Hi, I just created a custom model (book) in Alfresco 3.4.1. It includes a type b:bookType and an aspect b:bookPublication. Now both are present in the repository with the names D:b:bookType (a content type under cmis:document) and P:b:bookPublication (under cmisolicy)respectively. The D:b:boo

Hi Jawwad,

The Alfresco OpenCMIS Extension gives you access to aspects: http://apache-extras.org/p/alfresco-opencmis-extension

Hi and Thanks Florian,

I tried the Alfresco OpenCMIS Extension but now im having a class cast exception. My code is:

Document existingBook = (Document)session.getObject(bookTypeDoc);
      AlfrescoDocument alfDoc = (AlfrescoDocument)existingBook;
      alfDoc.addAspect("P:b:bookPublication");
      if(alfDoc.hasAspect("P:b:bookPublication")){
         properties.put("b:publishedBy", "Custom CMIS");
         alfDoc.updateProperties(properties);
      }‍‍‍‍‍‍‍

Here the Document im retrieving is of a custom type (D:b:bookType). and the exception is:
"
Exception in thread "main" java.lang.ClassCastException: org.apache.chemistry.opencmis.client.runtime.DocumentImpl cannot be cast to org.alfresco.cmis.client.AlfrescoDocument"
On this code

AlfrescoDocument alfDoc = (AlfrescoDocument)existingBook;‍

Same happens when I try to cast a general non-custom type. Can you plz help me on this?

Thanks in advance.

Hi,

Sorry, I found my mistake . I was missing this session parameter entry.

params.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");‍

Thanks again
