Hello,

Problem:
My code always tries to acquire a lock before invoking the PUT method. This works well, when overwriting existing resources. It does not work, when creating new resources on Xythos WFS and (according to user reports) on Microsoft IIS. With these servers the PUT method fails and a locked empty file (0 bytes) remains on the server. For details see the attached conversation.


Cause:
Xythos WFS returns a "201 Created" when requesting a LOCK on a non-existing resource, but in org.apache.webdav.lib.methods.LockMethod the method parseResponse ignores the response, if the status is not SC_OK.


Solution:
The following change seems to do the trick:

                 NodeList list = getResponseDocument().getDocumentElement()
                       .getElementsByTagNameNS("DAV:", "locktoken");


Disclaimer:
I do not have the slightest idea, why this second check on the status is in the code anyway.
