Hi Harshini, I though you were using a large XML String (/Character-Array) with a CharArrayReader to setup your InputSource. Maybe I was wrong? How do you create your input source? It seems that "someone" uses and closes the InputSource (i.e. the stream) before FOP is invoked? Things are still a bit unclear for me. ;-) Could you please tell me, what you are doing before FOP is invoked and what is done afterwards?
