Hello,
Ok, I came up with a solution that I like; today I spent a little while
making it so I don't have to load things into memory before they are served.
Now it works quite nicely for serving out js/css/gui pics. I won't post
what I did right now, as I haven't really cleaned it up and I'm ashamed of
how it looks at the moment, but I'll post the usage of it to see if anyone
would like to use it after I clean it up:
...
from util import FileSystemResource #it's just in a utility module for my
current project at the moment
...
MyZopeObject(Implicit,Item,Whatever):
#"js" and "css" are paths that are considered relative to my package
directory (not the cwd for zope). It can be absolute too, if desired.
js = FileSystemResource("js","Javascript Repository")
css = FileSystemResource("css","CSS Repository")
Now, say that there is ext-all.js in a directory called
"/path/to/zope/Products/MyProduct/js/". You could then link to the java
script file by going to http://domain.com:8080/myZopeObject/js/ext-all.js.
In particular, in dtml, I have a standard_html_header that looks something
like this:
==standard_html_header.dtml==
This is a title.
==!End standard_html_header.dtml==
Then in MyZopeObject, I wrap up my DTML in a method like so:
.
_main = DTMLFile("dtml/main",globals())
def main(self):
main_js=["ext-all.js","main.js"]
return _main(self.REQUEST,local_js = main_js)
I did the whole local_js thing so I could control what JS got dropped into
what pages without having to write a different header for each one. I will
probably also do the same thing for the css just in case I want
page-specific css files.
This is what I'm doing at the moment, and it's working great. If this would
be useful to someone else, I'll give it more than an hour and a half of
thought, rewrite it more intelligently, and make it available. Otherwise,
thanks to everyone for their comments!

Matt,
Please keep us updated on your strategy for serving extjs. I am also
considering making my application a product for distribution but I was
thinking along the lines of an install script for macs that would set
up the apache webserver. I also like your approach.
BTW, I haven't done it, but couldn't you just store an object in zodb
that has a pointer to your video on the filesystem and access the
video via a zope product? But maybe that is what LocalFS does, I
haven't checked.
see ya in the extjs forum. Just do a search for "zope"
