ADF 12.1.3 : Implementing Default Table Filter Values

In one of my projects I ran into a requirement where the end user needs to be presented with default values in the table filters. This sounds like it is a common requirement, which is easy to implement. However it proved to be not so common, as it is not in the documentation nor are there any Blogpost to be found that talk about this feature. In this blogpost I describe how to implement this. The Use Case Explained Users of the application would typically enter today's date in a table filter in order to get all data that is valid for today. They do this each and every time. In order to facilitate them I want to have the table filter pre-filled with today's date (at the moment of writing July 31st 2015).

ADF 11g Quicky 3 : Adding Error, Info and Warning messages

How can we add a message programatically ? Last week I got this question for the second time in a months time. I decided to write a short blogpost on how this works. Adding messages is very easy, you just need to know how it works. You can add a message to your faces context by creating a new FacesMessage.

When the but

How to: Adding Speech to Oracle Digital Assistant; Talk to me Goose

At Oracle Code One in October, and also on DOAG in Nurnberg Germany in November I presented on how to go beyond your regular chatbot. This presentation contained a part on exposing your Oracle Digital Assistant over Alexa and also a part on face recognition. I finally found the time to blog about it. In this blogpost I will share details of the Alexa implementation in this solution. Typically there are 3 area's of interest which I will explain. Webhook Code to enable communication between Alexa and Oracle Digital Assistant Alexa Digital Assistant (DA) Explaining the Webhook Code The overall setup contains of Alexa, a NodeJS webhook and an Oracle Digital Assistant. The webhook code will be responsible for receiving and transforming the JSON payload from the Alexa request. The transformed will be sent to a webhook configured on Oracle DA. The DA will send its response back to the webhook, which will transform into a format that can be used by an Alexa device. To code
