    Document hash via CMIS

    Jan Petzold Newbie

      I'm now using CMIS to interact with my Modeshape repository. Doing that I automatically want to hash my documents, something that Modeshapoe supports when using the JCR API:

       

      String docHash = ((StoredBinaryValue) doc).getHexHash();
      

       

      Now I'm adding a document via CMIS and I am unable to add the property cmis:contentStreamHash:

       

      Map<String, Object> fileProperties = new HashMap<String, Object>();
      fileProperties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
      fileProperties.put(PropertyIds.NAME, fileName);
      fileProperties.put(PropertyIds.CONTENT_STREAM_HASH, getSha1ForFile(fileName));
      

       

      Doing that I get the Exception

       

      java.lang.IllegalArgumentException: Property 'cmis:contentStreamHash' is not valid for this type or one of the secondary types!

       

      However CMIS 1.0 should support this:

      Anything I'm doing wrong? How am I going to detect duplicate files effectively without hashing them?
