Apache Wicket

Top Pro

Easy way to create reusable panels or layouts

So it is easy to create, maintain or modify a consistent corporate design across all pages. See More

Top Con

Newer versions might break existing code

Top Pro

Separation of code and layout

The HTML templates contain IDs that are references in Java code. There is no code in the templates. See More

Top Pro

Valid links in template can be converted to valid links in output html

That way the IDE, e.g. IDEA can verify the links already in the templates and hence there are less bad links. See More

Vaadin

Top Pro

Top notch documentation

The book of Vaadin is a must have for every developer that uses Vaadin to make web apps. It is an excellent reference manual and all around a great tool for every Vaadin related need. You can find and download the pdf online or get it for free in almost any Vaadin sponsored conference. The online documentation is also very good. It has some tutorials and video guides. There is also a vibrant community which sorround Vaadin, for any problem you may have there is a big chance that someone has already asked and answered that question on StackOverflow or in the Vaadin forums. If not, it will probably be answered quickly if you ask it. See More

Top Con

Quickly gets expensive

$100-890/month for each developer. See More

Top Pro

Easy to develop prototypes quickly

Vaadin has what is called the Vaadin Directory which is a repository of downloadable Vaadin components which can be easily used for development. To use something from the repository, you need to download the JAR file and add it to the project. See More

Top Con

Weak scalability

Since Vaadin stores the UI state and logic in the server, this means that for every user interaction a request needs to be sent to the server and the client needs to wait so it can know how to react. This leads to higher traffic and load times. See More

Top Pro

Compiles Java to JavaScript

Vaadin uses GWT to compile Java code into JavaScript. This means that developers using Vaadin can write both frontend and backend code in Java. See More

Top Pro

Easy to use

Vaadin has a 'design mode' which allows developers to drag and drop components into a canvas and then provide the logic for every component. There are also a lot of third party tutorials and guides which help with the initial learning curve. See More
