I tried to find 'SimpleTextExtractingPdfContentStreamProcessor' class(or
Interface) in iText documentation API, but i could not find. Can you give me
a fully qualified name? You also mentioned about a zip file. I looked into
that file too, but i could not see any zip file as 'attachement'. For your
reference i had pasted that link here...
