import org.apache.chemistry.opencmis.commons.enums.BindingType;

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());
      System.out.println(newFolder.getId());

   }
   public static void main(String[] args){
      Test t  = new Test();
      t.createFolder();
   }
}
