Hi,
I think the problem lies in retrieval.
your node addition code creates the following node structure
root <-- attachment <-- 'filename' --- prop-'jcr:data'
when you retrieve you check for
root <-- attachment --- prop-'jcr:data'
Solution:
fileNode = sourceNode.getNode(<FileName>);
fileNode.getProperty("jcr:data").getStream();
Hope this solves the problem
regards
