Hi, I have a use case where a daemon needs to read full namespaces from an external jar. I can successfuly access the namespace in the jar with tools.namespace/ find-namespaces-in-jarfile, then from the jarfile, selecting appropriate entries, coercing into readers and then loading with load-

Thanks a lot for the good advice. Pomegranate is very nice and very useful for testing. As for your trick Kevin, certainly nicer that the reflection mess. On Wed, Dec 7, 2011 at 9:00 PM, Kevin Downey redc...@gmail.com wrote: try something like
