[Fwd: Re: creating custom node types inheriting from nt:folder using jcr mapping]

[Ruchi Goel]

Thanks. Please find attached model classes . I do not have  a clearly
isolated unit test case, since I have created a netbeans project where I
am using this.
But these are the two functionalities I am trying to achieve :

 public void testSaveFolder(FolderModelService folderService){
   
    //Test Save  

    //insert an Ad in repository
     Folder folder = new Folder();
     folder.setPath("/cms/folder2");  
     Collection content = new ArrayList();
     content.add(new Folder("subfolder2"));
     folder.setChildren(content);
     folderService.saveFolder(folder);
   
       
    }
 public void testReadFolder(FolderModelService folderService){
       Folder folder =  (Folder)folderService.getFolder("/cms/folder2");
       System.out.print("folder Info : " + folder.getCreationDate());
    }



Thanks,
Ruchi

Hi Ruchi,

I just commited a new unit test. it contains a mapping for nt:folder & nt:file.
This is the first draft :-) . I'm going to work on it. I will add more
unit tests.
See the mapping file : jcrmapping-jcrnodetypes.xml
See the unit test : PersistenceManagerJcrNodeTypeTest

The current ocm implementation forces to use an extra class for the
jcr:resource.
This should be nice to map directly into the file class attributes.

Let me know if you need more help

br,
Christophe

Thanks I will try this. This requires new updated source code , right.
So, I need to checkout the entire graffito source and build the jcr
mapping layer.
