I was looking around for some specific JRun information and stumbled upon a Survey put out by the JRun Engineering Team which if you have a few minutes I would encourage you to fill-in. Up-front news on JRun has been pretty
sparse in recent times and this survey is a good sign that all is alive and kicking in the JRun world. Of course JRun is at the center of a lot of Macromedia-Adobe products, not just ColdFusion.

The Survey is located here, it is worth those few minutes of your time.
