Chapter 14. Oracle Application Server Wireless

As Oracle Application Server has evolved,
new components have extended the standard capabilities of an
application server to handle new areas of technology. One area of
explosive technology growth today is the deployment of
wireless-enabled applications. This growth has been aided by an
increase in the sophistication of wireless devices, including cell
phones and Internet-attachable PDA devices, and the growing
availability of public wireless connection sites. Usage of such
applications and infrastructure is now becoming commonplace. Oracle
Application Server Wireless provides a platform that enables the
deployment of mobile applications.

Of course, the value of OracleAS Wireless applications is that
information can be made available to, and can be updated by, remote
users. Advanced OracleAS Wireless features can enable targeted data
delivery based on device location. For example, you may want to
provide a guide of local movies available in a particular area based
on the current physical location of a person's cell
phone.

The OracleAS Wireless features in Oracle Application Server enable
the deployment of a variety of mobile applications, including:

Browser-based applications

Voice applications

Applications written using Java 2 Micro Edition (J2ME)

Two-way messaging applications using asynchronous services (ASK),
alerts, and notifications

Mobile applications can function entirely disconnected, occasionally
connected, or fully connected, depending on the application.

OracleAS Wireless provides components in three areas:

Foundation services

These services are required in the development and deployment of
wireless applications. Foundation services include location-based
services, alerts, content syndication, provisioning, personalization,
synchronization, analytics (providing mobile usage reports), and
commerce utilities.

Development tools and sample wireless applications

Applications are built using a variety of supported languages and the
OracleAS Wireless Development Kit (WDK).

Support of multiple protocols

These protocols enable access to wireless applications from a variety
of devices. For example, OracleAS Wireless provides the underlying
infrastructure for mobile deployment of Oracle's
Collaboration Suite and E-Business Suite applications.

Deployed applications are accessed using a variety of delivery
methods via the Multi-Channel Server (see Section 14.3 later
in this chapter.

the OracleAS Wireless application development tools, deployment
process, and administration tools.
