iSeries Access for Web V5R2 and WebSphere Host Publisher V4.0

Chapter 6. Using Host Publisher Studio to develop J2EE applications 213

Host Publisher Web Services support differs from programming with Integration Objects

because only the following method is used to create the Web Service:

IONamePropertiesObjectSuffix processWSRequest(IONamePropertiesObjectSuffix) throws

BeanException

The processWSRequest method is contained in the helper object when Create Web Services

support is selected on the Host Access or Database Access Options menu. The

IONamePropertiesObjectSuffix

object contains the input and output of an Integration Object.

This object is passed to and from the Web Services processWSRequest method. It contains

getter and setter methods, but no additional methods.

The processWSRequest method takes the properties object as input, drives the Integration

Object with those input properties, and returns the output properties of the Integration Object

through a new instance of the properties object. The advantage of using the

processWSRequest method is that it provides a single method that sets all inputs, drives the

Integration Object, and returns all outputs.

6.8.2 Creating and deploying a Web Service

To create an Integration Object in Host Publisher and then enable it to become a Web

Service, perform the following steps:

1. Using Host Publisher Studio, create one or more Integration Objects or EJB access beans.

Click Options-> Create Web Services Integration Object Support (Figure 6-84).

Figure 6-84 Web Services support

2. Import the Web Services Integration Objects or EJB access beans into Application

Integrator. Create an application that consists of Web Services Integration Objects, EJB

access beans, or both, and then generate an EAR file for the application. Click File->

Create J2EE Archives.

3. Import the EAR file into a J2EE-enabled WebSphere Studio tool, such as WebSphere

Studio Application Developer.
