Hello,
I am using alfresco 4.0.2 enterprise, I found an example webscript for uploading a file, it uses reference of DataDictionaryHelper class but I don't know its package name and its jar file also my IDE (Netbeans 7.2) couldn't able to give me suggestion. Could anyone tell me how can I import DataDictionaryHelper class? My code is


public class UploadWebScript extends DeclarativeWebScript {

   private static Log log = LogFactory.getLog(UploadWebScript.class);
  
   private NodeService nodeService;
   private ContentService contentService;
   private TransactionService transactionService;
   private DataDictionaryHelper dataDictionaryHelper;
   private MimetypeService mimetypeService;
   
    public void setNodeService(NodeService nodeService) {
        this.nodeService = nodeService;
    }
  
   public void setContentService(ContentService contentService) {
      this.contentService = contentService;
   }

   public void setTransactionService(TransactionService transactionService) {
      this.transactionService = transactionService;
   }

   public void setDataDictionaryHelper(DataDictionaryHelper dataDictionaryHelper) {
      this.dataDictionaryHelper = dataDictionaryHelper;
   }
   
    public void setMimetypeService(MimetypeService mimetypeService) {
        this.mimetypeService = mimetypeService;
    }
   
    @Override
    protected Map<String, Object> executeImpl(WebScriptRequest req, Status status) {
       I18NUtil.setLocale(Locale.ENGLISH);
   Map<String, Object> model = new HashMap<String, Object>();
       UserTransaction tx = transactionService.getUserTransaction(false);
       try {
         tx.begin();
           NodeRef newNode = createNewNode(req);
         tx.commit();
           model.put("newNode", newNode);
       } catch (RollbackException e) {
         log.warn(e);
         status.setCode(500);
         status.setMessage(e.getLocalizedMessage());
         status.setException(e);
         status.setRedirect(true);
      } catch (Exception e) {
         log.warn(e);
         status.setCode(500);
         status.setMessage(e.getLocalizedMessage());
         status.setException(e);
         status.setRedirect(true);
         try {
            tx.rollback();
         } catch (Exception e1) {
            log.error("Transaction rollback failed");
            log.error(e1);
         }
      }
      return model;
    }

   private NodeRef createNewNode(WebScriptRequest req) {
           if (log.isDebugEnabled()) {
         log.debug("Creating new node of type '" + req.getParameter("type") + "' under node " + req.getParameter("uuid"));
      }

        Map<String, String> params = getRequestParametersAsMap(req);
        Map<QName, Serializable> properties = dataDictionaryHelper.convertParametersToProperties(params);
        NodeRef parent = new NodeRef(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE, req.getParameter("uuid"));
       
        QName contentTypeQname = QName.createQName(YOUR_CUSTOM_NAMESPACE, req.getParameter("type"));

        FormData fd = (FormData) req.parseContent();
        FormField[] fields = fd.getFields();
        for (FormField field : fields) {
           if (field.getIsFile()) {
             String name = field.getFilename();
               properties.put(ContentModel.PROP_NAME, name);
               ChildAssociationRef children = nodeService.createNode(parent, ContentModel.ASSOC_CONTAINS,
                     DataDictionaryHelper.getAssocNameFromFileName(name), contentTypeQname, properties);
               NodeRef newNode = children.getChildRef();
            
              ContentWriter writer = contentService.getWriter(newNode, ContentModel.PROP_CONTENT, true);
              writer.setMimetype(mimetypeService.guessMimetype(name));
              writer.putContent(field.getInputStream());
              return newNode;
         }
        }
        log.warn("Request did not have a file");
        return null;
   }

   private Map<String, String> getRequestParametersAsMap(WebScriptRequest req) {
      Map<String, String> params = new HashMap<String, String>();
      for (String name : req.getParameterNames()) {
         params.put(name, req.getParameter(name));
      }
      return params;
   }
}
