Why use Host On-Demand?
There are a number of reasons to use Host On-Demand:
A cost-effective approach
You can save money in product deployment and maintenance by installing Host
On-Demand on a Web server, eliminating the need to manage individual user
desktops. Users can connect directly to a host system, such as an IBM iSeries
system or an IBM zSeries system, eliminating the need for extra hardware and
software required by connecting back through the Web server. Host On-Demand
can be installed on nearly any server platform, accommodating various size
organizations and branch offices.
Host On-Demand uses a Java applet, which helps to reduce your software
maintenance costs and allows easy management of configuration data. Since the
applets reside on a server and are downloaded to Web browsers when needed, you
no longer have to schedule maintenance and upgrades. Upgrade the software on
the server and users receive the upgrade the next time they request the applet. You
can control the rate of this upgrade as needed. And server maintenance is less
complex with Web-based remote configuration and administration.
Host On-Demand includes a deployment wizard, which enables you to create
custom HTML pages. These pages can tailor the content and function of sessions to
meet the needs of specific groups of users.
Create new e-business applications
Host On-Demand provides a rich tool set to deliver custom e-business applications
that meet your specific business needs. These tools include the Host Access Class
Library API, Host Access Beans for Java and ActiveX controls.
The Host Access Class Library API provides access to 3270, 5250 and VT data
streams. These class libraries allow you to use mission-critical information in new
ways, such as integrating data from one application into another.
Host Access Beans for Java provides host connectivity and emulator functions
through simple, component-based development tools, like IBM Visual Age for Java.
You can use these beans to rapidly create custom applications that allow you to
deliver the specific functions you want to include in your host access applications.
These object oriented beans help you minimize development efforts through
software reuse. Application developers who are familiar with ActiveX can use IBM
Host Access Controls - a set of ActiveX controls used to provide the functionality
found in Host Access Beans for Java.
The Host On-Demand J2EE Connector provides host connectivity functions for use
on a J2EE-compatible Web application server such as the WebSphere Application
Server Enterprise Edition.
Connect directly to any Telnet server
Emulation function is contained in the client applet, eliminating the need for a
middle tier server as part of the connection to the host system, which is both a
performance and security issue. Once the applet is served to the client, it is easy to
