I'd heard about this nice product throught a collegue of mine, and I have some questions in which I hope someone can answer me :-) Me and someothers are working with thermodynamic modelling and alogorithms. One year ago we saw the need of distribution of our code, which means that we made our thermodynamic calculation engine as a separate module, and other modules could use this one (The thermodynamic core could also access other modules again). All communication between the modules are in CORBA. When we want to send data to the modules, id.e. modellparameters we use XML. Later we created a dynamic GUI language for manipulation of the parameters and other stuff, inserting values into the XML tree and calling the different module functions. Its our glue module. (which is more or less does the same as Zope (Correct me if I'm wrong.). So to my question: This summer we built a GUI client using java which communicated with our gluemodule. This is a solution we want to have. Is it possible in Zope to accomplish this in some way. (Id.e communication without using a web client) Best regards, Geir Arne Evjen
