-------------------------------------
[~c_koell], Re config: I'm more interested in the setup of the infrastructure.
There has to be an spi2dav Repo setup somewhere for the WebDAV Servlet to act
upon, no?
> Problem with WebDav Client and Repository Server Deployment Model
> -----------------------------------------------------------------

> Key: JCR-4954
> URL: https://issues.apache.org/jira/browse/JCR-4954
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-jcr-server, jackrabbit-webdav
> Reporter: Claus Köll
> Assignee: Manfred Baedke
> Priority: Major
> Fix For: 2.22

> We have one WebApp where we have deployed the SimpleWebDavServlet
> (WebDav-WebApp). From there we connect to a other WebApp where we have
> exposed a Repository through DavEx
> (org.apache.jackrabbit.server.remoting.davex.JcrRemotingServlet)
> and also the RMI-Layer by the RMI Registry (Repository-WebApp)
> Until now we connected over RMI but now we tried to switch to DavEx. The
> Problem is, that we are now unable to unlock a opened WebDav Document.
> The Lock Request in the Repository-WebApp adds a Reference (LockToken) to the
> DavSession so a future Requests can obtain the same DavSession to perform the
> unlock.
> https://github.com/apache/jackrabbit/blob/trunk/jackrabbit-jcr-server/src/main/java/org/apache/jackrabbit/webdav/jcr/DefaultItemCollection.java#L700
> The Reference (Locktoken) looks like
> opaquelocktoken:dccce564-412e-11e1-b969-00059a3c7a00:0089610c-02e5-43cd-bfec-3a90361350f4-0
> It will be generated by the LockTokenMapper
> https://github.com/apache/jackrabbit/blob/trunk/jackrabbit-jcr-server/src/main/java/org/apache/jackrabbit/webdav/jcr/lock/LockTokenMapper.java#L53
> In the WebDav-WebApp the HeaderLockToken will be stored in this format
> opaquelocktoken:dccce564-412e-11e1-b969-00059a3c7a00:opaquelocktoken%3a4403ef44-4124-11e1-b965-00059a3c7a00%3a0089610c-02e5-43cd-bfec-3a90361350f4
> As you can see it will be double wrapped. That's not really a Problem because
> on unlock the WebDav-WebApp removes the prefix
> opaquelocktoken:dccce564-412e-11e1-b969-00059a3c7a00:
> Finally this locktoken will be send from the WebDav-App to the
> Repository-WebApp
> opaquelocktoken:4403ef44-4124-11e1-b965-00059a3c7a00:0089610c-02e5-43cd-bfec-3a90361350f4
> On the Repository-WebApp the JCRWebdavServer will look for a DavSession in
> the Cache based on the lockToken
> https://github.com/apache/jackrabbit/blob/trunk/jackrabbit-jcr-server/src/main/java/org/apache/jackrabbit/server/jcr/JCRWebdavServer.java#L210
> So the problem is that the DavSession whitch have created the Lock, is stored
> with a lockToken that do not match with the incoming lockToken
> Cache-Key-Token:
> opaquelocktoken:dccce564-412e-11e1-b969-00059a3c7a00:0089610c-02e5-43cd-bfec-3a90361350f4-0
> Incoming-Token:
> opaquelocktoken:4403ef44-4124-11e1-b965-00059a3c7a00:0089610c-02e5-43cd-bfec-3a90361350f4
> The DavSession-Cache Key is taken from the LockInfo (LockTokenCheckDigit is
> present)
> https://github.com/apache/jackrabbit/blob/trunk/jackrabbit-core/src/main/java/org/apache/jackrabbit/core/lock/LockInfo.java#L118
> Maybe someone which is familiar with the code of LockTokenMapper can explain
> the two different Scopes (SESSIONSCOPED/OPENSCOPED)
> One possible solution could be to change the code in the LockTokenMapper to
> always return the Node Identifier with the same SCOPE-PREFIX?
