Custom widgets for IBM Connections v.5.5 and what the "themes" attribute mean
Tue, Jan 26th 2016 8:27a   Mikkel Heisterberg
Starting with IBM Connections v. 5.5 a new required attribute was added to the widgets-config.xml file that controls how widgets are rendered for Profiles and Communities. IBM addresses the issue by referring to a technote (Custom widgets not displaying correctly after migrating to IBM Connections 5.5) that mentions just adding an attribute. The fact that simply requiring customers to add static text is lunacy for a product - if you need something where a static text will do for most cases and i

If only IBM had a mail client...
Wed, Jan 6th 2016 2:57p   Mikkel Heisterberg
Over the last year we've seen more and more customers move to Microsoft Office 365 for mail and calendaring. The funny thing is that very few users actually end up using the webmail experience but almost all end up in Outlook. This made me think that IBM could probably still be competitive in the mail market including for the people who prefer a rich client if it wasn't for IBM Notes. The client is simply too bloated, too slow and too difficult to centrally manage and update. Oh and then there

Introduction to OAuth - the technology you need but never really learned
Thu, Nov 5th 2015 4:11a   Mikkel Heisterberg
OAuth is core to integrations these days but I see many developers that try and use OAuth without really understanding the protocol. The protocol is very easy to understand so I created this presentation to try and explain it in easy, visual, chunks. I'll present on the topic tomorrow (Friday 6 November 2015) at the Social Connections IX conference in Stuttgart, Germany. I hope you'll come see it live if you are at the conference.

Possible to crash WAS using System.out.println?
Wed, Sep 30th 2015 8:34a   Mikkel Heisterberg
I've been pulling my hair out trying to diagnose an issue we've been having with the OnTime Group Calendar Social components that is the widgets we have for IBM Connections. After loads of frustration and lost time I've managed to find the issue and will document it here for the future and for Google. The issue which appears on WebSphere Application Server ND v. 8.5.5.3 and 8.5.5.4 is caused by doing a simple System.out.println. This makes the server go bananas, throw a NullPointerExceptio

PaaS, Bluemix and controlling runtime costs with cron
Mon, Sep 21st 2015 3:14a   Mikkel Heisterberg
Back at IBM ConnectED 2015 I created a small demo for IBM using the yet-to-be-released extensibility API of IBM Verse to show of third party extension of IBM Verse. Ever since IBM has been using the demo which is great. The app I wrote is running on Bluemix and I turn it on and off whenever they need it. Now with Bluemix being a Platform As A Service (PaaS) offering I pay for the resource I use and since IBM is still to own up and provider partners with a free plan or larger allowance the monthl

Getting ready for iOS 9 and App Transport Security (ATS)
Tue, Sep 1st 2015 6:08a   Mikkel Heisterberg
Much has already been written on the web about the upcoming iOS 9 release and how Apple is tightening security with App Transport Security (ATS) which basically only allows for HTTPS traffic using advanced and secure ciphers. Other voices in the community is staying on top and blogging much more about it and how it pertains to IBM Traveler and particularly if you are terminating your IBM Traveler connections on Domino. As it stands now (IBM Domino 9.0.1 FP4) IBM Domino cannot deliver the ciphers

IBM Connections Cloud (SmartCloud) FINALLY adds much awaited feature
Wed, Aug 26th 2015 2:55a   Mikkel Heisterberg
We have had OnTime Group Calendar working with IBM Connections Cloud (SmartCloud) for a years so that customers could move all or part of their mail users to IBM Connections Cloud and host OnTime Group Calendar on-premises or (IBM SmartCloud Notes Hybrid). We have seen adoption and do have customers using it but the main obstacle to full adoption by customers has been the lack of mailfile ACL controls for the customers. Since we require access to the mail files (we do need to read data you know.

