Embedded Experiences demo - you want to see this!

Mon, 12 Mar 2012 18:51:45 GMT

As I wrote in my Lotusphere 2012 one-liners post after Lotusphere OpenSocial and Embedded Experiences is *the* technology to watch coming out of IBM Lotus. At Lotusphere 2012 Ryan Baxter and Stanton Sievers from IBM gave a Show'n'tell session (SHOW115) which I think really should be an eye opener to a lot of people as to why this embedded experiences "thing" is important. I've been bashing Ryan to make a recording of the session and it's finally here.

Diagnosing wierd widget installation issue

Sat, 18 Feb 2012 20:57:39 GMT

I had a customer report a widget (plugin) installation issue to me. They had clients being unable to install a widget (and hence a plugin) from an update site on our servers (external to their network). The error was reported as below:

Unable to access "http://<host>/site.xml". 
Contains: Error parsing site stream. [White spaces are 
   required between publicId and systemId.]

The issue turned out to be caused by a firewall issue and hence wrongly reported in the log. The issue was solved by relocating the update site to the customers network.

Avoid contacts from mail file gets archived by server-side archiving

Wed, 14 Dec 2011 12:21:37 GMT

Open Mail File template in Domino Designer.
Open "Contact" Form.
Create a new field in this form.
Name it as "ProtectFromArchive"
Field Type should be "NUMBER" with setting "Computed When Composed"
Now set default Value of this field to be "1"
Save the form.

Now The mail database created using this template wont be facing any issue of archiving the contacts documents as field "ProtectFromArchive" will prevent contact docs to get archived. Please note that an agent needs to process existing contacts to protect them as well.

IBM Lotus Domino 8.5.3 server performance and IBM Lotus Notes 8.5.3 client performance

Fri, 09 Dec 2011 07:31:13 GMT

Saw this very nice - although very technincal - whitepaper on developerWorks on how Notes 8.5.3 has been optimized to reduce the number of transactions with the Domino server. A small little thing that I haven't seen mentioned before but which can have a big impact on your environment and users. Probably shouldn't be considered light reading.

"IBM Lotus® Domino® 8.5.3 and IBM Lotus Notes 8.5.3 have been optimized to reduce the transactions from the client to the server. These optimizations yield a reduction in server resources, thus lowering the Total Cost of Ownership. This white paper shows the reductions in processor and disk utilization achieved with large numbers of Notes 8.5.3 clients running on a single Domino 8.5.3 server."

Tip of the day - my Copy Link Location plugin

Mon, 19 Sep 2011 12:36:29 GMT

There are some questions I get asked a lot by customers, colleagues and people I meet at conferences. One of them is why there isn't an easy way to copy links detected in Notes documents using LiveText to the clipboard. And I must admit that it is odd. To remedy I've actually developed a plugin that installs into Notes 8 to add an action item to links in Notes documents. After installing the plugin an action to the Copy Link Location to the clipboard is added to all links in the Notes client.

The plugin really highlights the power of Notes, LiveText and the plugin architecture in Notes. As you will probably recall - plugins are fun!!!

Besides that a right-click context menu is also added when right-clicking Notes documents to copy the Notes link (notes://) to the clipboard. It's all part of the same package.

To see how to install etc. head over to my Notes 8 Utils page.

AbcWidget is trying to be downgraded to a lower installation scope. Reinstallation of this item will not be permitted.

Fri, 24 Jun 2011 06:45:53 GMT

When trying to update a plugin (feature) using a widget the installation failed and I got the below message.

<widget name> is trying to be downgraded to a lower installation 
scope. Reinstallation of this item will not be permitted.

I wondered what it meant as I didn't really understabd the "installation scope" thing so I asked IBM and here's the answer I got from Doug MacDonald. Very useful and nicely explains why the installation failed.

When you install a widget, it is assign a scope. The scopes have a heirarchy.

If the widget was installed from the corporate catalog using a category of widgets, the scope is catalog.push.

If the widget was installed from the corporate catalog using drag and drop, the scope is user.catalog.

If the widget was installed from a location other than the corporate catalog, the scope is user.import.

You cannot move down the scope hierarchy. For example:

Not allowed: If you install a widget from the corporate catalog using a category of widgets and then you try to drag and drop the same widget.

Not allowed: If you install a widget from the corporate catalog using drag and drop and then you try to drag and drop the same widget from a file on the file system.

You can move up in scope. For example:

Allowed: If you install a widget from the corporate catalog using drag and drop and then you install the same widget from the corporate catalog using a category of widgets.

Allowed: If you install a widget by drag and drop from the file system and then install the same widget from the corporate catalog using drag and drop.

jWidgets to make it easier to develop Eclipse based components for composite applications

Fri, 10 Dec 2010 13:24:27 GMT

Perusing the the Composite Application Wiki I discovered a technology IBM calls jWidgets. Basically they are for Composite Application Java component development what iWidgets are to websites that is a widget framework for easily and more quickly doing stuff. Developing Java components for composite applications is a little hard as you have to manage wires etc. yourself. A framework would make that a lot easier and that's exactly what jWidgets are.

Having the technology available to Lotus Notes (and not just Lotus Expeditor) would be really cool. From an IBM'er I however learned that they haven't been formally tested in Notes, but the technical capability is there. They have only been tested formally in Lotus Expeditor 6.2.2.
