Easy Steps to Internet Programming for the AS/400, iSeries, and System i
by Hideyuki Yahagi
Book Description
In
recent years, Web technology has become so popular that people use the
Web to search information, reserve tickets, bid for an item on an
online auction, and so on. Quite a number of companies utilize the Web
not only for the Internet but also Intranet and Extranet. The same
applies to companies that use OS/400 as their enterprise system. Users
and programmers can benefit from Web technologies as they add new
capability to OS/400 applications. OS/400 itself has been capable to
run TCP/IP and Web server for years. V3R1 (OS/400 grew out of S/38 at
this version, in my opinion) introduced ILE (Integrated Language
Environment) and IFS (Integrated File System). It would be fair to say
that most OS/400s in existence are quite "Web ready" because HTTP
server (V3R2/7), Native Java (V4R2) and other Web technologies are
already available and bundled with OS/400 at no extra charge.
However,
in OS/400 (and 5250) based companies, migration to Web applications
have been somewhat unfamiliar because of several reasons. For instance,
5250 interface is good enough, OS/400 programmers are not used to Web
programming, and other factors (slow communication infrastructure,
additional investment required to run a Web application server,
availability of Web-based packages and development tools, and so on).
Regardless
of these factors, Web applications are steadily spreading among
midrange customers. In addition, there are factors pushing OS/400 shops
to the Web. such as improved productivity through Web-based software
packages and development tools, adequately resourced computing
environments relating to high performance hardware at affordable cost,
high-speed bandwidth, remote access by cell phone or xDLS, and freedom
from the costly 5250 interactive feature.
OS/400
does not force the either/or situation to customers. It is popular to
use core 5250 applications untouched and develop new applications using
Web technologies or migrate applications to Web interface step-by-step,
rather than all at once. Apparently, the 5250 interface will not go out
disappear as long as OS/400 exists. System operators and experienced
programmers may continue to work with the 5250 interface far into the
future. In the meantime, however, main applications are migrating to
Web interface.
Though
there is no doubt that the Web is the primary way to go, Each company
should formulate a long-term blueprint on their IT roadmap. IT and
business are inseparably related. In other words, a company must
establish its strategy based on considering future criteria and
objectives for both areas.
This
book is written as first step guide for those who consider building Web
applications on their OS/400. It introduces the basic concepts of
various Web technologies, OS/400 adaptation of the technologies, sample
code (from "Hello World" to practical fast to deploy applications) and
plenty of programming tips. Advanced topics that are not covered by
this book can be found in the Web site introduced in this book. The
examples are designed to work in most environments by exploiting
base-functions of operating systems and free tools downloadable from
the Internet.
Contents:
1. Getting Started
This
chapter introduces basic concept of the Internet and TCP/IP. The
chapter quickly goes through the TCP/IP capability of OS/400 and covers
the minimum configurations to utilizing OS/400 as a Web server.
2. CGI Programming
Common
Gateway Interface (CGI) is the most popular way to provide dynamic Web
application. You will learn how to create simple ITEM Query CGI
programs written in ILE-RPG/COBOL/C. Also, I take an in-depth look at
CGI mechanisms to create more complex Multi Conditional Query CGI
programs.
3. Web Programming Using Non-ILE Languages
It
is possible to create a Web application by using various languages. I
take Java (with Tomcat Web application server), Net.Data, and Perl in
this chapter and explain how to install, configure, and use each
language environment to create Web applications.
4. Open System Programming with ILE-RPG
Emergence
of ILE concepts brought enormous capability to the RPG language.
ILE-RPG is far advanced from report generator. It is a general-purpose,
multifunctional programming language. This chapter shows how to use
open APIs from ILE-RPG and introduces ILE RPG for Web-related
technologies such as stream I/O, character code conversion,
create/parse XML file, and socket communication.
5. Porting Open-Source Utilities
OS/400
is an open operating system that can take advantage of a variety of
open-source software on the Internet. If the software conforms to POSIX
specifications and does not use some functions (such as GUI, cursor
control), it is not difficult to port it to OS/400. In this chapter,
after showing how to port POSIX software to OS/400, I exhibit some
practical tools that are ported for OS/400.
6. Internet Mail
E-mail
is one of the most popular Web applications to communicate with people
around the world. In this chapter, I examine e-mail capability of
OS/400 and show how to use e-mail in combination with OS/400
applications.
7. Miscellaneous CGI Techniques
Thus
far, wide-ranging information on Web technologies and related Web
applications are described. This chapter covers tips and techniques to
build a full-blown Web application and, explains more complicated Web
applications in detail.
