shallow traversal of multiple contact folders

["Stephan Steiner"]

Hi

Since I cannot get deep traversal to work (see my post from September 9th) 
when using user A's credentials to access user B's contacts (even though A 
has the rights to access B's contacts, including every subfolder in the 
contact folder), I figured I'd try something else:

Do a hierarchical traversal of a user's main contact folder 
(http://exchange-server/exchange/user@domain/Contacts/) to get back a list 
of subfolders. Unfortunately that only results in one level of contacts 
(e.g. if you have a hierarchy like this:

                                exchange-server/exchange/user@domain/Contacts/Subfolder1">http://exchange-server/exchange/user@domain/Contacts/Subfolder1
                                exchange-server/exchange/user@domain/Contacts/Subfolder1/SubSubfolder">http://exchange-server/exchange/user@domain/Contacts/Subfolder1/SubSubfolder
                                exchange-server/exchange/user@domain/Contacts/Subfolder2">http://exchange-server/exchange/user@domain/Contacts/Subfolder2
                                exchange-server/exchange/user@domain/Contacts/Subfolder2/SubSubfolder">http://exchange-server/exchange/user@domain/Contacts/Subfolder2/SubSubfolder
)

A hierarchical traversal would only return Subfolder1 and Subfolder2, but 
not Subfolder1/SubSubfolder and Subfolder2/Subfolder. That can be alleviated 
by doing another traversal on the resulting urls of the hierarchical 
traversal of the main contact folder, but obviously it's highly ineffective.

Anyway, I figured for starters I'd settle for the main folder and the first 
level of subfolders.

Then I constructed a query like this:

String queryString = "<?xml version=\"1.0\"?><D:searchrequest xmlns:D =
\"DAV:\" >"
                        + "<D:sql>SELECT "
                        + "\"urn:schemas:contacts:givenName\",
\"urn:schemas:contacts:sn\", \"urn:schemas:contacts:telephoneNumber\",
\"urn:schemas:contacts:mobile\", \"urn:schemas:contacts:homePhone\""
                        + " FROM SCOPE(" + scopeString + ) "
                        + "WHERE \"DAV:ishidden\" = false AND
\"DAV:isfolder\" = false </D:sql></D:searchrequest>";

with scopeString being
String scopeString = "'shallow traversal of 
\"                                exchange-server/exchange/user@domain/Contacts/\"">http://exchange-server/exchange/user@domain/Contacts/\";', 
'shallow-traversal of 
\"                                exchange-server/exchange/user@domain/Contacts/Subfolder1\"">http://exchange-server/exchange/user@domain/Contacts/Subfolder1\";', 
'shallow-traversal of 
\"                                exchange-server/exchange/user@domain/Contacts/Subfolder2\"">http://exchange-server/exchange/user@domain/Contacts/Subfolder2\";'";

But when I make that query, I get stuck with a 404 error.

If I limit my scopeString to contain just one of the above three urls 
(regardless of which one), it works out just fine.

Any ideas what might be going wrong here?
