My Code is:

            HttpClient client = new HttpClient();
            GetMethod mGet = new GetMethod(urlString);

            int status = client.executeMethod(mGet);
            System.out.println("client.execute: " + status + "\r\n" + mGet.getResponseBodyAsString());

            StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
            ResultSet rs = searchService.query(storeRef, SearchService.LANGUAGE_XPATH, "/app:company_home");

            try {
                if (rs.length() == 0) {
                    throw new AlfrescoRuntimeException("Didn't find Company Home");
                }
                companyHomeNodeRef = rs.getNodeRef(0);
            } finally {
                rs.close();
            }
            return companyHomeNodeRef.getId().toString();
        }

Someone, can help me? Thanks!

Hi,

You are using the wrong name for the nodelocator. There should be no underscore in the name. Try again with this URL:

<java>
String urlString = "http://127.0.0.1:8080/alfresco/service/api/nodelocator/companyhome?alf_ticket=" + authTicket;
</java>

You can find all registered nodelocators by looking into the context file node-locator-context.xml which is located in webapps/alfresco/WEB-INF/classes/alfresco and then opening the Java class that is registered in the various beans (if you have the sourcecode available). Of course there is also documentation on the wiki and in Docs:

Thanks!

I used this code and worked fine:

public String buscaParent() {

        RepositoryServiceSoapBindingStub repositoryService = WebServiceFactory.getRepositoryService();
        try {
            Store spacesStore = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
            String luceneQuery = "PATH:\"/app:company_home\"";
            Query query = new Query(Constants.QUERY_LANG_LUCENE, luceneQuery);
            QueryResult queryResult = repositoryService.query(spacesStore, query, false);
            ResultSet resultSet = queryResult.getResultSet();
            ResultSetRow[] results = resultSet.getRows();

            for (ResultSetRow resultRow : results) {
                ResultSetRowNode nodeResult = resultRow.getNode();
                idCompanyHome = nodeResult.getId();
            }
        } catch (RemoteException e) {
            adicionaTextoLog("Erro de busca: " + e.getMessage().toString());
        }
        return idCompanyHome;
    }

I hope what help anyone in the future…
