No document parents with OpenCMIS and /alfresco/cmisatom

lukasv — Mon, 09 Apr 2012 18:57:08 GMT

I am having trouble getting the parent folder for a document using Apache Chemistry OpenCMIS. The problem I am experiencing seems like it has more to do with Alfresco than OpenCMIS, but if I am posting this in the wrong place, I apologize.I am using OpenCMIS 0.6.0 and Alfresco 4.0.0. I have been u

I ran your code as-is against the cmisatom URL (with a different node ref) and got:

Found document: workspace://SpacesStore/89af08c8-499e-4010-983a-7746f7d418db
Found 1 parents
   workspace://SpacesStore/9853f8c5-b1bb-4bb1-bca7-3f0999033469‍‍‍

I also tested the getObjectParents() call in cmislib against Alfresco and it too was successful.

What specific version of Alfresco are you testing against? I ran your code against 4.0.d Community, WAR-only, Lucene.

Confirmed your code is also fine against 4.0.0 Enterprise.

I'm testing against Community - v4.0.0 (b 3835), WAR only.

I don't know what could possibly be the problem. I will see if we can update to the latest Community version.

Thanks for looking into it!

Interesting, the code runs fine against 4.0.b Community (WAR-only, Lucene) for me.

Let's see if we can fine-tune this test a bit…
- How did you create your test document (via CMIS or the UI)? I created mine via Share as admin.
- Is it an instance of a custom type or just cm:content? My test doc is an instance of cm:content (cmis:document).
- Where in the repo does it live? Mine lives in Company Home/test
- When you run your OpenCMIS code, are you running as admin or some other user? I'm running as admin.
- If you are running as some other user, how are the permissions set in the test folder and that folder's ancestor folders? My test folder has no local permissions set and inherits permissions from Company Home, which are standard, OOTB permissions.

Ok, we upgraded to 4.0.d (Community - v4.0.0 (4003), WAR only, I'm not sure about the Lucene part?). It looks like we're having some trouble with our Solr configuration after the update, so that might have something to do with it…

In the meantime, I will try to answer your questions. Before I get to that though, I updated and re-ran my test.

Full test code:

@Test
public void testDocParents() {
   Session session = getSession("http://alfserver:8080/alfresco/cmisatom");
   
   // Test file added via CMIS
   testGetParents(session, "workspace://SpacesStore/ce05803c-858f-43bb-bedf-8df0849a79f9");

   testGetParents(session, "workspace://SpacesStore/f6d3c572-30ae-4755-9944-71ca25331620");
}

private void testGetParents(Session session, String objectId) {
   try {
      System.out.println("Searching for document: "+objectId);
      CmisObject obj = session.getObject(objectId);

      if(obj instanceof Document) {
         Document doc = (Document)obj;
         printProps(doc);
         List<Folder> parents = doc.getParents();
         System.out.println("Found "+parents.size()+" parents");
         for(Folder folder : parents) {
            System.out.println("\t"+folder.getId());
         }
      }
   } catch(CmisRuntimeException e) {
      //e.printStackTrace();
      System.out.println(e.getErrorContent());
   }
   System.out.println();
}

private void printProps(CmisObject obj) {
   List<Property<?>> props = obj.getProperties();
   
   for(Property<?> property : props) {
      System.out.println("\t"+property.getId()+" = "+property.getValueAsString());
   }
}

private Session getSession(String connectionString) {
   Session session = null;
   
   // default factory implementation

   Map<String, String> parameters = new HashMap<String, String>();

   parameters.put(SessionParameter.USER, alfrescoUser);

   System.out.println("ATOMPUB_URL = "+connectionString);
   parameters.put(SessionParameter.ATOMPUB_URL, connectionString);
   parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

   // get repositories
   long start = System.currentTimeMillis();
   List<Repository> repositories = factory.getRepositories(parameters);
   session = repositories.get(0).createSession();
   session.getDefaultContext().setCacheEnabled(false);
   
   return session;

I am now testing against two files. The first one was added via CMIS, the second one was added via Alfresco Share. It's interesting to note that the file added via Share fails completely when using the /alfresco/cmisatom service. That might have to do with our Solr installation problem?

Anyway, the answers to your questions:

How did you create your test document (via CMIS or the UI)?
- Both
Is it an instance of a custom type or just cm:content?
- I have not created a custom type, so I assume it is just cm:content.
Where in the repo does it live?
- It's in Company Home/Sites/roiweb-file-share
When you run your OpenCMIS code, are you running as admin or some other user?
- I am using a service account user.
If you are running as some other user, how are the permissions set in the test folder and that folder's ancestor folders?
- The service account is a member of a group that has "Site Manager" rights to the repository root. All sub-folders inhert permissions from Company Home/Sites/roiweb-file-share

I hope this helps!

Okay, this was helpful and I think I see at least part of the problem. I should have added "is your object versioned?" to my list of qualification questions!

In your first test, you appear to be retrieving an object that has been versioned, and the object you are getting back is not the latest version as evidenced by isLatestMajorVersion being set to False.

In the later test, you are grabbing the same object, but you are getting version 8.0 back.

The reason this is happening is because when you are calling getObject with a series ID, not a CMIS object ID. The CMIS object ID will have a version label appended to it, which you can see in your property dump.

I doubt that versioned objects are able to find their parent which is why you are getting no result back.

Try adding this piece of code immediately after your cast of obj to doc:


doc = doc.getObjectOfLatestVersion(false);‍‍

This will make sure you get the latest version of the object and that version should be able to give you its parent.

Ah, yes. I was going to mention that our repository is versioned, but I forgot to include that in my post. Sorry about that!

Anyway, that seems to have fixed the problem. Now the test results are inverted such that /alfresco/service/cmis is no longer working, but I guess that's not an issue since it is deprecated anyway.

Do you have any idea why I'm getting an error when trying to retrieve the document added via Share? Is that related to this problem, or something else entirely?

Re: No document parents with OpenCMIS and /alfresco/cmisatom

jpotts — Tue, 10 Apr 2012 21:31:09 GMT

Not sure on the doc added via Share. My test doc was created via Share and it works fine.

If you are trying to get Solr to work and you haven't been successful, I suppose that might be a clue. But if you still have Lucene set as your search engine that probably isn't the cause.

Does it fail for every document added via Share, regardless of site, folder path, or user?

Hi all,

I have similar problem. I've switched from use http://localhost:8080/alfresco/service/cmis to http://localhost:8080/alfresco/cmisatom cause i've problems sending huge files to Alfresco (>150 Mb). I start by saying that i've created one tenant with (user,userpass), using tenant console, and i have to manipulate object into tenant!!!

When i was using first url this code worked:

Map<String, String> parameter = new HashMap<String, String>();

// user credentials
parameter.put(SessionParameter.USER, "user");
parameter.put(SessionParameter.PASSWORD, "userpass");

// connection settings
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:8080/alfresco/service/cmis");
parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

// set the alfresco object factory
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");

// create session
SessionFactory factory = SessionFactoryImpl.newInstance();
Session session = factory.getRepositories(parameter).get(0).createSession();
Folder parent = session.getRootFolder();‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now i've changed only

parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:8080/alfresco/cmisatom");‍

And

Folder parent = session.getRootFolder();‍

throws

org.apache.chemistry.opencmis.commons.exceptions.CmisRuntimeException: Object Info is missing!‍

I think that there are some problems with permission because if login with (admin,admin) i can retrive rootFolder and navigate its childern.

Hints?

Regards and Thank u
