The Sametime 7.5 Server Installer vs. Sophos Antivirus

When trying to install Sametime 7.5 Server on a computer running Sophos Antivirus be sure to disable the antivirus service while installing. If you don’t you’ll most likely get an error saying “Installation has detected some Domino or Sametime processes already running” and you will be unable to continue. The answer was found in technote 1245237.

Show ‘n Tell Thursday: The missing link for plugging Notes into you Sametime 7.5 plugin (10 January 2007)


When you develop and run plugins for Sametime 7.5 on Windows or Linux you do not use a standard Java Development Kit (JDK) and standard 1.4.2 JVM. Instead you use a slightly modified version called the JCL Desktop JDK and the J9 JVM. The “slightly modified” means that some features have been removed from the JDK to make it “safe” for the Expeditor framework that Sametime 7.5 runs on.

An unfortunate side-effect of this decision is that you cannot use the Notes/Domino API (that is notes.jar or ncso.jar) without resorting to additional libraries. The reason is that the ever present lotus.domino.NotesException inherits from org.omg.CORBA.UserException which is an exception class that has been removed in the modified runtime class library (for more information about lotus.domino.NotesException see my post called Java in Notes/Domino Explained: NotesException).

Fortunately there is a way to remedy that. The solution is to include the ibmorbapi.jar library (can be found in c:Program FilesNotes7Datadominojava on my laptop) in your plugin alongside notes.jar or ncso.jar. The ibmorbapi.jar library is quite large (around 400kb) but I haven’t yet played around with it to see if you could simply get away with including the org.omg-packages.

Now you know why your plugin fails to compile due to indirectly referenced Corba classes.

Anyways – someone who has the ears of the Sametime development team might want to mention this to them. Apart from that – great product and its a joy to develop plugins for Sametime 7.5! 🙂

New article for THE VIEW

After submitting my presentation for my Lotusphere 2007 session (BP308) I’m busy putting the finishing touches on my next article for THE VIEW. The draft is due before I leave for Lotusphere.

The working title is somewhat of a mouthful (“Solving the native library binding problems of the Notes/Domino Java API in the Sametime 7.5 Connect client plug-ins”) and it will probably be changed a couple of times before the article goes to print.

The article is slated for publication in the Mar/Apr 2007 issue of THE VIEW.

Update Site for Sametime – why not simply go local?

As pointed to by Adam Gartenberg there’s a new article out on developerWorks (Creating an update site for your IBM Lotus Sametime Connect plug-ins) on how to create an Update Site for your Sametime client deployment. As much as I would recommend the article I really would suggest that readers don’t stop there and read the entire story on Update Sites at Eclipse.org (How to keep up to date) before venturing into this territory.

Although the developerWorks article does a nice job of describing the subject for the Sametime inclined I would recommend also reading about the Eclipse foundations…

As an aside I also wants to mention that you can test plugins using an Update Site without having a HTTP server ready (although we all have a Domino server ready, no?). You can do this because the Eclipse framework also allows for local Update Sites (i.e. on the same computer or on a network share). To use this feature simply choose “Local Site” instead of “Remote Site” and point your Sametime client to the Update Site directory under your Eclipse workspace. Very nice for testing.
