Setting an aspect property using CMIS

srowsell — Thu, 12 Jun 2014 14:46:52 GMT

So I'm working with Alfresco 4.1.7.3, and therefore CMIS 1.0, which means that I'm using the Alfresco CMIS Extension (as I have to work with aspects). I've been figuring out what I can from online resources, and I bought the book by Jeff Potts and others, which is excellent. But I'm trying to chan

Since you are using cmis1.0 secondaryTypes is no avialable ,you can use Aspect Extensions,add update aspect properties like folloing


   List<CmisExtensionElement> extensions = new ArrayList<CmisExtensionElement>();

        CmisExtensionElement valueElem = new CmisExtensionElementImpl(CMISConnector.ALFRESCO_EXTENSION_NAMESPACE, "value", null, "Accounting");
        List<CmisExtensionElement> valueElems = new ArrayList<CmisExtensionElement>();
        valueElems.add(valueElem);

        List<CmisExtensionElement> children = new ArrayList<CmisExtensionElement>();
        Map<String, String> attributes = new HashMap<String, String>();
        attributes.put("propertyDefinitionId", "ra:department");
        children.add(new CmisExtensionElementImpl(CMISConnector.ALFRESCO_EXTENSION_NAMESPACE, "propertyString", attributes, valueElems));

        List<CmisExtensionElement> propertyValuesExtension = new ArrayList<CmisExtensionElement>();
        propertyValuesExtension.add(new CmisExtensionElementImpl(CMISConnector.ALFRESCO_EXTENSION_NAMESPACE, CMISConnector.PROPERTIES, null, children));

        CmisExtensionElement setAspectsExtension = new CmisExtensionElementImpl(CMISConnector.ALFRESCO_EXTENSION_NAMESPACE, CMISConnector.SET_ASPECTS, null, propertyValuesExtension);
        extensions.add(setAspectsExtension);

I suggest you use a utils class org.alfresco.cmis.client.impl.AlfrescoAspectsUtils,which is very convenient to manipulate Aspect Extensions

kaynezhang…

Thanks for your reply. It's not clear to me where the CMISConnector class comes from. It looks like it ought to be in org.alfresco.opencmis, but that import doesn't get me that class.

CMISConnector class is used by alfresco server to adapt Alfresco and OpenCMIS。
I don't think you will need it in openCmis Client.

I ask because it's there in your sample code, and if it's not an imported class it's not clear how it works.

I'm sorry ,my mistake.We don't need CMISConnector class, we only need several constants that define in it,they are ALFRESCO_EXTENSION_NAMESPACE，SET_ASPECTS，PROPERTIES.I have already extract them.
I have modified and tested the code ,you can copy and modify according your requirement


      String ALFRESCO_EXTENSION_NAMESPACE = "http://www.alfresco.org";
      String SET_ASPECTS = "setAspects";
      String PROPERTIES = "properties";
      String VALUE = "value";
      String PROPERTY_DEFINITION_ID="propertyDefinitionId";
      String PROPERTY_STRING="propertyString";
      String servalUrl = "http://localhost:8080/alfresco/cmisatom";
      String userName = "admin";
      String password = "admin";

      Session session = getSession(servalUrl, userName, password);
      AlfrescoDocument alfDoc = (AlfrescoDocument) session
      .getObjectByPath("/TESTFOLDER1/20130822.doc");
      
      Properties properties = new PropertiesImpl();
        List<CmisExtensionElement> extensions = new ArrayList<CmisExtensionElement>();

        CmisExtensionElement valueElem = new CmisExtensionElementImpl(ALFRESCO_EXTENSION_NAMESPACE, VALUE, null, "Accounting"); //property value of custom property ra:department is accounting
        List<CmisExtensionElement> valueElems = new ArrayList<CmisExtensionElement>();
        valueElems.add(valueElem);

        List<CmisExtensionElement> children = new ArrayList<CmisExtensionElement>();
        Map<String, String> attributes = new HashMap<String, String>();
        attributes.put(PROPERTY_DEFINITION_ID, "ra:department");//property name is ra:department
        children.add(new CmisExtensionElementImpl(ALFRESCO_EXTENSION_NAMESPACE, PROPERTY_STRING, attributes, valueElems));

        
        List<CmisExtensionElement> propertyValuesExtension = new ArrayList<CmisExtensionElement>();
        propertyValuesExtension.add(new CmisExtensionElementImpl(ALFRESCO_EXTENSION_NAMESPACE, PROPERTIES, null, children));

        
        CmisExtensionElement setAspectsExtension = new CmisExtensionElementImpl(ALFRESCO_EXTENSION_NAMESPACE, SET_ASPECTS, null, propertyValuesExtension);
        extensions.add(setAspectsExtension);
        System.out.println(extensions);
        properties.setExtensions(extensions);
        String repId = session.getRepositoryInfo().getId();
        Holder<String> objectIdHolder = new Holder<String>(alfDoc.getId());
        session.getBinding().getObjectService().updateProperties(repId, objectIdHolder, null, properties, null);
