Hi,

I assume you are developing a stand-alone Alfresco client. Try using CMIS and OpenCMIS library for this instead, it will give you a standard approach, hiding some of the details:

Here is an example on how to upload a file and set a type at the same time:


public Document createDocumentFromFileWithCustomType(Session session) {
        String documentName = "somefile.pdf";
        File file = new File("/home/martin/Documents/somefile.pdf");
        Folder parentFolder = session.getRootFolder();

        // Check if document already exist, if not create it
        Document newDocument = (Document) getObject(session, parentFolder, documentName);
        if (newDocument == null) {
            // Setup document metadata
            Map<String, Object> newDocumentProps = new HashMap<String, Object>();
            newDocumentProps.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
            newDocumentProps.put(PropertyIds.NAME, documentName);

            InputStream is = null;
            try {
                // Setup document content
                is = new FileInputStream(file);
                String mimetype = "application/pdf";
                ContentStream contentStream = session.getObjectFactory().createContentStream(
                        documentName, file.length(), mimetype, is);

                // Create versioned document object
                newDocument = parentFolder.createDocument(newDocumentProps, contentStream, VersioningState.MAJOR);
                logger.info("Created new document: " + getDocumentPath(newDocument) +
                    " [version=" + newDocument.getVersionLabel() + "][creator=" + newDocument.getCreatedBy() +
                    "][created=" + date2String(newDocument.getCreationDate().getTime()) + "]");

                // Close the stream to handle any IO Exception
                is.close();
            } catch (IOException ioe) {
                ioe.printStackTrace();
            } finally {
                IOUtils.closeQuietly(is);
            }
        } else {
            logger.info("Document already exist: " + getDocumentPath(newDocument));
        }

        return newDocument;
    }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In this case we set the generic/base CMIS type that corresponds to cm:content.
Note also that the document is created in the Root folder of Alfresco (i.e. Company Home).

How to create a session:


    public Session getSession(String connectionName, String username, String pwd) {
        Session session = connections.get(connectionName);
        if (session == null) {
            logger.info("Not connected, creating new connection to Alfresco with the connection id ("
                    + connectionName + ")");

            // No connection to Alfresco available, create a new one
            SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
            Map<String, String> parameters = new HashMap<String, String>();
            parameters.put(SessionParameter.USER, username);
            parameters.put(SessionParameter.PASSWORD, pwd);
            parameters.put(SessionParameter.ATOMPUB_URL,
                    "http://localhost:8080/alfresco/api/-default-/cmis/versions/1.1/atom");
            parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
            parameters.put(SessionParameter.COMPRESSION, "true");
            parameters.put(SessionParameter.CACHE_TTL_OBJECTS, "0");

            // If there is only one repository exposed (e.g. Alfresco), these
            // lines will help detect it and its ID
            List<Repository> repositories = sessionFactory.getRepositories(parameters);
            Repository alfrescoRepository = null;
            if (repositories != null && repositories.size() > 0) {
                logger.info("Found (" + repositories.size() + ") Alfresco repositories");
                alfrescoRepository = repositories.get(0);
                logger.info("Info about the first Alfresco repo [ID=" + alfrescoRepository.getId() +
                        "][name=" + alfrescoRepository.getName() +
                        "][CMIS ver supported=" + alfrescoRepository.getCmisVersionSupported() + "]");
            } else {
                throw new CmisConnectionException(
                        "Could not connect to the Alfresco Server, no repository found!");
            }

            // Create a new session with the Alfresco repository
            session = alfrescoRepository.createSession();

            // Save connection for reuse
            connections.put(connectionName, session);
        } else {
            logger.info("Already connected to Alfresco with the connection id (" + connectionName + ")");
        }

        return session;
    }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And the getObject method:


  private CmisObject getObject(Session session, Folder parentFolder, String objectName) {
        CmisObject object = null;

        try {
            String path2Object = parentFolder.getPath();
            if (!path2Object.endsWith("/")) {
                path2Object += "/";
            }
            path2Object += objectName;
            object = session.getObjectByPath(path2Object);
        } catch (CmisObjectNotFoundException nfe0) {
            // Nothing to do, object does not exist
        }

        return object;
    }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi,

The error clearly says, the site "HULA" doesn't exists, you can create a new site with same name, or you can give an existing siteid, as well as you have to create "/facultativos" under the newly created site, rest alfresco will do.
