[Zope] newbie - howto get a local javascript file to become a object in Zope

Hi First I would like to excuse those stupid questions, but allthough Im trying its hard to find the information elsewhere. I have a javascript file located at my local harddisk and I want it to become an object in zope. I have already tried to use manage_addFile, but it doesnt seem to find the file. In Zope mangement view its easy enough to create a txt-file and get it on working, but when I want to do the exact same thing in a Product created with Python, it just wont! So far I have also tried to find some other objects that I might use instead of manage_addFile, but havent succeded yet. any idears? Regards Danny Nielsen
