I took my old sample application implemented in 2010 – Dynamic Flying Dashboard UI Shell and upgraded it to recent ADF 12.2.1.1. It runs pretty well, without major changes – this proves ADF migration between releases can be smooth (well, not always in practice – but let’s be positive).
I have recorded gif to give you an impression how it runs and how UI switch works in ADF UI panel dashboard component:

There are four blocks in the dashboard, user can remove each of the blocks or select predefined group of blocks: Read the complete article here.

While building a demo of new Oracle ADF features for my OOW session, I came across some nice new functionality in the dvt status meter gauge component (dvt:statusMeterGauge), specifically the round one which has become quite popular in various Oracle Alta UIs.

Turns out you can turn the dial and cut it so it shows just parts of a circle. By adding thresholds you can use it as a replacement for the dial gauge. Here is how it can look:  Here is the code used: Read the complete article here.

Previously I have posted about using dvt:thematicMap to mark locations using latitude and longitude, In that post I have described about showing different cities as markers on a world map using a POJO based data structure
Now In this post I am going to describe that how can we enable selection in thematic map and get selected location value in managed bean so here in this post I am extending that previous application
dvt:thematicMap looks like this after pointing cities markers

Now to enable selection set selection mode to single for dvt:pointDataLayer and create a selection listener method in managed bean. Read the complete article here.

There are some cases when we need to get a value associated to the new value that we have selected in a selectOneChoice, or that we have typed in an inputText.
In this cases we will not be able to get that value, as the only thing we can do is to get the new value from the ValueChangeListener object.
In this example we are going to use HR schema and we will have Employees view object. In DepartmentId field we are going to create a List of Values to show the DepartmentName value in the selectOneChoice.

We are also going to add DepartmentName field from Departments view into Employees view.

If we have to drag and drop the Employees view from the data control palette into our page and create a form.
In DepartmentId field component, we have to set autoSubmit to true and create a valueChangeListener. Read the complete article here.

This post is based on JDEV 12.2.1.1, it seems like there is issue with ADF BC REST custom method definition in this release. I’m glad it is not runtime issue, but related to design time JDEV wizard incorrect functionality. I will explain how to bypass it, when you want to expose custom REST method in 12.2.1.1.
Sample application (ADFBCRestApp_v8.zip) implements custom method, exposed through ADF BC REST – calculateEmployees. This method is created in VO Implementation class and it accepts two parameters – firstName and lastName. Method works correctly, I can execute it through POST, by passing predefined payload with method name and parameters (read more in developer guide – 22.12.5 Executing a Custom Action):

Make sure not to forget to specify Content-Type, otherwise POST request to ADF BC REST will fail: Read the complete article here.

The idea for this OTN ArchBeat podcast was suggested by Oracle ACE Director Mia Urman, a self-described Oracle Forms fanatic. According to Mia, developers have been building mission-critical systems in Oracle Forms for decades, and many organizations have huge investments in these systems. These organizations are now looking for ways to bring these investments forward into mobile, cloud, and other next-generation technologies.

This represents an huge opportunity for experts in relevant Oracle technologies. The discussion captured in this podcast addresses some of the available modernization strategies in order to provide guidance for those who want to take advantage of that opportunity. Mia also selected the panelists for this discussion.

The Conversation

· Listen to Part 1: Many mission-critical applications built on Oracle Forms need to be brought into the 21st century. What are the options?

· Listen to Part 2: A discussion of use cases illustrating modernization strategies for Oracle Forms applications.

· Listen to Part 3: A discussion of how Mobile and other factors that are driving the need for the modernization of Oracle Forms applications.

Listen to Part 4: What factors will affect decisions around the selection of a strategy for modernizing Oracle Forms applications. Listen to the podcasts here

imageIn ADF 12.2.1.1, released a couple of weeks ago, we had many new features as you can see in my previous post ADF 12.2.1.1 has been released: Bug fixes and lots of new features.
One of them is the DVT component Tag Cloud (af:tagCloud).
In this example I am going to show a quick overview of the component. I am going to use Jobs and Employees tables of HR schema.
In order to create the component we just have to drag and drop the desired viewobject into our page and select ‘Tag Cloud’.

In the wizard we have to provide at least 2 fields: ‘Text Value’ that will be de displayed value in the tag cloud and ‘Relative Size’ that will determine the size of each item.
We can also create Grouping rules to make each group to have a different color or to highlight the items of the group when we hover them, etc. Read the complete article here.
