Re: NPE trying to session.getRootFolder

I'm using

Alfresco Community v4.0.0
(4003) schema 5025


The web service url is

http://some.local.host.com:9080/alfresco/cmisws/RepositoryService?wsdl

I decided to build a standalone app that just tested that one thing, soit would be easier to test (the real thing is part of a web app onweblogic)

It works fine in the standalone app. I'm now thinking that it's a quietjar conflict, as i had to download a bunch of jars that apparently

wls was providing.

I'm going to stuff all the jars i downloaded into WEB-INF/lib and seewhat happens.

Hi Dave,

Looks like the transferred XML is somehow corrupt. All properties
became extensions.
Would it be possible to capture the response from the Alfresco server?
Which Alfresco version are you connection to and which Alfresco CMIS
URL did you use?


Thanks,

Florian

Greetings,

   I am running into a NPE trying to get the root folder from an
Alfresco cmis thru chemistry 0.10.0.

I'm assuming that there is some sort of configuration missing on my
part, but i'm not sure how to debug further.

Basically, when calling Session.getRootFolder it gets to

SessionImpl getObject(ObjectId objectId, OperationContext context);

where it fetches ObjectData, that looks like this:

Object Data [properties=Properties Data

[properties=[]][extensions=[{http://docs.oasis-open.org/ns/cmis/core/200908/}propertyId

It then switches on the objectData's baseTypeId

which uses the entry in the properties.properties object as

 PropertyData<?> property =
properties.getProperties().get("cmis:baseTypeId");

but as you can see above the properties.properties collection isempty.


since the value returned is null, the switch NPEs on me.

So i'm not sure why the properties.properties collection is empty.

Any help would be greatly appreciated.
