What is the best way to list the content of a folder ?

sam69 — Mon, 03 Apr 2006 16:02:35 GMT

Hello !First of all, I am a newbie in the Alfresco WebServices, but I have already read the WebService Samples.I can't really find an example to do this simple task:I want to get all the items (documents and folder) of a specific folder.I tried that : RepositoryServiceSoapBindingStub repositoryServi

"/app:company_home/*[@cm:name=\"" + Data Dictionary + "\"]"

Should find the data dictionary folder (well all folders called DD)

If you want the top level children
"/app:company_home/*[@cm:name=\"" + Data Dictionary + "\"]/*"

If you want all the children
"/app:company_home/*[@cm:name=\"" + Data Dictionary + "\"]//*"

However these queries are not the most efficient.

I would recommend you find the DD node and then run the query in this context with "./*" or ".//*" to find the children or all descendants respectively.

Hi,

Alternativly you ca n use the queryChildren method on the repository web service. This will return all the children of a given reference.

It should be a little faster than the query since it uses the underlying API directly, but does not have the flexability of a query.

Cheers,
Roy

Thaks Andy and rwetherall !

I used both of yours methods 😉 It's work fine when I run this code in a standalone application.

Here is my code if it can help somebody else..

this.authentification.demarrerSession(LOGIN, PASSWORD);

      RepositoryServiceSoapBindingStub repositoryService = WebServiceFactory.getRepositoryService();       
      
      Reference reference = new Reference(new Store(StoreEnum.workspace, "SpacesStore")
          , null, "/app:company_home/*[@cm:name=\"" + NOM_UTILISATEUR_DEPOT_GEDIWEB + "\"]");
      Predicate predicate = new Predicate(new Reference[]{reference}, null, null);        
      Node[] nodes = repositoryService.get(predicate);
      
      // Query pour lister les enfants du noeud Gediweb
      Reference nodeGediweb = nodes[0].getReference();
      String nodeGediwebId = nodeGediweb.getUuid();

      QueryResult rootChildren = WebServiceFactory.getRepositoryService().queryChildren(nodeGediweb);
      ResultSet rootChildrenResults = rootChildren.getResultSet();

      ResultSetRow[] rows = rootChildrenResults.getRows();
      for (int i = 0; i < rows.length; i++)
      { etc….
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But now, I am fighting with tomcat, it seems tomcat use it's own (old) library and I have some exception with security 😞

Hi,
when working this way using the webservices api:
Once you got a ResultSetRowNode, how to get to the actual org.alfresco.webservice.types.Node??
I want to fetch the properties of the node..

another thing is, doing this:


   String np = "/app:company_home/cm:Public_x0020_website/cm:Events";
        Store store = new Store(StoreEnum.workspace, "SpacesStore");
        Reference node = new Reference(store, null, np);
        RepositoryServiceSoapBindingStub repositoryService = WebServiceFactory.getRepositoryService();       
        Predicate predicate = new Predicate(new Reference[]{node}, null, null);
        Node[] nodes = null;
        try {
         nodes = repositoryService.get(predicate);
         …
‍‍‍‍‍‍‍‍‍‍‍

I get an exception that more than one node is found
(Failed to resolve to a single NodeRef with parameters (store=workspacepacesStore uuid=null path=/app:company_home/cmublic_x0020_website/cm:Events/*), found 19 nodes.), what is the logic behind this?
How can I fetch all nodes in a given space and catch their properties?

Thanks,
Tim
