How to send dam asset rendition as an attachment in email

[HarishDv]

Hi ,

I am trying to send a DAM Asset rendition as an attachment via mail.

I am sending mails using org.apache.commons.mail.HtmlEmail package.

If i use the below code

EmailAttachment attachment = new EmailAttachment();

attachment.setURL(new URL("http://localhost:4502/content/dam/geometrixx/new.jpg");
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription(assetName);
attachment.setName(assetName);

email.attach(attachment);

i am getting the error org.apache.sling.auth.core.impl.SlingAuthenticator getAnonymousResolver: Anonymous access not allowed by configuration - requesting credentials

If i use

File assetRendition = asset.adaptTo(File.class);
DataSource datasource = new FileDataSource(assetRendition);

 email.attach(datasource,"Image Name","Image Desc");

I am getting null pointer exception.

If anyone has already used , please let me know how to resolve this.

Thanks in advance

If you already have the Asset object, something like this should work:

Asset asset = // get asset Rendition rendition = // get rendition InputStream stream = rendition.getStream(); String mimeType = rendition.getMimeType() DataSource ds = new ByteArrayDataSource(stream, mimeType); email.attach(ds, "Image Name", "Image Desc");

I am working on Java code that uploads a file to CQ and saves the file to the CQ DAM. I am using a Sling Servlet and the JCR API to create app logic to save a file to the DAM. However - you still have to authenticate  using the JCR API from within a bundle. For example:  

 private String writeToDam(InputStream is, String fileName)

{
try
{
    session = this.repository.loginAdministrative(null);
    Node node = session.getNode("/content/dam/travel");  
    javax.jcr.ValueFactory valueFactory = session.getValueFactory();             
    javax.jcr.Binary contentValue = valueFactory.createBinary(is);            
    Node fileNode = node.addNode(fileName, "nt:file"); 
    fileNode.addMixin("mix:referenceable"); 
    Node resNode = fileNode.addNode("jcr:content", "nt:resource"); 
    resNode.setProperty("jcr:mimeType", "image/jpeg"); 
    resNode.setProperty("jcr:data", contentValue); 
    Calendar lastModified = Calendar.getInstance(); 
    lastModified.setTimeInMillis(lastModified.getTimeInMillis()); 
    resNode.setProperty("jcr:lastModified", lastModified); 
    session.save();            
     
     
    // Return the path to the document that was stored in CRX. 
    return fileNode.getPath();
}

So for your workflow -- instead of writing a file to the DAM, you want to read a file from the DAM. You still have to authenticate.