Eclipse target platform invalidated by IBM Notes 9.0.1FP4 on Mac
Mon, Jul 20th 2015 3:04a   Mikkel Heisterberg
After installing IBM Notes 9.0.1FP4 I have been unable to launch Notes from my Eclipse workspace when doing RCP development (i.e. plugin development) for Notes. I finally decided to solve it. The stacktrace is like the one below: 2015/07/20 08:16:42.280 SEVERE CLPDN0016E: Error starting RCPApplication com.ibm.rcp.personality.framework.RCPApplication ::class.method=com.ibm.rcp.personality.framework.internal.RCPApplication.run() ::thread=Thread-1 ::loggername=com.ibm.rcp.personality.framework.i

IBM Notes IBM Connections plugins cannot connect after upgrade to v. 9.0.1FP4 on Mac

After upgrading to IBM Notes 9.0.1 on my Mac the IBM Connections activities sidebar plugin failed to connect to our IBM Connections server. After tingering around with connection settings I checked the trace log and saw the below stacktrace: CWPST0306W: An exception occurred while invoking the target method login. javax.security.auth.login.LoginException at com.ibm.rcp.accounts.internal.auth.module.AbstractJ2eeFormLoginModule.login(AbstractJ2eeFormLoginModule.java:393) at sun.reflect.NativeMe

Guest post - Moving on: Brian O'Neill Edition
Mon, Mar 30th 2015 5:33p   Mikkel Heisterberg
First, thanks to Mikkel for letting me publish this on his blog. I've always gone back and forth about starting my own blog in the past, but never did, hence why I needed some help to get this message out. So, why am I writing? I'm excited to announce that I have accepted a new role within my current company, Gore. I will be transitioning into our customer facing capabilities center in Newark, Delaware. I will be championing the digital experience in that facility as well as helping the exis

Have VMWare ESXi VM hardware look like the underlying hardware
Mon, Mar 30th 2015 5:28p   Mikkel Heisterberg
Had an issue today where I couldn't use the IBM OEM Windows 2012R2 media that IBM provided together with our new xServer because the media running in the ESXi VM didn't see the underlying IBM hardware. The solution was to set an ESXi option on the VM called SMBIOS.reflectHost = "TRUE" as described in this post (Unable to install Microsoft Windows Server 2012 on VMware ESXi host - IBM System x). That made the VM represent the underlying hardware.

git log to the rescue
Tue, Mar 17th 2015 8:46a   Mikkel Heisterberg
Today I needed to figure out when a certain setting (DisablePrint - funnily enough disables print in the OnTime Group Calendar Notes UI's) was added to OnTime Group Calendar and I just couldn't remember. So how would I find out? No way was I going to do diffs all the way back through all my tags. A bit of googling and voila! - git log to the rescue. Using a combination of git log and git tag I was able to find out in a couple of minutes. Besides being very cool and an excellent display of the

IBM announce dates for bringing TLS v. 1.2 to IBM Domino
Mon, Mar 16th 2015 3:02a   Mikkel Heisterberg
So in October of 2014 I wrote about the upcoming TLS (transport layer security) enhancements that IBM was planning to bring to IBM Domino as part of the industry wide panic about the POODLE attack which I still consider mainly theoretical. I was a bit critical towards IBM as they chose to patch their seriously lacking SSL v. 1.3 implementation and implement TLS v. 1.0 on top of IBM Domino v. 9.0.x (IBM Domino, POODLE, SHA-1 and why it's also sad when IBM decides to update the security stack).

Docker without sudo
Sat, Mar 14th 2015 3:14p   Mikkel Heisterberg
Using Docker looks very promising but having to use sudo all the time is really a killer. Luckily there's a way around it by adding users to the docker group and restarting the docker service. Add the docker group if it doesn't already exist: sudo groupadd docker Add the connected user "${USER}" to the docker group. Change the user name to match your preferred user: sudo gpasswd -a ${USER} docker Restart the Docker daemon: sudo service docker restart If you are on Ubuntu 14.04 and up use do

Nice way to export from DB2 command line

Stumbled on this very nice easy way to export to a delimited file from the DB2 Command Line Prompt (CLI) today. db2 "EXPORT TO OF DEL MODIFIED BY NOCHARDEL " i.e. db2 "EXPORT TO result.csv OF DEL MODIFIED BY NOCHARDEL select * from empinst.employee"

Hiding widget on my own profile
Thu, Feb 12th 2015 4:27p   Mikkel Heisterberg
Was looking through widgets-config.xml for IBM Connections v.5 to diagnose a customer issue and stumbled on the below widgetDef attribute. Now I haven't tried it yet but it looks like you can use it to hide a certain widget on your own profile e.g. only show when viewing other peoples profile. Could be useful. hideWidgetForMyProfile="true"
