Web Enabling Your HP 3000

Web Dimension
Web Dimension is an application server and a collection of Java components for designing and
deploying web and client/server applications. The main components of Web Dimension are:
• A platform independent application server that can be use with or without a web server. The
application server will deploy site-built applications through web browsers or through the
Web Dimension UI Viewer.
• Java components for building applications and user interfaces. The applications and user
interface pages that are built are actual Java code, but because they are built using the Web
Dimension components, no Java programming is necessary. Assembling and configuring the
components into applications and user interface pages can be accomplished in a number of
visual development environments, including Visual CafÈ and JBuilder. Because the built
applications and user interface pages are Java they, like the application server, are platform
independent.
• A platform independent UI viewer that runs applications from the application server.
Applications can be run through the UI viewer or a web browser. The UI viewer, however,
supports complicated user interfaces not suited for web pages.
Backend Components
Web Dimension includes a several back-end components for building applications. These are a
legacy application access component, a database access component, and a custom object
access component.
The legacy application access component allows Web Dimension applications to use and con-
trol existing HP e3000 legacy applications. An existing legacy application is accessed transpar-
ently through built-in 700/92 emulation. The legacy application requires no changes to be used
by the Web Dimension legacy application access component. Information from the legacy appli-
cation’s user interface can be used in new Web Dimension user interface pages. Web Dimension
user interface pages can also supply input information to the legacy application’s user interface.
There are a number of pre-built Web Dimension applications included that will run typical
HP e3000 legacy applications as-is.
The database access component allows Web Dimension application to access databases through
the JDBC API. Using this component will allow access to many popular databases, such as
TurboImage, Oracle, SQL Server, Informix, Sybase, and DB2.
The custom object access component allows Web Dimension applications to access custom-
built objects. Custom objects can be built in any language and deployed on a number of plat-
forms.
Combinations of any of these components can be used in the same Web Dimension application.
Web Dimension applications can very powerfully combine legacy applications, data, and objects
from a wide variety of computers.
