I've been using it mainly because Rich has recommended it: http://clojure-log.n01se.net/date/2008-10-26.html#15:33 http://clojure-log.n01se.net/date/2008-11-22.html#11:58 > It's primary and sole intent is to hold extensions to the java API > that then would be loaded with the core java APIs. Is there any documentation suggesting it should not be used the way I'm using it? The Sun docs I've read so far don't seem to forbid it. > That's certainly why you're having problems when you mess up the > dependencies in places where there is a hierarchy of classloaders > involved : clojure-contrib was loaded with the "main classloader" > along with java core libraries, and clojure was loaded with a "child" > classloader.

But even this is not a problem when loading code from .clj files instead of .class files, which may be why I haven't run into it much. ...and actually doesn't it have to be a bit more complicated than that? Otherwise I would have been unable to load *any* classes named only in the java.ext.dirs via the -cp-loaded clojure REPL, right? Anyway, I have a solution (in complete violation of your warnings!) that's working nicely now. :-) I have a cp-common directory, as well as one or more cp-<proj> dirs, where a <proj> can specify either just a clojure branch (master, 1.0, chunks, or an application project I'm working on. In either case, it can contain a link to the specific clojure jar I want. For example, cp-1.0 can include links to both clojure-1.0.jar and the 1.0 branch of contrib (once it exists), while clojure-master can include links to the lastest pull of each. So is this still the wrong way? Is the right way really to launch ruby so I can launch clojure!? --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
