The Oracle SRDemo Sample Application (ADF BC Version)
Introduction
SRDemo is a moderately complex, data entry application based
around a self service problem and inquiry logging system for a vendor
of household appliances. The application comprises 16 pages, with three
different user perspectives of the application based on security
privileges.
The sample uses JavaServer Faces and ADF Faces components for
the user interface, ADF Business Components for the business service,
and Oracle ADF Model for declarative data binding to integrate the user
interface and the business service.
This sample is the basis of many of the examples used within
the Oracle
ADF Developer's Guide for Forms/4GL Developers and can be
used as a companion to that guide while familiarizing yourself with the
JDeveloper IDE and the Oracle ADF Framework.
Note:
if this is your first time using Oracle ADF, we highly recommend taking
advantage of the companion Oracle
ADF Tutorial for Forms/4GL Developers. It takes you
step-by-step through building a simplified version of this SRDemo
sample application.
Key Features in the Sample
The sample covers a wide range of realistic scenarios and use
cases that a developer using Oracle ADF will typically encounter. These
include:
Maximally Declarative Development — By
combining ADF's entity object, view object, and application module
components, the sample illustrates a business service that exposes
an active data model of SQL queries with reusable business domain logic
built-in so the user interface can be built with little to no code.
Security—The sample is secured
using J2EE container security which is used to divide the application
into functional zones for different user roles as well as configure the
user interface menu etc. to suit the privileges of the connected user.
Ajax—Using the partial page
rendering capabilities of the ADF Faces component set, the sample
removes unnecessary page refreshes when scrolling data-sets and trees
and provides dynamic screens that can respond immediately to operations
such as list of values selection.
ADF Bindings—The sample is
based around screens which use ADF declarative data binding to
integrate with the session facade. All types of bindings are used from
simple method calls to complex hierarchical tree bindings.
MultipleWindows—The
application uses the dialog framework, part of the
ADF Faces component set, to create pop up windows for functions such as
list of values.
Multiple Data Sources—The
primary business service uses ADF Business Components. Additionally the sample uses the new URL data control to access a comma
separated values file as a data-source for the FAQ screen.
Caching—The sample makes
extensive use of the ADF Cache tags to cache static or per session
specific portions of the page and thus improving performance.
Complex Controls—The sample
includes examples of both Shuttle and Tree controls to illustrate the
possibilities for richer user interfaces.
Dynamic Menus—Menus used
throughout the application are defined dynamically and adapt to the
security role of the connected user.
JUnit Testing—The sample is
supplied with unit tests to verify the functionality of the data
integration layer
ANT—Scripts are provided to
install the database schema, build the sample and generate JavaDoc.
Multi-lingual—The sample
application currently supports both English and Italian languages. The
language used will depend on your browser settings.
ADF Faces Skinning—Rather than
being based on the default ADF Faces look and feel, SRDemo uses a
custom skin to provide it's own unique identity.
To successfully install and run the sample you must meet the
following conditions:
The Oracle ADF SRDemo Application (ADF BC Version) sample application requires the
Studio download of Oracle JDeveloper 10g release 3
(10.1.3). Note that the sample will not install under any Early
Access edition of JDeveloper 10.1.3.
Access is required to an Oracle 9i, or 10g
database instance. Any edition of Oracle 10g,
including the Express Edition Beta will work. Oracle Lite is not
supported at this time.
Installing the Sample
The SRDemo sample is available from the JDeveloper update
center on OTN. To download and install the sample:
Choose Help > Check
for Updates from the menu.
In Step 1 of the wizard, ensure that Search Update Centers
is selected and that the option for Official Oracle Extensions
is checked. Click Next.
In Step 2-Available Updates, select the Oracle ADF SRDemo Application (ADF BC Version) option. Click Next and complete the
Wizard
The sample application requires that the JUnit Extension and JUnit
Integration for Business Components extensions are also installed. If
you do not already have these extensions installed within
JDeveloper, selecting the Oracle ADF SRDemo Application (ADF BC Version) extension will
automatically select the dependent ones and you will be prompted to
accept the JUnit license conditions.
You can also download the Oracle ADF SRDemo Application (ADF BC Version) extension manually from here,
and then point the check-for-update to your local file to install the
sample
Once the sample extension is downloaded, you will be prompted
to restart JDeveloper. When JDeveloper restarts the sample installation
process will begin. The install carries out the following tasks.
Unpacks the sample workspace into the
<JDEV_HOME>/jdev/samples/SRDemoSampleADFBC directory.
Creates a database schema called SRDEMO pre-populated with
sample data.
Creates a connection called SRDemo to the above schema.
Once the installation process has completed a readme file will
open in the editor area explaining how to deploy and run the sample,
refresh the database data, and how to remove the sample data and files.
The sample is ready to run immediately.
