Preface

This redbook helps you to understand the functions provided by the IBM

WebSphere Host Publisher Version 3.5 release. It focuses on the architectures

and technologies implemented in this release, and helps you plan, install,

configure and deploy your Host Access applications (3270, 5250) quickly in a

wide variety of environments. In this redbook, you will find information on the

installation, configuration and customization of these applications using the IBM

WebSphere Host Publisher Version 3.5 Studio to create Integration Objects that

can be accessed from JavaServer Pages (JSPs), Java applets, Java servlets,

Java stand-alone applications, Enterprise Java Bean (EJB) applications, XML

applications and desktop Web browsers.

You will also find numerous configuration examples and scenarios showing ways

to set up the IBM WebSphere Host Publisher Version 3.5 server to access host

applications from EJBs. In addition, this redbook provides a good description of

the new Express Logon authentication feature and Remote Integration Object

(RIO) support that allows you to access Integration Objects from client devices

such as Web browsers, Java and XML applications.

A basic knowledge of Java technologies such as servlets, JavaBeans, EJBs,

JavaServer Pages (JSPs), as well as XML applications and the terminology used

in Web publishing, is assumed.
