Re: [java ee programming] fop.getDefaultHandler());

Hi Chil-Hoan,

Thank you very much for your detailed response.

My problem was with fop jar. I have updated it. Now I create PDF but it is empty...

I get following exception (I marked it).

The exception refers to FopFactory fopFactory = FopFactory.newInstance();

Below exception I also enclose code with the method that creates PDF.

Thanks in advance for help!

Regards,

Rafal

==================

CODE:

BufferedOutputStream out =

new BufferedOutputStream(new FileOutputStream(new File("C:/PDFfile.pdf")));

Document doc;

String employeeNr;

// Creating FO

ByteArrayOutputStream tmpUt =

new ByteArrayOutputStream();

tmpUt.close();

// Using FOP to convert temporary file to PDF

byte[] fo = tmpUt.toByteArray();

InputStream bais =

new ByteArrayInputStream(fo);

FopFactory fopFactory = FopFactory.newInstance(); //HERE IS THE PROBLEM NOW

try{

Fop fop = fopFactory.newFop(MimeConstants.

MIME_PDF,out);

TransformerFactory factory = TransformerFactory.newInstance();

Transformer transformer = factory.newTransformer();

Logger foLogger = Logger.getLogger(

"org.apache.fop");

foLogger.setLevel(Level.

SEVERE);

Source src = "">

new StreamSource(bais);

Result res =

new SAXResult(fop.getDefaultHandler());

transformer.transform(src, res);

}

finally{

out.close();

}

Hi Rafal,

Do you write XML and fo:XSL files to generate PDF format?

Why do you getDefaultHandler??

I am writing simple steps for you:

1. Create XML file and Save it at specific location.

2. Create fo:XLS fils and Save it at specific location.

3. Create Java file.

- Set up a FOP driver

Driver driver = new Driver();

- Set up the logger for the driver

Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_INFO)

driver.setLogger(logger)

- Declare Render format

driver.setRenderer(Driver.RENDER_PDF)

- invoke xml file and xsl file and put them into Handler

XSLTInputHandler inputHandler = new XSLTInputHandler(xmlfile, xslFile)

- Declare ByteSteream and read them byte

ByteArrayOutPutStream outStream = new ByteArryaOutPutStream()

driver.setOutputStream(outStream)

driver.render(inputHandler.getParser(),inputHandler.getInputSource())

byte[] content = outStream.toByteArray();

- Display PDF

response.setContentLength(content.length)

response.setContentType("application/pdf")

response.setHeader(" something.....")

response.getoutputStream().write(content);

response.getOutputSteram().flush()

This is simple explanation (Web Based application) to implement PDF document using xml and fo:XSL.

This will give you some idea how to write in Java.

Good Luck!!!!

Chil

Hi,

Can sobmbody advise me please why by fop.getDefaultHandler()) I get error: The method getDefaultHandler() is undefined for the type Fop.

Thanks for help!
