creating custom node types inheriting from nt:folder using jcr mapping

[Ruchi Goel]

Hi,
 I want to use jcr mapping layer for creating custom node type "folder"
which should inherit from "nt:folder"

I have following custom_nodetype.xml
<nodeTypes xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
   xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:rep="internal"
   xmlns:mix="http://www.jcp.org/jcr/mix/1.0">
    <nodeType name="folder" isMixin="false"
hasOrderableChildNodes="false" primaryItemName="">
   <supertypes>
     <supertype>nt:folder</supertype>
   </supertypes>    </nodeType>

</nodeTypes>


I have following jcrmapping descriptor

<class-descriptor className="com.sun.portal.cms.model.HeirarchyContent"
jcrNodeType="nt:hierarchyNode" discriminator="false" >
<!-- Field-descriptor is used to map simple attributes to jcr property -->
   <field-descriptor fieldName="path" path="true" />
   <field-descriptor fieldName="creationDate" jcrName="jcr:created" />
/>
</class-descriptor>

<class-descriptor className="com.sun.portal.cms.model.Folder"
jcrNodeType="folder"
extend="com.sun.portal.cms.model.HeirarchyContent"  discriminator="false" >
<!-- Field-descriptor is used to map simple attributes to jcr property -->
<field-descriptor fieldName="path" path="true" />
/>
<collection-descriptor fieldName="children" proxy="false"
jcrNodeType="nt:hierarchyNode"
                             
elementClassName="com.sun.portal.cms.model.HeirarchyContent"
                             
collectionConverter="org.apache.portals.graffito.jcr.persistence.collectionconverter.impl.NTCollectionConverterImpl"
/>
</class-descriptor>



The problem is I am able to retrieve the items which are properties but
I do not see any child node definitions in folder. Ideally since folder
is inheriting from nt:folder , it should  get a childnode definition of
type nt:heirrarchynodeType

Is there anything I am missing ?
Checked out PersistenceAutoTest.java but it uses all custom nodetypes
which are inherited from nt:base and so , it has childnodedefintions in
custom node type definition.

Help appreciated.
Thanks,
Ruchi

Hi Ruchi,

It seems to be ok. Send me your unit tests and you model classes.
It is a good exemple to add and I will have time to help you this afternoon.

Christophe

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
