Any discussion around user interface capability inherently entails a discussion around mobile enablement. Organizations are making concerted efforts to understand how to develop and extend user experiences to a wide range of mobile devices.
Oracle’s ADF Mobile allows companies to develop leverage the power of declarative development and data binding to enable mobile experiences for new and existing systems.
In this episode of the Enterprise 2.0 Workbench we take a look if using ADF Mobile to create an interface on top of WebCenter Content. We do this using a web service data control that is being generated on top of a Java Bean connecting to Content Server. Our Java Bean uses RIDC to connect to content server and although it is not necessarily best practice to layer a web service on top of a bean using RIDC (RIDC uses services to call into Content Server – creating additional service traffic), it gives us a sense of how we can use existing services or services that are quickly enabled through a plain old job object to create our mobile interfaces.
Simple Example Scenario
In our example to create a mobile interface on top of the sales library to enable our sales people in the field to get the most recent, approved content items to help them do their job.
For organizations looking for true production mobile capabilities for WebCenter Content should review
Let’s dive in and review the various components within our simple example solution.
AMX Mobile Pages
Our solution only consists of two pages. These pages are created using ADF Mobile’s AMX tags. The DocView.amx will recursively call itself if a user chooses to drill into a folder within the interface. If a user selects a document the view will be routed to DocView.amx.
Document List Views – amx:setPropertyListener and amx:listView
For each selection we will store the relevant ID code in a managed bean associated with our application. This is done by including an amx:setPropertyListener within each list item to set the selected node. Once the row is selected, the managed bean’s GetCollection method will be called to refresh the data bound to 2 amx:listView components.
Data Controls used to Create amx:listView
The 2 amx:listView components in the DocView.amx were declaratively based on the following controls that were dragged and dropped into the AMX page. The data controls were created by creating a new “Web Service Data Control” in our project based on a WSDL from our service layer on top of Content Server.
Managed Bean in ADF Mobile
Our managed bean does the heavy lifting in our example. It contains a series of methods that are called from our AMX page using actionListener attributes of our components.
