Error while using the XMLP API to generate a report

Question

Hi all,
I am trying to generate a report using stand-alone application by the JAVA API (User doc Ch 11). I am using RFT template for this.
Step1: Create XSL from RTF file. I could do this. Example is given in page 262 of the guide. Here is the code snippet (all import, try/catch removed):
RTFProcessor rtfProcessor = new RTFProcessor(args[0]);
rtfProcessor.setOutput(args[1]); // output file
rtfProcessor.process();
This generated a XSL file correctly.
Step 2: Using the XSL and XML file, it could generate a output. This is failing for me. (Page 265). Code snippet below:
<snippet>
FOProcessor processor = new FOProcessor();
processor.setData(args[0]); // set XML input file
processor.setTemplate(args[1]); // set XSL input file
processor.setOutput(args[2]); //set output file
processor.setOutputFormat(FOProcessor.FORMAT_PDF);
// Start processing
try
processor.generate();
catch (XDOException e)
e.printStackTrace();
System.exit(1);
System.exit(0);
</snippet>
It compiles. When I run this program (class), I get the following errors and I do not know where to look for help/resolution:

Hi Tim,
My present requirement is :
In OAF page, When i click "generate" button, it should generate pdf which is XML publisher output.
My code is able to generate pdf/excel file with zero bytes and also i'm unable to open this pdf file. Following code i have written in processFormRequest:
I debugged this code . it's working fine till processor.setOutputFormat(FOProcessor.FORMAT_EXCEL); It's unable to execute the FO processor Engine.
Kindly please help me to rectify this error.
if (pageContext.getParameter ("GeneratePDF")!= null)
try{  
RTFProcessor rtf = new RTFProcessor("C:\\cash_receipt\\CASH_RECEIPT_XML5.rtf");
System.out.println(" step -2");
rtf.setOutput("C:\\cash_receipt\\CASH_RECEIPT_XML7.xsl"); // set output AS XSL FILE
System.out.println(" step -1");
Document dc = rtf.process();
System.out.println(" rtf.process()" + dc.toString());
FOProcessor processor = new FOProcessor();
// set the data definition
processor.setData("C:\\cash_receipt\\cash_receipt_xml5.xml");
System.out.println(" step 1");
//("C:\\cash_receipt\\cash_receipt_xml5.xml");
// set the template
processor.setTemplate("C:\\cash_receipt\\CASH_RECEIPT_XML7.xsl");
System.out.println(" step 2");
//("C:\\cash_receipt\\CASH_RECEIPT_XML5.xsl");
//Set the output file and the output format for a PDF document:
processor.setOutput("C:\\TestXML.Excel");
System.out.println(" step 3");
processor.setOutputFormat(FOProcessor.FORMAT_EXCEL);
// run the FO processor Engine
System.out.println(" step 4");
processor.generate();
System.out.println(" step 5");
catch (Exception e) {
e.printStackTrace();
System.out.println("XDOException " + e.getMessage());
thanks,
Keshav
