Hi All, I'm writing a transformation connector to extract low level features from images. First I used that connector without tika extractor and I worked fine. But when I used it with Tika connector (after tika) if fails to extract features. After debugging I found out that the stream is empty after tika transformation. Actually inside tika connector, it creates a new in memory or file stream output, but original input stream is never copied to it. Connector should reset binary stream after utilizing the stream to get metadata so the original inputstream is available from connector to connector.
Here I have attached a simple solution of stream copy and reset that worked for me. Thanks, Chalitha -- J.M Chalitha Udara Perera *Department of Computer Science and Engineering,* *University of Moratuwa,* *Sri Lanka*
