Document property update CMIS

sumantapakira — Wed, 16 Jan 2013 22:08:53 GMT

Hi All,I'm trying to update property of a document in Alfresco repository using CMIS. For that I've written below code but I'm getting error Property 'cm:description' is not valid for this type! Folder newFolder = root.createFolder(folderProperties);String name = "testdata5.text";Map<String, Obje

The cm:description property is part of the cm:titled aspect. In order to use OpenCMIS with content models that leverage aspects, you must use the OpenCMIS Alfresco Extension available at Google Code. The home page for that project shows an example of how to set the cm:description property.

Thanks Jeff,

As per the instruction, I've included alfresco-opencmis-extension-0.4.jar in classpath and modified code as below -
Folder newFolder = root.createFolder(folderProperties);
Map<String, Object> contentProperties = new HashMap<String, Object>();
contentProperties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,P:cm:titled");
contentProperties.put(PropertyIds.NAME, name);
contentProperties.put("cm:description", "Test");
ContentStream contentStream = new ContentStreamImpl(name, new BigInteger(content), "text/plain", stream);
Document document = newFolder.createDocument(contentProperties, contentStream, null);

But still I get error : Type 'cmis:document,P:cm:description' is unknown!

Could you please advice what is wrong here?

Your code runs fine for me against Alfresco 4.2.c. It is strange that the code you pasted has the correct objectTypeId ("cmis:document,P:cm:titled") but the error message you are getting has the property, not the type ("Type 'cmis:document,P:cm:description' is unknown!").

Can you have the correct string for the objectTypeId property and that you are not accidentally overwriting that property somewhere in the code before you call createDocument?

Also, I note in your curl example that you are using the deprecated, web script-based CMIS URL (/alfresco/s/cmis) instead of the OpenCMIS-based URL (/alfresco/cmisatom). If you are running Alfresco 4 or higher, please switch your URL unless you have a good reason for using the old URL.

Hi Jeff,

In my code I'm using OpenCMIS based URL and I'm using 4.2.c
In my code I'm not overwriting property. First I'm creating folder and then document. Below is the code -

Folder root = session.getRootFolder();
        Map<String, Object> folderProperties = new HashMap<String, Object>();
        String foldername="testfolder";
        folderProperties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:folder");
        folderProperties.put(PropertyIds.NAME, foldername);
Folder newFolder = root.createFolder(folderProperties);
        Map<String, Object> contentProperties = new HashMap<String, Object>();
        contentProperties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,P:cm:titled");
        contentProperties.put(PropertyIds.NAME, "TestName");
        contentProperties.put("cm:description", "Test");
         byte[] content = " Testdata".getBytes();
        InputStream stream = new ByteArrayInputStream(content);
        ContentStream contentStream = new ContentStreamImpl(name, new BigInteger(content), "text/plain", stream);

       Document document = newFolder.createDocument(contentProperties, contentStream, VersioningState.MINOR);
Error:
org.apache.chemistry.opencmis.commons.exceptions.CmisObjectNotFoundException: Type 'cmis:document,P:cm:titled' is unknown!

Hi sumantapakira,

How do you getting the session object?

I think the problem with session object, Provide your code to get the Session Object.

Hi narithota,

Below code I've written to create session -

private static final String CMIS_ENDPOINT_TEST_SERVER = "http://localhost:8080/alfresco/cmisatom";
private Session session;
public String getCmisClientSession(){
       String repoName=null;
       try{
       SessionFactory factory = SessionFactoryImpl.newInstance();
        Map<String, String> parameters = new HashMap<String, String>();
        parameters.put(SessionParameter.USER, "admin");
        parameters.put(SessionParameter.PASSWORD, "admin");
        // connection settings
        parameters.put(SessionParameter.ATOMPUB_URL,
                CMIS_ENDPOINT_TEST_SERVER );
        parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB
                .value());
         session = factory.getRepositories(parameters).get(0).createSession();
    }

Please advice

You are missing:


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

Which needs to be called before you instantiate the session.

Thanks Jeff,
So this is specific to Alfresco session but if I want to create session for other content management system like Documentum then this will not work I guess. Please let me know your thoughts. I want to make it as vendor repository independent.

I am very interested in topic.
Any followups?

thanks for the tip with "alfresco/cmisatom" vs "alfresco/s/cmis". I was using the old URL all the time.
The old CMIS interface did not guess the right mime type of a content stream, not even if the mimetype
was "application/octet-stream". The new one does. (using V4.2.d)

thanks a lot
