Description
This course addresses a key component of the Netscape Application Platform, the Netscape Application Server (NAS), and is specifically targeted at developers who want to understand and implement this technology. This course will begin with an overview of the Server's features and then examine its capabilities and benefits. Next, developing and deploying NAS applications will be covered. Finally, participants will learn about developing data base applications and designing extensions using Netscape Extension Builder.
Audience
This course assumes prior knowledge of Internet standards and Web technologies including: Web application development, forms-based Web applications, CGI (course 12776), Java (courses 12975-77) or C/C++ (courses 13201-10), and relational database technology. In addition, taking Introduction to Netscape Servers (course 85511) would be beneficial.
