Java Api CMIS - change attribuite 'cm:creator' = 'cmis:createdBy'

dmralfing — Mon, 03 Feb 2014 10:26:17 GMT

I´m implementing a migration with the CMIS Java Api for Alfresco 4.1. The problem is that I have to migrate also the values that indicates the owner of the files, so I have to put values in the attributes cm:creator and cm:modifier - that matches with cmis:createdBy and cmis:lastModifiedBy - .Does i

No, those are read-only.

Yes, it´s that I though. But it's a migration from another CMS to Alfresco, and I have to carry this
information also to the Alfresco CMS to identify at least the owner of the elements.
Maybe any job or behaviour that makes any changeOwner function done since the Alfresco system?. I don´t
mind how, but I must do it. Somebody knows how I can?

You can customize a webscript to modify node permission(owner) .In you webscript call

setOwner(String userId) /code> method of ‍

ScriptNode API</code>
or
void setOwner(NodeRef nodeRef, String userName) mehod of <code> public servcie api

Thank you so much!. I guess this function changes the attribute cm:creator, but…Is it possible to do something to change the attributes "cm:modifier", "cm:created" and "cm:modified"?. I need it because I want to have the same information in this attributes that I have in the source Content Server.
Thank you so much again!

No,it will change cmwner property of ownable aspect, if this node dosen't have this aspect ,the aspect will be added first.
cm:modified,cm:modifier are read only ,why do you want to modify them?

I want it because it is a migration from another content server that it already has its attributes that indicates this things - last user that modified, creation date… - . So then, if I want to migrate this information, I should need to create new customized attributes replicating all of this instead of use them. That would not be efficient, neither ellegant..

The cmis specification says these properties are read only. Sorry.

http://docs.oasis-open.org/cmis/CMIS/v1.1/cs01/CMIS-v1.1-cs01.html

You could upload via another protocol, or perhaps run something on the server to fix the dates after upload via cmis.

You can change these properties using javascript api 、webscript api、or java public api.

Ok, fine, but can you tell me how?, I don´t mind web script, Java API, whatever you'd rather, but please give me any way to do it, I don´t mind how, it isn´t necessary doing it with CMIS.
Thanks!

You can modity these propertis by java api or customize a java backed webscript .

First you should disable auditable aspect ,this will allow you to change properties of cm:auditable aspect


policyBehaviourFilter.disableBehaviour(nodeRef, ContentModel.ASPECT_AUDITABLE);

// Update properties of cm:auditable aspect
nodeService.setProperty(nodeRef, ContentModel.PROP_CREATOR, "xxxxxx");
nodeService.setProperty(nodeRef, ContentModel.PROP_MODIFIER, "xxxxxx");

// Enable auditable aspect
policyBehaviourFilter.enableBehaviour(nodeRef, ContentModel.ASPECT_AUDITABLE);
‍‍‍‍‍‍‍‍‍‍

I suggest you customize a java backed webscript . after creating a node using cmis api ,you call your webscript api to modify these properties.

In the behavior the class takes OK the policyBehaviourFilter with the getter. I do this:


   public void beforeUpdateNode(NodeRef arg0) 
   {
          policyBehaviourFilter.disableBehaviour(arg0, ContentModel.ASPECT_AUDITABLE);
   }
   public void onUpdateNode(NodeRef nodo) 
   {
   //if I uncomment this lines below, it takes the values fine but I don´t want to put this values in the behavior
   //nodeService.setProperty(nodo, ContentModel.PROP_CREATOR, "Barack Obama");
   //nodeService.setProperty(nodo, ContentModel.PROP_MODIFIER, "Michael Jackson");
       }
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍

In the webscript I do this - look that I one of the attributes in the parameters is "cm:modifier" -


  public static String pruebaChangeOwner () throws Exception
     {
        String strParams="{\"prop_cm_name\":\"pruebaREAL\",\"prop_cm_title\":\"JOJO\",\"prop_cm_modifier\":\"danone\",\"prop_mimetype\":\"application/pdf\",\"prop_cm_author\":\"aaaaa\",\"prop_cm_taggable\":\"\"}";
        String result=executePOST (cookieStore, "http://localhost:8080/share/proxy/alfresco/api/node/workspace/SpacesStore/85118fe0-c681-4d61-9f3f-3f4311315499/formprocessor", strParams,"application/json");
        System.out.println(result);
        return result;
     }
     private static String executePOST (CookieStore cookieStore, String url, String parametros, String strContentType) throws Exception  
     {
      try
      {
         DefaultHttpClient client = new DefaultHttpClient();
         client.setCookieStore(cookieStore);
         HttpPost post = new HttpPost(url);
         post.setHeader("Content-Type", strContentType);
         post.setEntity(new StringEntity(parametros,"UTF-8"));
         ResponseHandler<String> responseHandler = new BasicResponseHandler();
         String response = client.execute(post, responseHandler);
         return response;
      }
      catch (ClientProtocolException ex){return ex.getMessage();}
      catch (IOException ex){return ex.getMessage();}
      catch (Exception ex){return ex.getMessage();}
   }//execute
     
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It updates all atributes but "cm:modifier" is not updated. This is the result printed in console:


{
    
    "persistedObject": "workspace://SpacesStore/85118fe0-c681-4d61-9f3f-3f4311315499",
    "message": "Successfully persisted form for item [node]workspace/SpacesStore/85118fe0-c681-4d61-9f3f-3f4311315499"
}
‍‍‍‍‍‍‍

I have tried also with cmis and it doesn´t work anyway. So I think that maybe I have to try to pass
the values somehow to the behavior in order to let him write them. But the webscript doesn´t take it!

You can try to customize your own webscript ,and in your webscript.
First disable auditable aspect


policyBehaviourFilter.disableBehaviour(nodeRef, ContentModel.ASPECT_AUDITABLE);
‍‍‍

Then update cm:modifier、cm:createor properties
At last enable auditable aspect
policyBehaviourFilter.enableBehaviour(nodeRef, ContentModel.ASPECT_AUDITABLE);
