Thank Sudipto for the link.
Experts,
I used the API as suggested in the first link and managed to iterate through the attachments attached in a process instance but when i am trying to read the attachments using the getInputStream() its returning null, all the other properties of the taskattachment returns correct information. Is this a known bug?? The sample code snippet is as below:
List attach= task.getAttachment();
int i=0;
for (Object obj :attach){
i=i+1;
AttachmentType taskAttachment = (AttachmentType)obj;
System.out.println("Task Attachment " + i + " " + taskAttachment.getName());
System.out.println(taskAttachment.getMimeType());
System.out.println(taskAttachment.getSize());
InputStream inpStream= taskAttachment.getInputStream();
if (inpStream == null){
System.out.println("Stream is empty");
}
