I will be speaking at Engage, ship ahoy!

Earlier this week I got the confirmation from Theo Heselmans that my session proposal was accepted.

I am extremely proud to speaking again at Engage. The agenda is, again, top notch.

Engage is always a special place for me, because Theo gave me, in 2012, the opportunity to speak for the first time at such a conference.

My session

On Tuesday May 22 at 17:00 in the Sky Room I will speaking about Spring boot and Thymeleaf.

Dev03. Spring forward: an introduction to Spring boot and Thymeleaf for (XPages) developers

The world of (XPages) developer is moving fast. Customers rethinking platforms and solutions. Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”. In combination with Thymeleaf can it be good alternative for your XPages applications.
In this session I give an introduction of Spring Boot and Thymeleaf and how to get started. I will show the differences and simularities between Spring Boot in combination with Thymeleaf and XPages.
I will explain the challenges I faced when moving an application.


Happy to be back and hope to see you all in Rotterdam.

The next period I need to run more, to be prepared for all the chocolate 😉



Quick tip: Front end frameworks and Maven dependencies

Lately I am only building application with Spring Boot, where I use Thymeleaf front end templating engine.

A very powerful combination, but sometimes you need other Front end frameworks, like Bootstrap or JQuery and more.


You can add all the required files of the desired front end frameworks to the resource directories for your static files, like css and javascript.

I found out is a lot of work to get all these files, but some of these projects has dependencies with other projects. Then it gets messy.


Head over to WebJars, to find your needed frameworks. Select the version and the Build tool and you get the required code to add to your build file. In my case it Maven. So I added the Dependency code to my pom.xml and run a ‘mvn clean install’ and voila all the files are added to my project.


When there is an update of project, just increase the version number and rerun the ‘mvn clean install’ to get up to date.

How to use

The files are not visible under the resource folder. But can used directly in your html files.


What I am thinking about IBM Think

2 weeks ago I have attended IBM Think in Las Vegas. The super conference of IBM by merging all the other conferences, like InterConnect, Edge, Amplify, World Of Watson and Connect/Lotusphere


Overall impression

Last year I was at IBM InterConnect, so I was prepared for the amount of attendees. And yes on Monday when Partnerworld and the Showcase where not running, it was a bit crowded in the hallways. Food was not bad, but the coffee, as an European, was a lacking caffeine 😉

The showcase was huge. The set up with lots of Think Tanks and Theaters was a good approach. A more informal way to deliver content.

As a developer the Dev Zone was a sort of coming home. Had a few good discussions with IBM developers.

Meeting lots of other IBM Champions and the ‘feeling special’ feeling provided by Libby and her wranglers made it worth to attend IBM Think

Domino and the future

The development of Domino and Notes where moved to HCL, and lots of IBM-ers have followed the code. In the past month the Jams and webinars shows a increasing interest to make Domino Great again.

At Think they announced the support of iOS, in other words all the Notes applications will run natively on a iPad.

In my opinion this is good news for the Notes apps, but modernisation of the apps is still needed. Lots of Notes apps do not have the sexy look and feel, so they will not look any better on an iPad.

My worry is the Notes developers. They might be thinking they stay on Lotusscript and @Fomulas forever. I think it is not career proof strategy.

The announcement of NodeJS support of Domino is very good one. Now we can make cutting edge front end / mobile apps with the latest and greatest frontend frameworks, like Angular/React/Vue……


Collaboration sessions

Collaboration solutions has an own morning with very good sessions. Especially the session of Rene Schimmer about IBM Connections was good. Lots of great new features on the horizon and Rene presented it very relaxed in a steady pace.

Almost all the ‘other’ ICS sessions where in room Surf B. Very well planned, so ICS has almost their own room to gather. Smart move.


Handson labs

I did a few hands-on labs, for me the best way to learn. I did one about IoT and Node-Red, one about Blockchain and one about deploy Microservices via Kubernetes.

I must say these where the best things at IBM Think.

Community and Champion day

At Sunday IBM Think started with Community and Champion day. A day full of content about User groups and more. Lots of sessions were presented by my fellow IBM Champions.


Next year IBM Think will be moved to San Francisco to fill the Moscone Center. Mark the date, February 12th till 15th 2019. Hope to see you there

IBM Think: my topics

With IBM Think 2018 just around the corner, it is time to finalise my schedule.

I am fortunately to be already in Las Vegas to run a 12K tomorrow near the Hoover Dam.

There are so many sessions at IBM Think, that it could be overwhelming.

Pick topics

As at IBM InterConnect I picked a few topics of my interest. What do I want know more of

  • Blockchain, not just the theory, but I want to know more what is in it for me as developer
  • Microservices, what are the best practices, share thoughts on microservices
  • Kubernetes, I run already Springboot apps in Docker containers, but I want to learn more about to manage
  • Java, what is the latest and greatest in Java 10.

Of course I will be frequently at the DevZone. The place to be to talk to IBM devs

Session conflicts

With so many concurrent session there is always the problem of session conflicts.

I just plan the sessions I want to attent. Which will cause may be conflicts.

No problem for me, that way I can choose which session I will attend at the moment. More flexible to me.


