AS/400e Advanced Technology
• Web server error logs will now contain messages in the customer's language of
choice.
• New APIs are provided that allow third-party management tools to query the value of
certain configurations directives, as well as the Web server's mapping rules for a URL.
V4R4 also provides performance improvements in the AS/400 HTTP Server through the
ability to dynamically cache HTML files in memory so that subsequent requests for the same
file can be handled without the need for a file I/O. Support for multi-thread CGI programs can
also provide improved performance of the HTML server with V4R4.
V4R4 provides support for Lightweight Directory Access Protocol (LDAP) in the HTTP Server,
which defines a protocol to access directory services on a network. A new Domino plug-in is
also provided that allows the HTTP Server to access documents stored in Notes.
The AS/400es Web serving capabilities include support for the IBM WebSphere family. There
are several components in the WebSphere family:
• The IBM WebSphere Application Server provides a framework for consistent,
architected linkage between the HTTP requests and business data and logic. IBM
WebSphere Application Server is intended for organizations that want to take
advantage of the productivity, performance advantage, and portability that Java
provides for dynamic Web sites. It includes:
– Java runtime support for server-side Java servlets.
– JavaServer Pages (JSP). A relatively new technology that provides a server-side
scripting technique for generating Web pages. Where Java servlets typically require
the skills of a Java programmer, JavaServer Pages can be created by authors who
have some basic HTML programming skills.
– High-performance connectors to many common back-end databases to reduce the
coding effort required to link dynamic Web pages to real line-of-business data.
– Application services for session and state management.
• The IBM WebSphere Studio, a set of PC-based tools to help developers create
WebSphere applications. The tools currently in the WebSphere Studio are:
– Web Development Workbench: A Web-site project organizer and launch platform.
– Servlet generation wizards: For building Java servlets to access JDBC databases
and JavaBean components.
– VisualAge for Java, Professional Edition V2.0: The IBM award-winning Java
application development environment for building Java applications, applets, servlets,
and JavaBean components.
– NetObjects Fusion: Allows Web-site developers to design and produce an entire
Web site, including individual pages and all links. It features automated site building,
