Registering Custom Model Again

[thaneshk]

Hi,

I have got this method from DictionaryDAOTest

 NamespaceDAO namespaceDAO = new NamespaceDAOImpl();
                    DictionaryDAOImpl dictionaryDAO = new DictionaryDAOImpl(namespaceDAO);
                    
                    DictionaryBootstrap bootstrap = new DictionaryBootstrap();
                    List<String> bootstrapModels = new ArrayList<String>();
                    
                    bootstrapModels.add("alfresco/model/dictionaryModel.xml");
                    bootstrapModels.add("alfresco/model/systemModel.xml");
                    bootstrapModels.add("alfresco/model/contentModel.xml");
                    bootstrapModels.add("alfresco/model/applicationModel.xml");
                    bootstrapModels.add("alfresco/extension/customModel.xml");                
                    
                    bootstrap.setModels(bootstrapModels);
                    bootstrap.setDictionaryDAO(dictionaryDAO);
                    bootstrap.bootstrap(); 

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And i add a new property to my customModel and run this method again. But when i try to set the value for my new property i get java.null pointer exception

Do i need to run anything else after i re-register the models.

Please let me know. Urgent help.

Thank you.

Here's some code that registers a new model programmatically and then uses the model via the JCR API.

package org.alfresco.repo.dictionary;

import javax.jcr.Node;
import javax.jcr.Repository;
import javax.jcr.Session;
import javax.jcr.SimpleCredentials;

import org.alfresco.service.ServiceRegistry;
import org.alfresco.service.cmr.dictionary.DictionaryService;
import org.alfresco.service.cmr.dictionary.TypeDefinition;
import org.alfresco.service.namespace.QName;
import org.alfresco.util.ApplicationContextHelper;
import org.springframework.context.ApplicationContext;

public class RegisterModel
{

   /**
    * @param args
    */
   public static void main(String[] args)
      throws Exception
   {
      // initialise application context
      // Note: the dictionary bootstrap will take during this step
        ApplicationContext ctx = ApplicationContextHelper.getApplicationContext();
        DictionaryService service = (DictionaryService)ctx.getBean(ServiceRegistry.DICTIONARY_SERVICE.getLocalName());

        // retrieve type that does not yet exist via Dictionary Service 
        QName typeName = QName.createQName("newModelURI", "newType");
        TypeDefinition typeDef = service.getType(typeName);
        assert(typeDef == null);
        
        // create new model and new type (this can also be parsed from XML definition)
        M2Model model = M2Model.createModel("newModelPrefix:newModel");
        M2Namespace importD = model.createImport("http://www.alfresco.org/model/dictionary/1.0", "d");
        M2Namespace importSys = model.createImport("http://www.alfresco.org/model/system/1.0", "sys");
        M2Namespace namespace = model.createNamespace("newModelURI", "newModelPrefix");
        M2Type type = model.createType("newModelPrefix:newType");
        type.setParentName("sys:base");
        M2Property prop = type.createProperty("newModelPrefix:newProp");
        prop.setType("d:text");
        
        // register model programmatically (this is currently only possible via the Dictionary DAO)
        DictionaryDAO dao = (DictionaryDAO)ctx.getBean("dictionaryDAO");
        dao.putModel(model);

        // retrieve type that's now been registered programmatically (via Dictionary Service) 
        typeDef = service.getType(typeName);
        assert(typeDef != null);

        // perform simple create of node with new type
        Repository repository = (Repository)ctx.getBean("JCR.Repository");
        Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));
        Node rootNode = session.getRootNode();
        Node newNode = rootNode.addNode("test", "newModelPrefix:newType");
        newNode.setProperty("newModelPrefix:newProp", "dave");
                
        System.out.println(newNode.getProperty("newModelPrefix:newProp").getString());
        System.exit(0);
   }

}

I created new content type which includes the cm:content as parent.and stored the newcontent model under extension folder.here is the code

 <type name="dml:rsscontent"> 
         <title>rsscontent</title> 
         <parent>cm:content</parent> 
         <properties> 
            <property name="rss:title">
               <type>d:text</type>
            </property>
            <property name="rss:description">
               <type>d:text</type>
            </property>
            <property name="rss:link">
               <type>d:text</type>
            </property>
            <property name="rss:author">
               <type>d:text</type>
            </property>            
         </properties>
      </type>
  ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

when i create content through alfresco i am able to select the new content type(i mean rsscontent). content was created and i could view through web client.
when i addnew node through jcr api…. i want to use my new content type(i mean rsscontent) to create a content..here is my java code
Node content = rssFeeds.addNode("dml:" + item.getTitle(),"dml:rsscontent");//Here i am pointing towards my new content type but using this i am not able to create contents.
is there any other properties i need to set?            
is it possible to store the metainformation without adding content using jcr-api?
