Lots of people might be planning to develop Sametime plug-ins for Hackday. While the Sametime plug-in development environment is really easy to use once you get it set-up it can be tricky to get your environment configured. I always tell people that they must read the instructions in the Sametime SDK very carefully and follow the instructions exactly.
One thing that is slightly annoying is the fact that the Lotus Expeditor Toolkit which is needed to configure your Sametime launch configuration can only be installed with Eclipse 3.4. This is annoying to users of any platform who may prefer to use a more recent version, but it is especially annoying to users of Ubuntu and other variants of Linux because there is a well known bug in this version which can stop Eclipse from launching.
Fortunately there is a simple work around. You just need to edit the eclipse.ini file (which will be ins the same folder where the eclipse executable is installed) and add this line
One you have made this change, eclipse will launch properly and there will be nothing to stop you from doing the coolest Hackday project ever :-)
