Hello Everyone!

I am using alfresco community edition 4.0d. I have connected alfresco using java Open CMIS.When i create a folder using aspect it will guve me error like prefix can not be null.
Below is my code which i am using for creating a folder.

I have tried both Url:-http://localhost:8080/alfresco/cmisatom,http://localhost:8080/alfresco/service/cmis

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.chemistry.opencmis.commons.PropertyIds;
import org.apache.chemistry.opencmis.commons.SessionParameter;

public class Test 
{

   
      private Session getSession(String serverUrl, String username, String password)
      {
      SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
      Map<String, String> params = new HashMap<String, String>();
      params.put(SessionParameter.USER, username);
      params.put(SessionParameter.PASSWORD, password);
      params.put(SessionParameter.ATOMPUB_URL, serverUrl);
      params.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
      params.put   (SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");         
      List<Repository> repos = sessionFactory.getRepositories(params);
      if (repos.isEmpty()) {
      throw new RuntimeException("Server has no repositories!");
      }
      return repos.get(0).createSession();
      }
public void  createFolder()
      {
         String servalUrl="http://localhost:8080/alfresco/cmisatom";
         String userName="admin";
         String password="admin";
      
         Map<String, Object> properties = new HashMap<String, Object>();
         properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:folder,P:cm:titled");   
         properties.put(PropertyIds.NAME,"TESTFOLDER2");
         properties.put(PropertyIds.CREATED_BY, "admin");
          properties.put("cm:title", "Title");
         properties.put("cm:description", "Desc");
         Session session=getSession(servalUrl, userName, password);
         AlfrescoFolder root=(AlfrescoFolder) session.getRootFolder();
         System.out.println("The Name:"+root.getId()+root.getName());
         AlfrescoFolder newFolder=(AlfrescoFolder) root.createFolder(properties);
         System.out.println(newFolder.getName());
         
      }

May be it is a bug of your version 4.0.d (I use 4.2.d)

[rutaveejshah]

I have tried using Alfresco community Edition 4.2 d still i got this error.
Tell me which jar file are you used for this.
