I can give pointers to the reference guide on the Wicket web page for a more detailed explanation. On Thu, Aug 5, 2010 at 10:15 AM, H.

I agree the 'model' is a very powerful concept that needs to be explained properly. However drawing on my own early experiences with with java frameworks I can say that the reasoning for why model's are valuable is difficult to understand until the principals of request lifecycle have been fully explained. The point of a model is to express a dynamic value that is is dependent on the current state of several variables than can change during the course of a single or multiple requests. In the early stages of learning any web front end technology the 'lifecycle' concept is a new one. Jcgarciam wrote.

I would not try explaining all of that stuff to 3rd year students. You can get a good understanding of Wicket without it.

Next to understand a simple request response usecase. Usage of each, if not all controls. How to use them and get it working as is. How would i be able to generalise usage of such controls, can we build a library of such reusable components that this project can use.

By now, I would have had a good understanding of the inner workings if not too deep but to the extent one needs to appreciate it and then build custom components. Next I feel I would use those components where necesary to build the project. What patterns can be used? These are questions I still ask.

I'm planning to include a few more topics like some basic components (selection boxes, radio boxes etc.) and sessions. Other than that, I would like students to figure out some of the stuff themselves.

Of course, depending on our experience next semester, I might reconsider this. Since it's a database course I'm also planning to show examples of using other backends like Berkeley DB, db4o, and Netmind Persistence.
