Uninstalling Java extensions (“plugins”)


Yesterday I tried to install the OpenLog logger plugin in my development environment (Notes 9.0.x) to add some more common logging procedures to an Xapp (XPages application).

Unfortunately the installation failed and I received an error message ‘no accessible features found for this plugin’. The plugin was not available under application management so from there I could not undo the installation and deleting the plugin from the data\workspace… resulted in an error when starting up Designer.

So I feared a new setup of my development environment but luckily the first result after the query ‘lotus designer remove installed plugin’ was at help. I just repeat them here so I know I have stored it somewhere:

Complete guide to manually uninstalling “plugins” from Lotus IBM Notes

The complete steps to manually uninstalling a Java extension is therefore as follows:

  1. Close Lotus Notes
  2. Open the “features”-directory (<Notes data dir>\workspace\applications\eclipse\features)
  3. Locate the Eclipse features to uninstall.
  4. For each Eclipse feature you need to open it and edit the feature.xml file. Locate the <plugin>-tags and fine the names of the referenced plugins. Note that there might be more than one. Combining the plugin id and the plugin version will give the full filename of the plugin (<plugin id>_<plugin version>.jar).
  5. Delete the Eclipse features you’re uninstalling.
  6. Open the “plugins”-directory (<Notes data dir>\workspace\applications\eclipse\plugins).
  7. Delete the plugin JAR-file(s) you recorded in the step above.
  8. Open the directory containing the platform.xml file (<Notes data dir>\workspace\.config\org.eclipse.update).
  9. Edit platform.xml and go to the end of the file.
  10. Remove each entry you see for the features you deleted in the step above.
  11. Save and close the file.
  12. Since Lotus Notes also keeps a record of which Java extensions to load it’s best to start Notes with some parameters to make it recompute the Java extension registry: notes.exe -RPARAMS -clean

Good news

I posted the problems I experienced on the OpenNTF project page and Paul Withers answered he is working on a newer version of the plugin. Hopefully that one will work brilliantly in Notes 9 clients…

The View free online?

During the cleanup of my paper library with the View magazines I noticed that a lot of articles, including the PFD’s, of The View are indexed by Google and available online. I am not sure if this is a mistake or a seasonal gift from Wellesley Information Services but if you search online most of the older articles appear in the search results.

Older? “What is their use?” you may wonder. Most techniques described are obsolete or a sin, but others are so general (performance, programming best practices) or describe the core (2)of Notes that they are still interesting and fun to read.

Education is the most powerful weapon which you can use to change the world.

In case you wonder how to obtain the titles of the articles that WIS has published you can check for example this site.

Some search tips:

  • Enter titles case sensitive.
  • In case the PDF file does not appear in the results add ‘PDF’ as keyword or use Google Advanced Search where you can specify file type.
  • The locations VOLR6.nsf or viewr5.nsf are pretty unique keywords.

jQuery Mobile 1.3 Panel Widget XPages demo (for download)

The last couple of days I have been ‘playing’ with jQuery Mobile and mostly with the panel widget.

I have made some kind of starter-kit (NSF) to build a great XPages app for tablets/smartphones. I have setup a subset of custom controls which accept properties. A simple form in Notes you can use to setup navigation for header, footer and a vertical menu.

You can download the (zipped) NSF on Dropbox.

Below you can see a sample result:


Please let me know if you experience any problems or if you have suggestions for improvement. Happy coding!

Creating a gallery for the IBM Domino Blog Template – Assistance needed


I found online an old description how to enable image galleries for your/the IBM Domino Blog Template (Not sure if we may label it IBM any longer since they have open sourced it so the ‘community’ may solve issues (I am told).

The description you can find <here>.

Unfortunately the description does not work for me. Are there others who set up successfully image galleries in the Blog template and are willing to share their solutions/approach?
