I am trying to connect to SharePoint 2013 using Apache Chemistry CMIS Web services binding. I have given valid WSDL url.

Sometimes I am able to make a valid connection and perform CMIS operations. But sometimes I get the following exception trace :

org.apache.chemistry.opencmis.commons.exceptions.CmisRuntimeException: Error: The server sent HTTP status code 401: Unauthorized at org.apache.chemistry.opencmis.client.bindings.spi.webservices.ObjectServiceImpl.createDocument(ObjectServiceImpl.java:92) at org.apache.chemistry.opencmis.client.runtime.SessionImpl.createDocument(SessionImpl.java:751) at org.apache.chemistry.opencmis.client.runtime.SessionImpl.createDocument(SessionImpl.java:882) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite$PojoCachedMethodSite.invoke(PojoMetaMethodSite.java:189) at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite.call(PojoMetaMethodSite.java:53) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:45) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:108) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:128) .................................

What is the reason for this mixed behaviour. And how do I get rid of this exception

  • Are you using NTLM authentication? If so, switch to basic authentication an try again. And, if you can, use the AtomPub binding. It's faster. – Florian Müller May 08 '16 at 08:18
  • You have to enable Basic authentication on the server side. NTLM will never work flawless with CMIS write operations. Also, the upload limit is a server configuration. – Florian Müller May 09 '16 at 07:16
  • I found that With Web Services Binding I am not able to upload a file > 52 MB. If I try to upload a large file >52 mb , it gives me 400 bad request error. I will try enabling basic authentication on server side. Thanks for your help in advance. – Nikita Bansal May 09 '16 at 10:27
  • I enabled basic authentication on sharepoint server side. But didnt work :-( – Nikita Bansal May 09 '16 at 10:57
