Hi jnorris,
Human Task by default support attachment,
here you go
Attachment attachment = new Attachment();
attachment.setAccessType(AccessType.Inline);
attachment.setAttachedAt(new java.util.Date());
attachment.setAttachedBy(new User(userLogon));
attachment.setContentType("image");
attachment.setName("myTaskAttachment");
attachment.setSize(20000);
// file is a byte[] variable
Content content = new Content(file);
attachment.setContent(content);
TaskClient taskClient = getTaskClient();
BlockingAddAttachmentResponseHandler responseHandler = new BlockingAddAttachmentResponseHandler();
taskClient.addAttachment(taskId, attachment, content, responseHandler);
Map<String, Long> result = new HashMap<String, Long>(2);
result.put("attachmentId", responseHandler.getAttachmentId());
result.put("contentId", responseHandler.getContentId());
Regards,
