PDF file creation

[Former Member]

Hi,

I have created a JSPDynpage with a tableview and a button when pressed converts this tableview to pdf file but when I load and try to run this par file I get the following error.

Portal Runtime Error An exception occurred while processing a request for : iView : N/A Component Name : N/A com/lowagie/text/Document. Exception id: 03:57_26/04/05_0130_6435050

Any advice would be appreciated.

Hi NAC,

Put the put the itext-1.2.jar in PORTAL-INF->lib folder. You shouldn't get that error. The reason why you have to do that is because it is external to portal. The library doesn't exist on portal.

Hi,

I am developing in JSPDynpages and am trying to create a PDF file. When I click a button on a page I call the following function.

public void ConvertDefaultTableViewToPDF( IPortalComponentResponse response, IPortalComponentRequest request)

{

try

{

com.lowagie.text.Document document = new com.lowagie.text.Document( PageSize.A4);

HttpServletResponse res = request.getServletResponse(true);

res.setContentType( "application/pdf");

PdfWriter.getInstance( document, res.getOutputStream());

document.open();

document.add(new Paragraph("Hello World"));

document.close();

}

catch( Exception ex)

{

response.write( "ERROR: " + ex);

}

return;

}

but nothing happens instead I get Portal Runtime error. Do I need to add any code on the new page that I am opening for the PDF file to show within.

Any help would be appreciated.

I am sending you a JSPDynpage project that has the same logic and it works for me.

Hi,

I developed a abstract class which is doing the output for me incl. the right header and son on...

may You can use it:

....
public void doProcessBeforeOutput() throws PageException {

		this.init();

		HttpServletResponse servletResponse =
			componentRequest.getServletResponse(true);
		ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

		try {

			OutputStream outputStream = servletResponse.getOutputStream();

			this.makePDF(byteArrayOutputStream);

			servletResponse.setContentType("application/pdf");
			servletResponse.setHeader(
				"Content-Disposition",
				"inline;filename=tmp.pdf");
			servletResponse.setContentLength(byteArrayOutputStream.size());

			servletResponse.setHeader("Expires", "0");
			servletResponse.setHeader(
				"Cache-Control",
				"must-revalidate, post-check=0, pre-check=0");
			servletResponse.setHeader("Pragma", "public");

			byteArrayOutputStream.writeTo(outputStream);
			outputStream.flush();

		} catch (IOException e) {
			log(
				VerzahnungsvorrichtungenPDFFileController.class,
				e.getLocalizedMessage(),
				IEPPLogger.SEVERE);
		}
	}

	/**
	 * To be implemented!!
	 * @param outputStream which includes the PDF
	 */
	protected abstract void makePDF(OutputStream outputStream);

so all You have to is to implemet the makePDF() method.

Within here You can handle Your document

...
try {
			Document document = new Document();
			PdfWriter.getInstance(document, outputStream);
....

You can check this
