Property Converter 2 Component

I had a meeting with a customer last week and introduced the Property Converter component to them and it quickly became a design discussion.  The result was, I took the OpenNTF project and implemented these changes.  The result is a new hidden component that can have N number of properties defined and you can attach a script (JavaScript) to each of those properties to do transformations or string manipulations.  The other modification is both the new and the old component now stores the scripts in the component data (which now transports with the composite application).  This should greatly reduce the amount of Java code and custom actions many people do to manipulate strings (properties).  This also means any time you need a new transformation you simply create a new property.

Once I get the legal approvals I will be submitting this back to OpenNTF.

New features:


  • Now saves the script with the component.
  • Now uses the new API’s for tooling in the CAE
  • The Save button and text field is hidden/readonly in the runtime
  • Test button now publishes the value to the property broker.
  • Added it to the CAE palette under “OpenNTF” category

PropertyConvert2 – brand new component

  • Based on the original concept but allows N number of properties to be created.
  • Each property is associated with its own script.
  • All scripts and properties are stored with the component in the CA.xml
  • The test button publishes the property.
  • Added it to the CAE palette under “OpenNTF” category

Here is a sample of the components in the run time (can be Notes or Expeditor) – realistically these would be hidden so they would be more like service level components.  The red lines show the flow of the wiring and I used a basic web browser component to display the resulting text.  You can imagine these components are hidden and you would only have your normal application components visible and these components doing the transformation.

Components in the CAE:

Notice the Save buttons and the script is now enabled for editing.  The component “knows” when it is in edit mode and allows the assembler to modify scripts and add properties.

Poll: Do you want education material on creating Java views showing Notes data?

I got a lot of random emails on this subject ever since BONES was put on the blogosphere but I would like to get a better picture of the demand. This refers to SWT and JFace views, not the built in Java rendering that will be possible in Notes 8.5.1.

Why you don’t have to suck at Eclipse plugins…

My friend and former colleague Juan R. Rodriguez from Everclear Technologies Inc. is offering a 4 day workshop on developing plugins and composite applications for Expeditor 6.2 – which is what Lotus Notes 8.5 is based on.  You can check out the agenda and labs below – you will get a very wide breath of coverage in the Eclipse and Expeditor platform with the principles of componentation and composites applied.  So if you want to impress Nathan or get hired by his team you might want to check out this workshop.

Workshop agenda

  • Workshop Overview
  • Composite Applications
  • OSGi Overview and Architecture
  • Eclipse architecture and the plug-in model, fragments and features, IDE and wizards

  • Lab 1 – Hello World and building a composite application
  • Lab 2 – Develop eclipse components using Eclipse IDE
  • Lab 3 – Component collaboration with Property Broker
  • Lab 4 – Creating Fragments

Expeditor’s most wanted!

The Lotus Expeditor Wiki is asking for input on anything and everything Expeditor.  The platform under Lotus Notes, Sametime, and Symphony is a very powerful platform based on Eclipse.  If you want to see more education material or postings on API’s, plugins, patterns, or anything related to the Eclipse side of the Lotus products, post your needs here.

Will HTML 5 kill Flash and Silverlight?

Very interesting article over at the InfoWorld site.  It has a lot of valid points and I think if something so standard as “HTML” will provide this stuff then it makes me understand why Microsoft is so reluctant to support HTML 5.

“HTML 5, a groundbreaking upgrade to the prominent Web presentation specification, could become a game-changer in Web application development, one that might even make obsolete such plug-in-based rich Internet application (RIA) technologies as Adobe Flash, Microsoft Silverlight, and Sun JavaFX.” – link

Extending Lotus Symphony

Many probably know that Lotus Symphony is based on Lotus Expeditor and Eclipse but you may not have put two and two together for new opportunities.  You can install pretty much any Eclipse plugin into stand alone Symphony; by default the Eclipse plugin install menu is enabled:


Now, in Symphony 1.3, there is also support for composite applications.  So if a Notes or Expeditor developer create a .CA file a Lotus Symphony user can open it.  Of course you will have to make sure any features developed for are linked in the .CA file so it can be launched correctly.


So from a business partner point you can provide plugins and composite applications for the Symphony product suite.  You can also deploy entire RCP based applications to Symphony.  If you have the coolest plugin you can essentially deploy it to Symphony, Notes, Sametime, and Expeditor installations.

Online Eclipse RCP Training

I was checking my blog this morning for comments and I noticed this Google Ad for Quickstart Eclipse RCP Training so I clicked the link and found a pretty nice venue for Eclipse RCP education.  I often recommend the old RCP book (which is kind of dated at this point) and I think getting a fresh online course is much better considering most of what you can find is on the internet.  Once you get a primer with the basics you will be able to Google for just about anything.  This course looks like it starts in about 2 weeks.

From the site:

Public RCP Quickstart course to be held online, June 24th – 26th, 2009.


This course will be held online using the GoToMeeting service. The PDF manual and lab materials will be delivered as an encrypted archive available a few days before the course begins.
The timing of the course is meant to be convenient for students throughout North America, though you’re welcome to take the course from anywhere in the world. The specific course times for the North American time zones are as follows:

  • Eastern: 11am – 6pm
  • Central: 10am – 5pm
  • Mountain: 9am – 4pm
  • Pacific: 8am – 3pm
