Ebusiness made easy

By Jim Mason and Dave Slater

In the beginning, Web application development was 
difficult. You needed to know how to create your own Web 
pages using HTML, and you needed to understand CGI to 
access data and applications.

There were enhancements along the way: tools to help 
design Web pages and other Web programming languages such 
as Net.Data.

The introduction of Java made programming Internet 
applications easier. Java applications were much more 
portable than applications written in any of the previous 
portable languages. Write Once, Run Anywhere became the 
selling point for Java applications. Java applications 
would run on any platform that supported a Java virtual 
machine (JVM) -- and every strategic hardware platform 
had JVM support. There was a price, however. There were 
books published about learning Java in several weeks, but 
object-oriented (OO) design and programming, and becoming 
proficient at abstraction and inheritance, took most 
programmers six to 12 months to master. Many 
organizations couldn't afford this investment in 
ebusiness application development. Some businesses hired 
new Java programmers for ebusiness application 
development, but many of those new programmers lacked the 
business understanding to create good ebusiness 
applications. Understanding Java and Web programming 
wasn't sufficient.

With the introduction of WebSphere Development Studio for 
iSeries, moving iSeries applications to the Web became a 
lot easier. The WebFacing Tool creates a Web interface to 
existing 5250 applications. The tool creates JavaServer 
Pages (JSP) files, Java beans and servlets based on the 
5250 display file DDS. There is little or no change to 
the business logic of the original application, and the 
"WebFaced" application supports both a 5250 and Web 
interface. The JSP file, servlet and Java beans run on 
WebSphere Application Server, Standard Edition, a free 
feature of OS/400. Programmers will be able to move their 
iSeries applications to the Web easily and cost-
effectively with minimal investment in skills 
development.

How difficult is the WebFacing Tool conversion process?

Here are the steps for conversion: 

1. Check your DDS source to determine whether all of the 
important DDS keywords are supported by the WebFacing 
Tool.

2. Update your DDS source to use only the supported 
keywords or delay your conversion.

3. Set up WebSphere Application Server. 
*  Rochester has set up a first install center pilot 
program for WebSphere Application Server. This support 
from Rochester makes this step relatively painless. 
Contact Joe Druga at 1-507-286-6400 or Pam Sclafani at
1-914-784-5463 for more information.
Start the WebFacing Tool Integrated Development 
Environment.
* Create a new WebFacing project.
* Select a server.

4. Select the DDS file source.

5. Select the presentation style for the Web interface.
* Choose from several style sheets. 

6. Select the commands for calling your application.

7. Convert your application.

8. Deploy your Web application to WebSphere Application 
Server.
* Generate your publishing information.
* Generate the output.
* Deploy to the server.

9. Call your Web application from the browser.

You're done! And if you had WebSphere Application Server 
running and you used only supported DDS keywords, this 
entire conversion process could have taken as little as 
two hours.

How do I begin?

The conversion process is easy, but some training is 
still required. You need to become familiar with the 
following products:

* WebSphere Application Server for iSeries: You need to 
know how to install, configure, administer and tune the 
performance of WebSphere Application Server 

* WebFacing Tool: The education for this tool is combined 
with the education for WebSphere Studio for iSeries 
because many developers want to understand how they can 
enhance and customize the output of the WebFacing Tool.

* CODE: CODE is the preferred development environment for 
creating iSeries applications. There are enhancements to 
CODE to make the WebFacing conversion process easier. 

With two weeks of training, most developers have the 
background to start moving their applications to the Web.

Another option

Many organizations don't have sufficient resources to 
move their portfolio of applications to the Web. For 
these organizations there are conversion services 
available through IBM and the partner community. These 
services offerings include the following:
* Education and training
* Proof of concept conversion
* The conversion of a typical but small application to 
demonstrate the capabilities of the WebFacing Tool
* Turnkey application conversion
* Conversion of your entire portfolio of applications
* WebSphere Application Server set up
* DDS analysis and update
* Application conversion and three-stage publishing; unit 
test, quality assurance and production
* Web application configuration, administration and 
performance tuning

The future is bright

Ebusiness is the future of the IT industry. The server 
with the most ebusiness solutions will be the premier 
ebusiness and Java server. By definition, good ebusiness 
applications have two basic characteristics:
* They are good business applications
* They have a Web interface

The future looks bright for the iSeries server. The 
iSeries server has more good business applications than 
any other server, and the WebFacing Tool can take these 
solutions to the Web quickly, easily and cost-
effectively.

Title: The Ultimate IBM VisualAge for Java Tutorial, Step 
by Step--Visual Programming Made Easy, Second Edition    
Author: Bill O'Farrell
Description: This tutorial helps you to do the following: 
understand the product's integrated development environment 
(IDE), use IDE windows to create new applications and applets, use 
Abstract Window Toolkit and Swing components, drop visual 
and nonvisual component Beans onto the composition 
surface, use the BeanInfo page to generate new class 
features, generate and test code, set break points and 
debug the code with the debugger, and use the Servlet 
Smart Guide to create a simple servlet that accesses a 
Bean and calls a JavaServer Page(JSP).
