I'm new with CMIS and Alfresco and I got this error when in try to connect to my Alfresco's repository using AtomPUB binding. I have no idea about the source of my problem. Is it unless a functionality ? Is it my Credential ? When I install it, I choose only : - Alfresco community - Solr4

How should I do if I want to use web services ? Should I install a specific plugin in my Alfresco ?

I got with error :

SLF4J: Class path contains multiple SLF4J bindings.

I found the solution, it's because of Alfresco's version. Since the V4.x the url of the AtomPUB is http://localhost:8080/alfresco/cmisatom.
