In the tutorial called Build a Web user interface for an RPG application using iSeries Web Tools you created a simple e-business customer inquiry application that uses a Web-based front end to communicate with RPG business logic residing on an iSeries server. You invoked the Web Interaction wizard to create the input and output pages and to create the servlet to invoke the RPG program or service program to get data from the iSeries database. Next you added this RPG program or service program to the Web application. Finally you tested the application in the local test environment on your workstation. You also created an informative error page for when a customer entered an incorrect customer number.
Here is what the finished e-business customer inquiry application looked like.
After the WebSphere server started, your Web application Customer Inquiry
input page (inquiry.jsp) displayed in the workbench browser.
When you entered a customer number and clicked the Submit push
button, the Customer Details output page (result.jsp) appeared.
Next, you clicked the Back button in the browser to return to the Customer
Inquiry input page. Here you entered an incorrect customer number and
clicked Submit.
An error message appeared.
You then added a new output error page to improve the message information so
that if a wrong customer number was entered,
an error page opened instead of a message.
You have viewed the completed pages of the customer inquiry Web application and now you are ready to begin Exercise 1.2: Introducing the enhanced Web application.
