Hall (computer science, Johns Hopkins University) details the advanced features and capabilities provided by servlets
and JavaServer Pages (JSP).
The O'Reilly Java Conference will focus on key technologies for developing large-scale Java applications including: Enterprise Java Beans; Servlets
and Java Server Pages; Java and XML; Security in Java applications; and Client-side user interfaces.
