Hi, all!
If you have download the ZSM product you could see I put on it a zexp
file with prototype and some other js file and a css file plus images
This was only a prototype solution to bring you the chance to see how
my ideas are but I think this is not a definitive solution
Now my question:
Which is the best zope way to serve this kind of files trying to avoid
any other product dependence?
Thanks a lot!
In the context of Five / Zope3, the static content items are
"resources".  One strategy would be to create a Zope2 product with those
files in a subdirectory, e.g.::

  $ mkdir Products/garito
  $ cd Products/garito
  $ echo "# ZSM product" > __init__.py
  $ mkdir static
  $ cat > static/garito.css
  body {
    background: #CCCCFF;
  }
  ^D

And then register that directory as a "resource directory" via ZCML::

  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:resourceDirectory
        name="garito"
        directory="static"
        />
  </configure>
  ^D

Now, when you start Zope2, you can pull in your static resources via
special URLs, like http://localhost:8080/++resource++garito/garito.css::

  $ cd ../..
  $ bin/zopectl start
  . daemon process started, pid=25240
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /++resource++garito/garito.css HTTP/1.0

  HTTP/1.0 200 OK

In that product, you could also register a template / browser view which
includes your resources, e.g::

  $ cd Products/garito
  $ cat > garito.pt
  <html>
  <head>
   <link rel="stylesheet" type="text/css"
         href="/++resource++garito/garito.css"/>
  </head>
  <body>
  <h1> Garito's view </h1>
  </body>
  </html>
  ^D
  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:page
      for="*"
      name="garito.html"
      template="garito.pt"
      permission="zope2.View"
      />
    <browser:resourceDirectory
      name="garito"
      directory="static"
      />
  </configure>
  ^D
  $ cd ../..
  $ bin/zopectl restart
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /garito.html HTTP/1.0

  HTTP/1.0 200 OK
  Server: Zope/(unreleased version, python 2.4.4, linux2) ZServer/1.1
  Date: Fri, 11 Jan 2008 19:02:05 GMT
  Content-Length: 151
  Content-Type: text/html; charset=iso-8859-15
  Connection: close

  <html>
  <head>
   <link rel="stylesheet" type="text/css"
         href="/++resource++garito/garito.css" />
  </head>
  <body>
  <h1> Garito's view </h1>
  </body>
  </html>
  Connection closed by foreign host.

Which pulls in your static resources.
