Question

I am using Ektorp (Java API for CouchDB) to store documents in my CouchDB instance. I am having trouble attaching images to documents. Every time I call createAttachment() it throws an ClientProtocolException.

Code Sample:

AttachmentInputStream attachment =
    new AttachmentInputStream(attachmentId,
                              fileInputStream,
                              contentType,
                              file.length());
String rev = db.createAttachment(doc.getId(), attachment));

Does anyone know what’s going wrong?

Answer 1

I had a similar problem using Ektorp. I resolved the issue by passing the latest revision number into the overloaded createAttachment method (db.createAttachment(doc.getId(), doc.getRevision(), attachment))). You could probably do the following:

AttachmentInputStream attachment = 
  new AttachmentInputStream(attachmentId, 
                            fileInputStream, 
                            contentType, 
                            file.length());
String rev = db.createAttachment(doc.getId(), doc.getRevision(), attachment));

Good luck!
