I am developing an application which needs to access a proprietary business API to access data from their servers. Currently because I don't know how to do that from within Pharo, I have been using Python/COM. But that API is deprecated and expires soon. Now I have to move to an app which accesses via either a C/C++ app which accesses a DLL, a .NET library or a Java jar. There are a number of objects that have to be created from the dll/jar, and a number of interfaces which have to be implemented from the dll/jar. Presently I am studying Clojure in order to work from the Java side. I do not know Clojure or Java. If I could learn sufficient C and do this with NB in Pharo, that would be very nice. I have never done anything like what NB does, so I do not know what all it does or can do. Can Pharo implement the interfaces provided in the DLL in the Smalltalk side? Or would the interfaces have to be implemented on the C side and then Pharo access the objects? Any advise greatly appreciated. Thanks. Jimmie
