* I'd like to add an external method in a Shared package, but I'm not sure how to do it -- in the Add External Method form, what's the "module name", is it packagename.modulename, packagename/modulename, or what? I've tried various combinations with no luck. * I want to return an image from my external method. What I have which sort of works is: def foo(self, RESPONSE): RESPONSE['content-type'] = 'image/png' return mkimage() where mkimage returns the actual PNG image data. Is this correct? * How can an external method refer to the objects in the Zope app? 'self' above is App -- can I do App.foo and get to object foo? * Is there a way for external methods to read from files on the filesystem? How about write to files on the filesystem? What kinds of sandbox is in place? --david
