Hi Raja, some few month ago, I was trying to do the same: Store a java applet class on the file system and load it dynamically from each instance of my product, but I didn't succeeded. You can see my attempt on: http://mail.zope.org/pipermail/zope/2004-May/149813.html Anyway, I solved it storing the java applet on the Zope DB when initializing my product. The code is attached to the message. After adding the file to the Zope DB, then you can use its path on the <applet> tag and it should work.

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
