ADF 12c : Using Jasper Reports en JasperSoft Studio 6.1; What Libraries do you need?

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 the implementation of Jasper Reports 6.1 in ADF 12.1.3 I did not expect any problems. Boy was I wrong. Here is the Story With all the knowledge from the past, I decided to follow the known steps. 1) Download iReport Designer, 2) Build a report in iReport 3) Create an ADF application 4) Add the necessary libraries to use the report 5) Call the report from a button via a Managed Bean Step 1 In the past I used iReport designer to build the reports. When you go to the download site of iReport designer you now see an interesting message. So I took this serious and decided not to u

IoT Hackathon Part IV : Using Web Services to send Sensordata

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 from an 'enterprise' perspective. In this post I will explain how easy it is to send the data to whatever 'end point' by using a REST-JSON web-service. The Database Tables For this use case I decided I needed 2 tables. One to hold all my available sensors (yes, I know, I have only one) and one to store the measurements per sensor. The Webservice In order to store the data in the database tables I need to send it from the Raspberry Pi to the database. For that I use a simple REST/JSON webservice that has a POST method. I also implemented PUT, GET and DELETE methods, becaus
