Usecase: This sample uses a RESTful service which contains a GETmethod that fetches employee details for an employee with given employee IDalong with other methods. The data is fetched in JSON format. This RESTful service is then invoked via ADF Mobile and theJSON data thus obtained is parsed and rendered in mobile in a table. Prerequisite: Download JDev build JDEVADF_11.1.2.4.0_GENERIC_130421.1600.6436.1or higher with mobile support.  Steps: Create a REST service using three...

Quite often, there comes a question in OTN, with different subjects, all meaning "How to call a method when my ADF page loads?". More often, people tend to take the approach of ADF Phase Listener by overriding before/afterPhase methods.In this blog, we will go through different options in achieving it.1. Method Call Activity as default activity in Taskflow :If the application is built with taskflows, then this is the best suited approach to take. 1.a. Calling a Data Control...

In ADF Faces, we can achieve this by setting the autoSubmit property and partialTriggers property for the corresponding columns.However, in ADFdi, we do not have such option. Though we can achieve this by using LOVs and Dependent LOVs. But, in some scenarios we would like to achieve this when using an Input Text...

In normal scenarios, we display the graph and chart to get graphical representation of data. In this article, we'll see how to create graph dynamically by dragging the contents from ADF table and dropping on the graph.Environment : JDeveloper PS5 (11.1.1.6.0)Assuming that we have a table that displays the Department's details. We'll build a dynamic pie graph to display the Employee details for the departments that are dragged from the Department's table. For our usecase, we...
