Developer Interview (#DI17) with Alex Soto (@alexsotob) Arquillian, Docker and Testing In Containers

Developer Interview time again. Not a Friday, but it was recorded on one. And because it is so awesome, I decided to push it out as soon as I can. Fellow Arquillian contributor Alex Soto (@alexsotob) found some time to briefly walk us through what Arquillian is, and how it works and deep dives into the new extension called Cube which is an extension that can be used to manager Docker containers from (more...)

What Do Assistant Dogs And Java Have In Common?

You already know, that the RebelLabs team generates awesome content and you might have come across one of their surveys in the past. I occasionally tweet about them, but just recently they launched something which directly went down to my heart.

What do Assistant Dogs And Java Have in Common?
Actually, RebelLabs started to donate money to charities for each completed survey. And this time the survey is all about Java performance, profilers and tooling. (more...)

Deploying applications remotely with WebLogic REST Management Interface

WebLogic 12.1.3 provides a fully documented REST Management Interface that enables deployment and management operations to be performed using REST calls.

The table of contents from the documentation lists the set of operations available:
To use the REST Management Interface, it first must be enabled for a domain. This can be done from the WebLogic Console.

Simple (Effective) Refresh Approach for ADF Regions

I often hear developer asking about how to refresh different regions on the same page, when specific event happens in one of the regions - to refresh dependent regions. Usually developers would like to use something more simple than Contextual Event approach. There is more simple approach, may be it doesn't work for all the possible use cases - but it does it job, when just refresh is needed. This approach is based on dummy (more...)

Indicator for Background REST Service Access with A-Team Mobile Persistence Accelerator

You should check my previous post about Background REST Service Access with A-Team Mobile Persistence Accelerator (AMPA). There I describe how to optimise MAF performance for REST service calls, allow user to continue working with the mobile application, without locking the screen until Web Service response arrives. Steven Davelaar have documented how it works, you can read it in his blog - Calling Web Services in Background Using MAF 2.1.

I have updated sample (more...)

MAF 2.1.1 : Using Local Notifications

One of the new features in version 2.1.1. of Oracle MAF are local notifications. These notifications originate within the MAF application and are received by the same application. They are delivered to the end user through standard mechanisms supported by the mobile device platform (for example, banner, sound) and can work when the application is either in the foreground, background or not

Review: "WildFly Configuration, Deployment, and Administration – Second Edition" by Christopher Ritchie

Travelling has downsides. Especially when coming back to the office to catch up with all the tasks being actively postponed. One of them has been sitting here for too long: It took me a while to get this latest review for Packt Publishing out the door. But this is the good side of traveling, you have plenty of time to read and educate yourself on topics.

Abstract
WildFly 8 is a modular, lightweight, Java EE-compliant (more...)

IBM Bluemix demo using IBM Watson Personality Insights service

The IBM Watson Personality Insights service uses linguistic analysis to extract cognitive and social characteristics from input text such as email, text messages, tweets, forum posts, and more.

Automatic ADF Popup Opening on Fragment Load

I had a post about opening ADF Popup on page load - Opening ADF PopUp on Page Load. Approach is quite straightforward, developer needs to use showPopupBehavior operation with appropriate trigger type. When it comes to ADF Popup opening on fragment load, implementation is a bit more complex. There is a known method to implement hidden text field and in the getter method call your custom logic - getter will be executed when fragment loads. (more...)

Push Notifications and the Internet of Things

Today on Facebook’s F8 conference they announced Parse for IoT. This a cool, but not unexpected move, especially since there is demand to have connected objects being part of an (enterprise) cloud systems. We will see more of that happening soon, and our lesson learned on traditional mobile, will be applied to IoT devices or “connected objects” in general.

AeroGear and IoT

In the AeroGear project we have done similar experiments, bringing functionality of our (more...)

Background REST Service Access with A-Team Mobile Persistence Accelerator

REST service transfers light data, but service execution time could bring significant delay to the enterprise mobile application. I have already introduced you to the A-Team Mobile Persistence Accelerator (AMPA) in previous post - REST Service Access with A-Team Mobile Persistence Accelerator. Based on AMPA author - Steven Davelaar suggestions, I will post today updated application, where REST service call will be handled in background. This will allow mobile user to continue working with the (more...)

Update a grails project from version 2.3.8 to version 2.4.4

At first I changed the version of the application to 2.4.4.
> grails set-grails-version 2.4.4

I also created a new appliction with grails 2.4.4. From this application I took the BuildConfig.groovy and copied the content into to the BuildConfig.groovy of the application I wanted to update. Then I added the changes to the BuildConfig which  are necessary for the application.

In the datasource of the application I (more...)

The Secret Feature of Bucketsets in Oracle Business Rules

In Oracle Business Rules one can use so-called "Bucketsets". I never liked the term as it is not in the dictionary (did you mean bucketseat?), and never understood what is wrong with "list of values" (LoV) as that is what it is.

See for example the following bucketset that defines a list of values to be used for some status field:


Anyway, bucketsets are typically used in decision tables to define the set (more...)
