At Dannotes today

Today I’m at the Danish Notes User Group (Dannotes) in Korsør here in Denmark. This time there is a very interesting lineup for this two day event as Gabriella Davis from the Tutle Partnership is here to present on admin stuff and Andre Guirard from IBM is here to present on the new an exiting stuff for appdev. I actually just had a nice chat with Andre which was nice.

I’m doing, what I hope will be, an inspirational session on what’s possible in the Notes 8 client using widgets and some nice plug-ins. Should be fun.

Configuring SSO between Lotus Domino and Lotus Connections

This morning I configured single-sign-on (SSO) between Lotus Connections and Lotus Domino and was again surprised by how easy it is. The steps are simple:

  1. Open the WAS server administration interface and go to Security > Secure administration, applications, and infrastructure > Authentication mechanisms and expiration.
  2. Select “Authentication mechanisms and expiration” in the “Authentication” section on the right hand side.
  3. Now in the “Cross-cell single sign-on” section specify a set of passwords and export the keys to a file on the file system.
  4. Move the file to your local file system.
  5. Now follow the guidelines in the Domino Administrator help for importing the keys into Domino LTPA configuration.

Lotus Connections teaches you how to scale images in Java

Lotus Connections is a little bit screwy when it comes to profile pictures IMHO as they are being forced to be square in Profiles (115×115 pixels). In profiles search results however they are scaled to 55 pixel in width and height is automatic…

In my mind portrait pictures are rectangular and not square.

Yesterday this gave me some grief as I was at a customer where I had to write Java code to import pictures in the PHOTO table of the Lotus Connections PEOPLEDB database. The actual importing the pictures into the database is easy using JDBC but the pictures showed up wrongly in Lotus Connections as they were rectangular (200 x 133 pixels). They clearly had to be scaled but how – clearly not manually!

As with many other things you are gifted with Java as it already contains all the pieces you need to scale pictures. I quickly found some sample code on Google to use java.awt for the resizing. The solution was to

  1. Scale the source image from 200 x 133 pixels to 115 x 76 pixels to keep the aspect ratio
  2. Create a new blank white image sized 115 x 115 pixels
  3. Place the resized source image on top of the white image centered
  4. Upload the resulting image to the database as a byte array

Love Java!
