getting started
I'm still trying to 'figure out' Slide, and I think I'm missing a few things. Or, at least I'm missing the one big thing that makes everything else fall into place.
I want to use Slide as the back end for a content management application. We are going to store media files (.wav files, images etc.). The users will be able to go to the web site, look at (or hear) the current version of the media. If they want to make a change, they can upload a new version of the media file and we drop it into Slide. They also will be able to potentially see (hear) all old versions of the file.
We also want to be able to group files together and then drop labels on those files and then get the labeled version of a file. So, maybe Hello.wav is currently on version 1.6, but 1.3 is labeled 'Production'. Without knowing the version number, we want the user to be able to get 'Production'.
So, I have been playing with the WebdavResource, and it doesn't look like there is any way to use that class to do any of the labeling/getting that we want to do. I can call the 'reportMethod(...)' on the WebdavResource, and it will return the path to each version of a file and I can then get that version, but I can't figure out how do use the labeling.
So, if anyone could fill in what I am missing, I would really appreciate it. Do people write their own client Socket to connect to the Servlet and push over HTTP/Webdav Headers to do what they want to do?
Thanks, Chris

Ah. Thanks for the clarification - I'd seen (at some distant point in
the past) a reference to it being deprecated, but had forgotten the
details.

No, not the LABEL feature per se, but the "Label" request header (it's
incompatible with HTTP/1.1 because in some way it behaves like a
variant, but then sometimes doesn't). See
<http://www.webdav.org/deltav/protocol/rfc3253-issues-list.htm>, issue
"8.3_ LABEL_HEADER".

I did this by subclassing WebdavResource. I added an instance variable
"private String label;", along with a getter and setter.
Then, I overrode getMethodData() to call
method.setHeader("Label", label);
if label was non-null. Fairly simple.
Though apparently the whole Label thing is a deprecated feature of webdav...

Chris,
You will want to look at the PropFind/PropPatch methods for
setting/retrieving properties. You can add in your own custom properties
and namespace as well. Some of the functions in WebdavResource are a bit
limiting, but you can always call the methods directly from the methods
class if need be. Worst case you can write your own client library to do
the HTTP calls.

My bad - the method header went missing :)
pURL = URL for which you want to get labeled version
pLabel = Label string
public String getVersionByLabel(String pURL, String pLabel)

Try this code. It will return the URL for the resource that has a given
label. You can then do a get on the href returned.
boolean found = false;
String version = null;
WebdavResource res = getResource(pURL);
PropertyName name = new PropertyName("DAV:", "label-name-set");
Vector v = new Vector();
v.add(name);
Enumeration enum = res.reportMethod(res.getHttpURL(), v);
while (enum.hasMoreElements() && !found)
{
Object o = enum.nextElement();
if (o instanceof ResponseEntity)
{
ResponseEntity ent = (ResponseEntity)o;
Enumeration enum1 = ent.getProperties();
while (enum1.hasMoreElements() && !found)
{
Object o1 = enum1.nextElement();
if (o1 instanceof BaseProperty)
{
BaseProperty prop = (BaseProperty)o1;
NodeList list = prop.getElement().
getElementsByTagNameNS("DAV:", "label-name");
for (int i = 0; i < list.getLength(); i++)
{
String temp = list.item(i).getFirstChild().
getNodeValue();
if (temp.compareTo(pLabel) == 0)
{
found = true;
break;
}
}
}
}
if (found == true)
{
version = ent.getHref();
}
}
}
return version;
