map:read options
Hi,
I've been trying to use map:read to read a file from a location on the
fs outside the cocoon root.
http://cocoon.apache.org/2.2/core-modules/core/2.2/846_1_1.html
is rather sparse, but I tried:
<map:match pattern="**.msi">
<map:read type="resource"
src="installer.msi"
mime-type="application/octet-stream" />
</map:match>
and alternatives with ../ ./ / aso. nothing seems to work with mvn
jetty:run-war)
The question is: can I use map:read for this, or need I write a little
servlet ?
Tia,
Romain.

the file needs to be outside the .war and either relative to current.dir
(from where the servlet runner got launched) or configurable from
outside the sitemap.
right now I have a little servlet:
public class LittleServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
response.setContentType("application/octet-stream");
String path = System.getProperty("where");
File f = new File(path);
FileInputStream fin = new FileInputStream(f);
// copy fin into response.getOutputStream();
fin.close();
}
}
which does the trick,
but I would like to to something similar using map:read

Where *exactly* do you want to put the file? Should it become part of the web
application or is it located outside?

Robin is right on his suggestion. In order obtain absolute location of your block you could make use
of Input Module provided in COCOON-2145 but this demands patching Cocoon's sources.
Another way is to use properties as Romain already does. In sitemap one can obtain system property
using settings module:
{settings:your_property}
Since 2.2 incorporates Cocoon Spring Configurator sub-project it's very easy to work with various
configuration options. See [2] for more details.

Relative paths are resolved relative to the location of the sitemap,
and in C2.2 the location of the sitemap varies greatly depending on
how you run cocoon during development, deployment etc. In your
production webapp your sitemap will be in the jar file created for
your block.
You could use the directory generator [1] along with ../ in your src
attribute to determine how the relative paths are resolved.
I would suggest you try to determine the absolute path to your webapp
context first and then resolve your path relative to that, you might
want to take a look at using the ContextPathModule [2] which could
help you.

(These are the docs for C2.1, I don't think the comparable

way.)

Yes the file:///C:/some path/installer.msi works
but I would like to have a relative path as the app needs to be relocatable

I think you should be able to, have you tried using an absolute path
to the file like so?
<map:read type="resource"
src="/absolute/path/to/your/file/installer.msi"
mime-type="application/octet-stream" />
or maybe even:
<map:read type="resource"
src="file:///absolute/path/to/your/file/
installer.msi"
mime-type="application/octet-stream" />
