Okay this is part of my Servlet:

PDFReportGenerator pConn = new PDFReportGenerator();
			
JSONWriter writer = new JSONWriter();
			
	String[] filePathArray = new String[b13Conn.getBlock13RetroNoteArray().length];
	for(int i = 0; i < b13Conn.getBlock13RetroNoteArray().length; i++){
				
	sConn.setPONumber(gConn.getAs400Conn(), b13Conn.getBlock13RetroNoteArray()[i][0]);
	sConn.setSeatDesc(gConn.getAs400Conn(), b13Conn.getBlock13RetroNoteArray()[i][0]);
				
pConn.set8130ReportRetro(gConn.getAs400Conn(), _8130Type, lServer, sConn.getIYear(), trackingNumber, proudctionAuthorizationNumber, _8130CONumber, _8130TypeOfShipment, b13Conn.getBlock13RetroNoteArray()[i][2], approvedDesignFlag, darName, proudctionAuthorizationNumber, approvalDate, _8130ShipperNumber, "1", sConn.getSeatDesc(), b13Conn.getBlock13RetroNoteArray()[i][1], b13Conn.getBlock13RetroNoteArray()[i][0], "N/A", "1", "INSPECTED", b13Conn.getBlock13RetroNoteArray()[i][0], sConn.getPono());
			
	filePathArray[i] = pConn.getPDFFilePathPage1();
				
}
			
	String PDFFilePath = writer.write(filePathArray);
			
	jReturnString  = "{\"errorString\": \"" + pConn.getErrorString() + "\", \"filePath\": \"" + PDFFilePath + "\"}";
	System.out.println(jReturnString);

The jReturnString looks like this:

{"errorString": "NoError", "filePath": "["\/\/gvas400\/home\/ShippingDocssupport\/Temp\/ShippingDocs\/8130\/2011\/_185049_999999_SSR101911 CO185049_000143689.pdf","\/\/gvas400\/home\/ShippingDocssupport\/Temp\/ShippingDocs\/8130\/2011\/_185049_999999_SSR101911 CO185049_000143690.pdf","\/\/gvas400\/home\/ShippingDocssupport\/Temp\/ShippingDocs\/8130\/2011\/_185049_999999_SSR101911 CO185049_000143691.pdf"]"}

The JSON seems to be modifing the "\\"

Something is preventing my call back function from fireing.

Usually that means that the JSON is invalid.

I see that you are building your JSON by hand. Don't. Let a library such as Google's Gson handle the JSON conversion.
