Host Publisher is a set of tools for providing access to data on a legacy data
source (a terminal-oriented host application or database application, for
example) on the World Wide Web or a private intranet. These legacy data
sources typically involve proprietary access and complex applications. Host
Publisher enables you to present end users with the data they need without
exposing the way the data is accessed.
You can use Host Publisher to develop applications that, when published on a
Web application server, enable other people to interact with data on a host. For
example, if you have an existing host application that enables users to look up
employees' telephone numbers, you can create a Web page that lets a user with
a browser enter the name of the person he or she wants, and then displays the
telephone number on another page.
You can use Host Publisher Studio to create Integration Objects, which contain
logic to perform host data access and retrieval tasks using 3270, 5250, and
virtual terminal (VT) data streams and relational databases that provide a Java
Database Connectivity (JDBC) interface such as IBM DB2 Universal
Database™, Oracle, and Sybase. You can then use these Integration Objects to
build more sophisticated Host Publisher applications based on JavaServer Pages
(JSP) pages, servlets, or Enterprise JavaBeans (EJB).
Host Publisher uses IBM WebSphere Application Server to provide a consistent,
reliable execution environment for Host Publisher applications; for example,
servlets or EJB-based applications, and HTML/JSPs across platforms.
Applications created in Host Publisher Studio can be accessed with all standard
Web browsers, with or without Java.
