[Zope] including arbitrary files in zope products

Hi, I am facing a basic problem with Zope that I'm unable to solve. I want to embed a java applet (jar) in my zope product. The jar file lives as "<Product Basedir>/www/foo.jar" on the filesystem. I want to make this available as "<Product Instance Dir>/foo.jar" inside zope. To include ZPT files, I'm able to do - from Products.PageTemplates.PageTemplateFile import PageTemplateFile ... class Foo(Folder): ... index_html = PageTemplateFile('zpt/index_html', globals()) and make zpt files available inside zope. How can I do the same for arbitrary files such as java archives and others? I don't know how to use the "File" object for this purpose. Can someone please help? Thanks in advance. - Raja
