I Get Error NullPointerException When Use NodeService

[geyson_santana]

My code:

79            ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);
80            NodeService nodeService = serviceRegistry.getNodeService();
81           
82            NodeRef nodeRef = new NodeRef("workspace://SpacesStore/" + IdNode);
83            System.out.println("Node: "+nodeRef.getId());
84            QName CUSTOM_ASPECT_QNAME = QName.createQName("custom.model", "tipo_documento");
85            nodeService.setProperty(nodeRef, CUSTOM_ASPECT_QNAME, propertyOne);

I get(in line 79):

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
   at Telas.SubMenuNovo.adicionaPropriedades(SubMenuNovo.java:79)

I want set up properties in a document with custom metadata with my application. The custom metadata just work at interface Alfresco Explorer. The line 83 prints ok the IDnode(Node of the document).  Anyone help me? Thanks!

From the error it seems that either ServiceRegistry or beanFactory is coming with null value.

I solved my problem using the code:

public void adicionaPropriedades(String node, String value) throws RemoteException {
        try {
            Store spacesStore = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
            //create the node reference
            Reference reference = new Reference(spacesStore, node, null);
            //create the predicate
            Predicate predicate = new Predicate();
            predicate.setNodes(new Reference[]{reference});
           
            QName PROP_QNAME_MY_PROPERTY_TIPO = QName.createQName("custom.model", "tipo_documento");
            QName PROP_QNAME_MY_PROPERTY_NUMERO = QName.createQName("custom.model", "numero");
           
            NamedValue[] propriedades = new NamedValue[2];
            propriedades[0] = Utils.createNamedValue(PROP_QNAME_MY_PROPERTY_TIPO.toString(), value);
            propriedades[1] = Utils.createNamedValue(PROP_QNAME_MY_PROPERTY_NUMERO.toString(), value);
            System.out.println("Constants: "+Constants.PROP_DESCRIPTION);
           
            CMLUpdate update = new CMLUpdate();
            update.setWhere(predicate);
            update.setProperty(propriedades);
           
            CML cmlUpdate = new CML();
            cmlUpdate.setUpdate(new CMLUpdate[]{update});
            //perform a CML update
            WebServiceFactory.getRepositoryService().update(cmlUpdate);
           
        } catch (InvalidNodeRefException e) {
            System.out.println("Erro: " + e);
        }
    }

Thanks for all or nothing.
