Quick tip: test HTML pages on a local webserver with NodeJS  

By Frank van der Linden | 5/14/18, 3:10 AM | - | Added by John Oldenburger

At a customer we are building lots of microservices with Spring boot which runs on Pivotal Cloud Foundry hosted at the Azure platform. Some of these microservices are called from web pages with certain specific information, like field info. So in our projects we have most of the time a test html page to mimic the actual behavior.

Quick tip: run your Cloudant data everywhere with CouchDb  

By Frank van der Linden | 5/10/18, 11:31 AM | - | Added by John Oldenburger

I moved our HR Assistant application to a Spring boot to run everywhere, but the data was still stored in a Cloudant database running on IBM Cloud. No problem, but not that flexible. So I was looking for a way to to store the data somewhere with minimum impact.

I got an idea to provide a Cloudant REST API, with the same endpoints of the Domino API but storing everything in Cloudant or CoucheDb. Which results in a Spring Boot application. All the endpoints of the Domino REST API are available in this new REST API.

XPages tip: Multi language support for labels  

By Frank van der Linden | 3/5/16, 9:28 AM | - | Added by Oliver Busse

In 2014 I wrote a blog about controlling the labels in a XPages application, via a web interface, backed by a property file which is inside the application. One of the most wanted requests was multi language support. So I added configurable multi language support to my applications. I used it at several projects with success.

XPages quicktip: use the Calendar build in Months  

By Frank van der Linden | 11/26/15, 4:39 AM | - | Added by John Oldenburger

For a XPages application there was the need to set a Date to a certain date in Java, off course. For this I always use the java.util.Calendar class, because it have some nice extra features. The start is pretty straight forward, get an instance of the Calendar. Next is set the Calendar to a certain time.

Jackson JSON wrapper plugin  

By Frank van der Linden | 10/6/15, 9:00 AM | - | Added by John Oldenburger

A while ago I wrote a OSGi plugin to make the excellent Jackson JSON library available for every application on a Domino server. It works fine, except the security issue. Today I was reading the blog post of John Dalsgaard about ‘Elevating permissions on your third party jar‘. This inspired me to rewrite my Jackson JSON OSGi plugin.

Quick XPages tip: add Fullcalendar plugin to your application  

By Frank van der Linden | 8/27/15, 4:21 AM | - | Added by John Oldenburger

In one of my XPages projects there was the need of a calendar display of data. First stop was the Demo application of the OpenNTF Extension Library, which contains a calendar control. After some attempts to get my data displayed in this control, I skipped it and moved to a JQuery plugin, FullCalendar.
