I think everything should work in J7 except for cdf for the reasons Bill pointed out. In Windows post XP I think you could do your own call to the windows api to unload your dll (making development testing easier). Not sure of the call name but it is something like freelibrary. I'm puzzled why this started out as a question about jdll.h which is about the J dll api and would seem to have little relevance to building and using your own dll.
