Well, you are doing it sort of the other way around then I was thinking of.
Didn't you say that you wanted to use OSGi to run multiple instances of a messy program? My suggestion was to use multiple instances of felix which each would run one instance of the messy program as a bundle. Your example below, on the other hand, is running a single instance of a messy program which has multiple instance of felix embedded... regards, Karl On Tue, Nov 18, 2008 at 8:11 PM, <[EMAIL PROTECTED]> wrote: > Paul, unfortunately the below program has the following output.
