Websphere Liberty Profile and external authentication redirect

At one of my customers I was busy with the upgrade their virtual development environment.

Current state

Currently we run Websphere Application Sever 8 inside Rational Application Developer on a not so fat virtual development environment. Which cause lots of waiting for the developer to deploy changes of the portal to the local WAS server.

We tried JRebel, but in combination with RAD I can say it is not happy couple. It caused have memory use and after a certain period a not response environment ;-(


New environment and a problem

So we decided to move for the development environment to the latest Eclipse version with Websphere Liberty Profile.

Benefit of Eclipse is a more lean IDE, where we can install SonarLint and Findbugs plugins. WLP for local development is also much more easier to install and much faster.

After I ran the migration tooling in Eclipse I had my server.xml, so that was easy šŸ˜‰

To run theĀ EAR files of our portals should be untouched, because on production we still use WAS.

The portals run also on JSF 1.2, so we load the JSF and the properties via commonLibrary on the class path.


Voila, one of the portals was running on WLP, which is using Basic Authentication, but……. the others using an external Ā authentication mechanisme. After successful authentication the user is redirected back to the portal.

This redirect caused a connection refused error ;-(


The solution

On the website of IBM I found the solution.

By adding host=”*” to the httpEndpoint tag, which tells WLP to accept all incoming requests.

The final httpEndpoint looks like this

<httpEndpoint id="defaultHttpEndpoint" host="*" httpPort="8081" httpsPort="443" />

Happy coding

My slides of my Cloudant introduction session at Meet IT

Last Wednesday Meet IT conference was held at IBM Client Center in Milan. I did a session about Cloudant and how you can use it inside an XPages application.

My session was in the Auditorium, a big room like a theater with good chairs, very good audio and screens. Was nice to it such big room.


A big thanks to Giuseppe Grasso, Daniele Grillo and Stefano Benassi for organising it. All well deserved IBM Champions

I am an IBM Champion, again


Yesterday at MeetIT conferenceĀ in Milan, Amanda Bauman, has announced the IBM Champions for ICS.

I am among the 123 IBM Champions in 2017, and that makes me very happy.

It is the third time after 2013 and 2014, but the first time as an Freelancer.


Thanks to all how nominated me.

Let see what 2017 will bring as an IBM Champion. One great event is already known, speaking at IBM InterConnect.


A special attention for 2 new Dutch IBM Champions, Ronald Dekkers from Acuity and Remco Angioni, my former colleague at e-office.

My abstract has been accepted for IBM InterConnect 2017


Yesterday I received an email from the IBM InterConnect 2017 team with the message that my abstract has been accepted.

Wow, was stunned, and happy and a little bit ‘scared’……..

When the news is setting in, I was thinking of the next steps.

I already made the registration, next housing and flights. And of course preparing my slide deck

My session will be about our HR Assistant application we build for the ICS Development Competition, with a deep dive in the code and lessons learned.


Hope to see you in Las Vegas…..

Special page for my open source projects

Tonight I thought it would be a good idea to create a special page at my side with links of all my open source projects.

You can find them hereĀ or at the bottom of my homepage.

My evolution as a developer: becoming a Full stack developer

evolution of a developer

Is the time of the year to have some time to reflect.


Entering the IT

Around 2000 I entered the IT world, first as a Domino Administrator, but after a good talk with a former colleague I made the switch to become a Developer.

So I became Domino Developer and learned Formula language and later Lotusscript. Did some certifications.

When the browser became more important I moved more and more to web development and did some great projects, for example I build the public website of a big insurance company. Was a lot of fun and challenges on such a high traffic website.


Learning Java

Along with these web development projects there was also an increasing amount of Java projects, so I learned Java and did a few nice Java projects. It was really nice to do these Java backend projects, but Front end development was Ā  screaming for my attention



In 2008 IBM introduced XPages, and implementation of JSF. They took 1.1 version and ripped out all the unnecessary parts and added much needed features, which are still not native in the latest greatest version of JSF, like partial refresh. Which the XPages developer took for granted.

I was an early adapter, and despite of the lack of Documentation I liked it. At that time, It was a perfect combination, Java in de the back end, combined with Front end development, like HTML, JS and CSS.

I have build nice solutions.


Going freelance

In 2014 I made the decision to start my own business and became a freelance developer. As a freelancer I followed the money and in the Netherlands there is high demand of Java developer, especially in the enterprise world. So I moved more and more to the JEE world, learned a lot of new tooling, like Maven, Jenkins, JUnit testing and much more…

Most of the applications I build was based on JSF, with a lot of Spring Framework.

Meanwhile there was also time to build more XPages based applications, like the HR Assistant which was our entry of the ICS Development Competition, where we used Cloudant as datastore and IBM Watson to analyse.

I also found some time to learn more of the Salesforce platform, I heard good things about it. I must admit I liked the way Salesforce helping to get new Developers on board, via their Trailhead platform


Full stack

The last months I was looking around to new technology, had a short look at ReactJS. Looks good and very lightweight, the developer descide what should be loaded. Created a very small application.

But now AngularJS 2 has been gone gold, I am learning as much as possible. Took our HR Assistant application as an example and I am busy to rebuild it in AngularJS 2. It is a steep learning curve, but I can get the data from Cloudant, so what could go wrong šŸ˜‰


Next step

First of January 2017Ā I will start as full stack Java developer,Ā at a new customer. It will be a very interesting project with lots of new technology like Java, AngularJS, Docker, Salesforce, Websphere Liberty. They are also looking to the cloud, and Bluemix was mentioned.

So interesting times are ahead and I am looking forward to this new step in my career.

HR Assistant now as project at OpenNTF


Today I have added our winning application, HR Assistant, as project at OpenNTF.

I have added the source code in a zip as the release, but I encourage you to go to the Github repository directly.

Included a notice and license file, which is required for every project on OpenNTF.

And last but not least, there are screenshots and….. documentation šŸ˜‰


Have fun with it. And a demo is in the making.

Cloudant connector plugin update: manage Design documents


Yesterday I was helping outĀ Patrick Kwinten with some he had with my Cloudant Connector pluginĀ on Slack. He asked also about the possibility to add or modify Design Documents, I found there foundation was already there.


Design Documents

Design documents can be seen asĀ the schema in your Cloudant database, which specify what is in the view and how the ftSearch index is build.

Below is an example of a Design Document. As everything in Cloudant the syntax is JSON.

Cloudant Design Document


New methods

As I wrote before, the foundation was already laid in the plugin, the only I had to do was to expose them to the outside world. With this new methods you can programmatically create or update Design Documents.

  • connector.getDocumentConnector().createDesignDocument(final Map<String, String> updates, final String designDocument)
  • connector.getDocumentConnector().updateDesignDocument(final Map<String, String> updates, final String designDocument)

updates, map of updates, where the value of the map is the javascript of the selection designDocument:

updates.put("newUpdateHandler", "function (doc, req) { ... }");

the name of the designDocument to create or update



Everything, including an updated ReadMe is in the BitBucket repository.

Thanks to Patrick for the great blogpost with boilerplate, where you can see the plugin in action.

When you need help with the plugin, let me know or reach out to me on Slack as Patrick did.

When you have feature request, please create an issue in the BitBucket Repository and I will have look if it will make it to the plugin.
