David has been using Java since 1998 and involved in using Open Source almost as long. David is a committer on Struts and Commons Validator, but is no longer active on either. He was also the creator of Commons Validator. He has focused on Web and Java EE development and always tries to leverage Open Source projects whenever possible. David started working with Spring 2.0 towards the end of 2006 and really enjoy working with the Spring Framework. He really enjoys it because it not only saves time, but encourages better design and code reuse through loosely coupled components.
David started Spring by Example to post different examples he had been doing at home and also to become involved again with Open Source projects. He opened up the TWiki to the public so people could more easily share different examples they have done. Hopefully Spring by Example will be a general resource for Spring Examples and ultimately save people time.
Currently David works for a financial firm in New York City.
Co-author of Spring In-depth, In Context, which is a free, in progress, online book for the Spring Framework.
Co-author of the validation chapter in Struts in Action: Building Web Applications with the Leading Java Framework, Manning Publications (November 2002).
