Adding Notes data to Websphere content manager via RSS
Mon, Jul 27th 2015 9:24a   Stephan H Wissel
Websphere Content Manager (WCM) can aggregate information from various sources in many formats. A quick and dirty way to add Domino data is to use RSS. The simplest way is to add a page (not an XPage, a Page), define its content type as application/rss+xml and add a few lines to it: feed.xml Extraction of data from the Audience Governance database [Embedded view here] Thereafter create a view with passthrou HTML with all the values for an item element. Of course tha

Midget Imaginaire - Scheinzwerg
Wed, Jul 15th 2015 1:35p   Stephan H Wissel
The imaginary midget This is an attempt to transpose a concept deeply rooted in the German cultural context into another language. Bear with me. Over at Omnisophie Professor Dueck has a column titled "Scheinzwerge" (loosely translated: imaginative dwarfs|midgets|gnomes), dealing, besides others, with the Greek crisis. It draws heavily on a very German childhood classic "Jim Button and Luke the Engine Driver". In this famous children book and string puppet play we meet Mr. Tur Tur who is a

Validating JSON object
Sat, Jul 11th 2015 1:45p   Stephan H Wissel
One of the nice tools for rapid application development in Bluemix is Node-RED which escapted from IBM research. One passes a msg JSON object between nodes that process (mostly) the msg.payload property. A feature I like a lot is the ability to use a http input node that can listen to a POST on an URL and automatically translates the posted form into a JSON object. The conversion runs non-discriminatory, so any field that is added to the form will end up in the JSON object. In a real world app

Random insights in Bluemix development (a.k.a Die Leiden des Jungen W)
Mon, Jun 29th 2015 5:31a   Stephan H Wissel
Each platform comes with it's own little challenges, things that work differently than you expect. Those little things can easily steal a few hours. This post collects some of my random insights: Development cycle I'm a big fan of offline development. My preferred way is to use a local git repository and push my code to Bluemix DevOps service to handle compilation and deployment. It comes with a few caveats When you do anything beyond basic Java, you want to use Apache Maven. The dependency

Investigating JNDI
Thu, Jun 18th 2015 5:18a   Stephan H Wissel
When developing Java, locally or for Bluemix a best practise is to use JNDI to access resources and services you use. In Cloud Foundry all services are listed in the VCAP_SERVICES environment variable and could be parsed as JSON string. However this would make the application platform dependent, which is something you want to avoid. Typically a JNDI service requires to edit the server.xml to point to the right service. However editing the server.xml in Bluemix is something you do want to avoid

Adventures with NodeRed
Tue, Jun 2nd 2015 10:42a   Stephan H Wissel
Node-RED is a project that succesfully escaped "ET" - not the alien but IBM's Emerging Technology group. Build on top of node.js, Node-RED runs in many places, including the Rasberry PI and IBM Bluemix. In Node-RED the flow between nodes is graphically represented by lines you drag between them, requiring just a little scripting to get them going. The interesting part are the nodes that are available (unless you fancy to write your own): A large array of ready made flows with nodes and samp

Your API needs a plan (a.k.a. API Management)
Tue, May 19th 2015 9:12p   Stephan H Wissel
You drank the API Economy cool aid and created some neat https addressable calls using Restify or JAX-RS. Digging deeper into the concept of micro services you realize, a https callable endpoint doesn't make it an API. There are a few more steps involved. O'Reilly provides a nice summary in the book Building Microservices, so you might want to add that to your reading list. In a nutshell: You need to document your APIs. The most popular tool here seems to be Swagger and WSDL 2.0 (I also lik

The Rise of JavaScript and Docker
Sat, May 9th 2015 2:25a   Stephan H Wissel
I loosely used JavaScript in this headline to refers to a set of technologies: node.js, Meteor, Angular.js ( or React.js). They share a communality with Docker that explains their (pun intended) meteoric rise. Lets take a step back: JavaScript on the server isn't exactly new. The first server side JavaScript was implemented 1998 and the Union mount, that made Docker possible, is from 1990 too. Client side JavaScript frameworks are plenty too. So what made the mentioned ones so successful? I

Cloud with a chance of TAR balls (or: what is your exit strategy)
Sun, Apr 12th 2015 7:15a   Stephan H Wissel
Cloud computing is here to stay, since it does have many benefits. However even unions made "until death do us part" come with wagers these days. So it is prudent for your cloud strategy to contemplate an exit strategy. Such a strategy depends on the flavour of cloud you have chosen (IaaS, PaaS, SaaS, BaaS) and might require to adjust the way you on-board in the first place. Let me shed some light on the options: IaaS When renting virtual machines from a book seller, a complete box from class

email Dashboard for the rest of us - Part 2

In Part 1 I introduced a potential set of Java interfaces for the dashboard. In this installment I'll have a look on how to extract this data from a mail database. There are several considerations to be taken into account: The source needs to supply data only from a defined range of dates - I will use 14 as an example The type of entries needed are: eMails replies Calendar entries Followups I'm waiting for Followups I need to action Data needs to be in details and in summary (counts) People
