David reviewed Wicket in Action by Martijn Dashorst and Eelco Hillenius and gave it 6 out of 10 horseshoes.

For me the information came a little too thick and fast, and assumed more existing knowledge than I already had. ... It is an advantage having this level of knowledge about the architecture and underlying decisions that made Wicket what it is, but I wasn't sure about the order or rate of delivery. ... There is still plenty of in depth knowledge and examples that will benefit any Wicket application, and the later chapters address areas like authorisation, internationalisation and deployment that will make the difference between a good application and a successful one.
