      Map<String, String> params = new HashMap<String, String>();

      params.put(SessionParameter.USER, username);

      params.put(SessionParameter.PASSWORD, password);

Thanks for your reply.
I have tried your suggestion.It is work for me.But i get some other exception.I am using alfresco community edition 4.0d.
Can you just check mu code and tell me where i made mistake?
MY code is:
<code>
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/service/cmis";
         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());

      }

I have ran your code and didn't get any error.I use version 4.2.c ,I think maybe it's a bug of 4.0.d.
