Hi radeya,
you may think of attaching a debug shot of the runtime for that code.
Is that an export method instead?
For example, you can retrieve the node UUID and use the download contents API (/d/a) in order to populate webpages with urls.

Here some suggestions:

Use the Code snippet in the forum to show your source code;

Use MimetypesFileTypeMap to manage all the content types via properties: mime.types in your META-INF folder;

I think that we need some stacktrace to suggest you a possible solution.

Hope this helps.

Hi OpenPj and Sisao,
Thanks for your valuable time.
Actually i'm new to alfresco and i really dont have any idea how this code works. I got this code in forum.
The problem i'm having is i'm not able to get the error messages. I can only catch the exception but i dont have required jars to find out what kind of exception i'm getting so that i can handle. All i can tell you is in which line i'm getting this error while downloading.

DownloadFileAction.java
Content[] readResult = contentService.read(new Predicate(new Reference[]{contentReference}, storeRef, null), Constants.PROP_CONTENT);

According to me the problem must be in UploadFileAction.java, coz i'm able to a download file which is uploaded through Alfresco web client. Please tell me what i'm doing wrong while uploading.

Thanks again
Radheya

Usually to upload a file using Alfresco Web Service Client you can use the following code:


WebServiceFactory.setEndpointAddress(ALFRESCO_WS_API_URL);
      AuthenticationUtils.startSession(ADMIN_USERNAME, ADMIN_PASSWORD);
      String mimeType = new MimetypesFileTypeMap().getContentType(file.getNameWithExtension());
      ContentFormat contentFormat = new ContentFormat(mimeType,"UTF-8");
      Reference reference = new Reference(ConstantsAlfresco.STORE, null, yourFullPathOfTheContent);
      NamedValue[] properties = createProperties(yourUploadFormBean); //create all the custom properties for your content from your form
      ParentReference parentRef = new ParentReference();
      parentRef.setStore(store);
      parentRef.setUuid(reference.getUuid());
      parentRef.setPath(reference.getPath());
      parentRef.setAssociationType(Constants.ASSOC_CONTAINS);
      parentRef.setChildName(Constants.ASSOC_CONTAINS);
      
      CMLCreate create = new CMLCreate();
      create.setParent(parentRef);
      create.setProperty(properties);
      create.setType(yourCustomContentType);   

      CML cml = new CML();
      cml.setCreate(new CMLCreate[] {create});
        
        UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml);
        
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
      int c;
      while ((c = form.getFile().getStream().read()) != -1) {
         stream.write((char) c);
      }
      
      Reference contentNode = result[0].getDestination();
      Content content = WebServiceFactory.getContentService().write(contentNode,
            Constants.PROP_CONTENT, stream.toByteArray(), contentFormat);
      
      if (content == null) 
         throw new RemoteException("Error during storing file");

Hi All,

I have tried using the Code given here but still I am facing the problem. Suggestions for fixing the problem will be helpful.

The code snippet I have used for upload is

 /** Admin user name and password used to connect to the repository */
    protected static final String USERNAME = "admin";
    protected static final String PASSWORD = "admin";
    
    /** The store used throughout the samples */
    protected static final Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
    
    protected static final Reference SAMPLE_FOLDER = new Reference(STORE, null, "/app:company_home/cm:sample_folder9"); 
    
    public static void main(String args[]) throws Exception
    {
       WebServiceFactory.setEndpointAddress("http://localhost:8080/alfresco/api");
        AuthenticationUtils.startSession(USERNAME, PASSWORD);
        try
        {
            // Check to see if the sample folder has already been created or not
            WebServiceFactory.getRepositoryService().get(new Predicate(new Reference[]{SAMPLE_FOLDER}, STORE, null));
            ParentReference parentRef = new ParentReference();
            parentRef.setStore(STORE);
            parentRef.setUuid(SAMPLE_FOLDER.getUuid());
            parentRef.setPath(SAMPLE_FOLDER.getPath());
            parentRef.setAssociationType(Constants.ASSOC_CONTAINS);
            parentRef.setChildName(Constants.ASSOC_CONTAINS);
            
            NamedValue[] properties2 = new NamedValue[]{Utils.createNamedValue(Constants.PROP_NAME, "SampleContent1.txt")};
            CMLCreate create2 = new CMLCreate();
            create2.setParent(parentRef);
            create2.setProperty(properties2);
            create2.setType(Constants.TYPE_CONTENT);   

            CML cml2 = new CML();
            cml2.setCreate(new CMLCreate[] {create2});
              
              UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml2);
              
            Reference contentNode = result[0].getDestination();
            ContentFormat format = new ContentFormat(Constants.MIMETYPE_TEXT_PLAIN, "UTF-8");
            byte[] content = "This is some test content provided by the Alfresco development team!".getBytes();
            Content content1 = WebServiceFactory.getContentService().write(contentNode,