Hope to see you at IBM Think

Viva Las Vegas

I am speaking at SNoUG, see you in Zurich

End of last week I received an very pleasent email from Andrew Magerman.

My session has been accepted for SNoUG 2018 in Zurich on April 18th.

I will be speaking at EntwicklerCamp, again


I am pleased to return to EntwicklerCamp in Germany. This year it will be April 23rd till April 25th.

My sessions

At EntwicklerCamp I will do an enhanced session about HR Assistant, focused on the development part. I will show the latest enhancements.

In my second session I will give an introduction to Spring Boot and Thymeleaf, focused on XPages developers. Will show the similarities and the differences. And lots of code examples.


Hope to see you end of April in Gelsenkirschen.

Make the NSF modern again with OpenNTF Domino API

Currently the Domino Jam 2025 on  underway, both on premise or online, where you can have a say about the missing features for the next Domino releases.

Go participate today, https://www.ibm.com/developerworks/community/groups/community/domino2025.

One of the idea posted by my fellow IBM Champion Daniele Grillo about moving the NSF to a more modern NoSQL approach. I totally agree with him.

Domino/NSF has some very cool features like security. But also a few but very annoying limitations.

MongoDb and CouchDb (or Cloudant) to mention a few very popular NoSQL datastore has overtaken Domino/NSF. The documents are stored as JSON, which makes it very flexible.

Make it modern with OpenNTF Domino API

For HR Assistant we store everything in a Cloudant datastore running on Bluemix. With a OSGi plugin who do the conversion from Java objects to JSON both ways, we store all the data.

A customer had the requirement to save all the data in a NSF, which was not our preferred way. One plus was they were not using the Notes Client to view the data.

So I was looking around who to do it and I found a solution, thanks to Paul Withers (as always ;-))

OpenNTF Domino API has a build in mechanism to convert a field to RichText if the stored data is too big for a normal field.

That was the solution to store all the JSON data direct in 1 notes field, in a document. Almost the way we store the data in a Cloudant datastore. In the end I created a DominoJSONService class with a few CRUD methods

A small code example which shows I can feed the method every object

DominoJSONService example

I store all the data in ‘json’ field, with Jackson Json Mapper to convert the Java objects to JSON.

For this purpose I also store the dataType, which is used in the selection formula of the view.


This opens up lots of possibilities for the ‘old’ NSF.

Happy coding

IBM Champion 2018

Today when I came back from an early morning ride on the mountain bike there was a message from IBM to inform me that I will be a returning IBM Champion.

Feel honoured to be part of an amazing group of dedicated people.

Thanks to everyone who nominate me and the people at IBM who had the task to choose the new class

Also many thanks to Alan Hamilton, program manager of ICS, but also to Libby Ingrassia, the overall IBM Champion program manager

Hope to meet in Las Vegas during IBM Think more fellow IBM Champions as I did last year at IBM InterConnect.


Look back to 2017 and looking ahead












Last week I was thinking about 2017, business and personal wise. Speaking, running, backpacking, being a IBM Champion and more….

Speaking in 2017

Last year I had the opportunity to speak at IBM Connect in San Francisco, IBM InterConnect in Las Vegas and Engage in Antwerp. I enjoyed it very much. Especially InterConnect was one of the highlights. A real big conference, lots of attendees. Learnt a lot new things from other IBM parts then ICS. Engage, organised by Theo and Hilde ( and team ) is always top notch. I am always happy to be there, as a speaker or attendee.

Projects in 2017

In 2017 I started at Rabobank as a Full Stack Developer in very nice team. We had a lot of fun, but also delivered some nice new features to the business. Technologies we used, Angular4, SpringBoot, Thymeleaf. But also some older technologies.

With Belsoft Collaboration we added some cool new features to the HR Assistant application. Added Document Conversion, but also multi language support. HR Assistant runs now on Domino and Bluemix. Deployed it at customer and made a few custom features for this customer.

Started in December with a former team member a totally new project. Technologies we will use, Spring Boot, Thymeleaf, Spring Security, MyBatis, Lombok, Docker and certainly more new goodies.

Holiday in 2017

During the summer I backpacked with my family through Indonesia, spent time on some bounty islands. Made a stopover in Singapore, which was a nice start and finish of the journey.

Sport in 2017

In did not that many sports in 2017 as wanted to. In the spring I had small knee problems. In the fall my health was not that stable. Fortunately I can commute every day on the bike to Rabobank.

Looking ahead

In 2018 I will attending, may be speaking, IBM Think. The new all-in-one conference in Las Vegas in March. Looking forward to be back in Las Vegas and meet everyone. I also will run the 12K at the St Patricks Day Run.

This week I also submitted an abstract for Engage, this year on the s.s. Rotterdam in Rotterdam. I also found the courage to submit an abstract for Spring IO in Barcelona. About to move an XPages application to Spring Boot. What I learn and the challenges. As I am busy moving HR Assistant as a business case.

In 2018 I will continue to learn more of Spring Boot and all the nice extra’s Pivotal is offering.

It will be an interesting year, and looking forward to learn and share more.
