Advanced JavaServer Pages

David M. Geary is best known for his Graphic Java series from Prentice Hall PTR and Sun Microsystems Press, but for the past two years he has been immersed in server-side Java technology. He is a member of the expert group that's defining the standard JSP technology tag library and is also a key contributor to the Apache Struts JSP technology-based application framework.
