Hi François I totally agree about the scheduling library being only part of the solution.
I'm aware of Pallet but I have never used it in anger. The links you have provided look like an interesting angle. I'll start working through them and see if I can figure out an architecture that meets my needs and I can share with you though this list Many Thanks Adrian On 10 Feb 2014, at 16:59, François Rey wrote: > On 10/02/14 16:20, Toby Crawley wrote: >> Actually, Immutant has its own Quartz integration, and is not based on >> quartz-clj.
