In this post I describe how I implemented an interesting Use Case where the customer wanted to have an alternate message in the LOV when there is no data found. We all know how this can be changed in an af:table component by simply changing the emptyText property. In a List of Values, this works 'slightly' different. Lets start with the basics By default you will see the following List Of
Over the last couple of years, or better in the last decade I have implemented several reporting solutions with Jasper Reports in ADF. I did that in ADF 10g, ADF 11.1.1.x, ADF 11.1.2.x and ADF 12.1.x I also used several version of Jasper Reports. There is a whole lot of documentation, blogposts and presentations available. So when today I got a request from one of my customers to make a setup for
In the previous 3 posts, building towards the eProseed IoT Hackathon, I described how to setup your Raspberry Pi, and how to use the GrovePi sensors. The used example is a small weather-station that read temperature and humidity and shows the readings on a display. That is all very nice, however, the data remains local on the Raspberry Pi so there is nothing that we can do with this information
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.
In my previous post I showed you how to setup a simple weather-station using Raspberry Pi, GroovyPi sensors and Python. It worked very well, but there is definitely room for improvement. In this short post I describe some of these improvements. First you will learn how to start the weather-station when you reboot the Pi. Next I will show you how to create some decent log info. Autostart The
Last week I visited ODTUG KScope15 in Hollywood Florida. In this post I will share my findings and hope that you can benefit from it. My general impression of the conference is that it was to hot for me in Florida. At least to hot for a conference. If you can sit on the beach whole day long, it is a great place to be, but hey, I had to work.... From a content perspective, (more...)
This post gives you an Overview of Grove Pi sensors and the fun things that you can do with it. I will add the real content later, but for now we need a placeholder.
This post describes how you can setup your Raspberry Pi in order to start working with it. I will add the real content later, but for now we need a placeholder.
Sunday symposium took of at 8:30. Unfortunately i had to skip the first two session due to some work That had to be done first. The first session I really got to attend was Brian Fry's session on Oracles Developer Cloud Service. JDeveloper, Eclipse or Netbeans was the way you would work with Oracle Developer Cloud. Now there is a new feature (not publicly available) that is a browser based IDE.
Yesterday ODTUG organised the ODTUG Mobile Day in Utrecht the Netherlands. The event was supported by two local user groups, OGh and OBUG, and sponsored by eProseed NL. This full-day event was dedicated to Oracle's next-generation mobile development, infrastructure, and security solutions: "Going Mobile? Where is Oracle Taking You?". All of this was presented by the world’s leading ACE Directors
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
During the closing keynote at the Oracle Fusion Middleware Forum XX in Budapest my former colleague Lucas Jellema and I delivered a live development demo. It was great fun to do. During this demo I developed an Oracle MAF frontend on top of Oracle SOA Suite 12c REST-JSON services. All in all it was a good session that was exactly delivered on-time with no errors. I think the demo gods where with
Mobile apps usually have the possibility to toggle the springboard by using an icon that is displayed in the header of the app. The Oracle MAF reference app, Work Better, also tries to implement this behavior. The showing of the springboard works fine, however, hiding it does not really work as expected. In this post I show you how to implement a working custom toggle springboard functionality.
Images are heavily used in Mobile apps. For instance a list that contains employees usually shows the images of these employees. This works well when you have a WIFI connection, but what if you are using slower connections ? If you look at a mobile twitter app you will see that, depending on connectivity, images are loaded instantaneously or delayed. In this post I explain how you can load the
Two weeks ago I visited Oracle Open World in San Francisco. A glimpse of my activity during Oracle Open World can be found in this post. If you want to hear more, please visit the AMIS Oracle Open World Review Session at October 16th. Saturday After a one hour delay at Amsterdam Schiphol Airport the airplane with, amongst others, several AMIS employees took of for San Francisco. There we met
It has been a while since my previous post, and I have a very good reason for that. I have been busy, very busy. But now, after a long time of writing and rewriting I can finally announce that my book, Oracle Mobile Application Framework Developer Guide, is available for you to buy. Many thanks to my reviewers Chris Muir, Frank Nimphius and Joe Huang who guided and helped me all the way.
Next week the ODTUG KScope conference kicks of in New Orleans. During this conference I will present 3 sessions: June 24th: Goodbye Nightmare: Tips and Tricks for Creating Complex Layouts with Oracle ADF Faces June 25th: ADF Mobile: Best Practices for Developing Applications with Oracle ADF Mobile June 26th: Don't (more...)
Today Oracle published the first in a series of online eLearning training materials. The ADF Academy presents free and online : Developing Applications with ADF Mobile. The main goal is to deliver technical training material to everybody that needs it. You get an online training, where you can view audio (more...)
One very common pattern in Mobile Apps is the use of "pull" to refresh a list of data in an App. For one of my projects I suggested to use this pattern and I had to figure out a way to implement this in ADF Mobile. In this post I (more...)
During the AMIS ADF Masterclass I showed how to take a picture from within an ADF Mobile application, attach it to an Email and send that email out to several recipients. To top it of, I even added the GPS coordinates to the subject, so you know where the picture (more...)
