//**************************************
// Name: Create in memory PDF documents in ASP.NET using Apache NFOP
// Description:The sample demonstrates how to create PDF documents in memory using the open source Apache NFOP([url]http://sourceforge.net/projects/nfop/[/url]) and stream the same to browser instead of saving the PDF documents to harddrive.
// By: Azeet Chebrolu
//
//
// Inputs:Path to your XML Data File and Path to the XSLT Transformation file.
//
// Returns:None
//
//Assumes:Add reference to ApacheFop.Net.dll and vJsLib.dll which comes with Visual J#.net
//
//Side Effects:None
