Running A PDF file Error .Help!

[sachinmdev]

I am using JasperReports 2.0.5,Eclipse 3.3.2 and Tomcat 5.0.28. I have wrote a java class to compile the jrxml and i got two files namely .jasper and .jrprint. Then I am using servlet to get the .jasper file and i have to display the pdf file in browser.

But iam getting some string values in the browser. PDF is not displayed. Please help me to solve this problem.

 

My Servlet Code:

 

Code:

public class DemoReport extends HttpServlet implements Servlet {

	
	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
	
		doPost(request, response);
	}
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		ServletOutputStream outputStream = response.getOutputStream();
		InputStream inputStream = getServletConfig().getServletContext().getResourceAsStream("/reports/FirstReport.jasper"«»);
	try {
			JasperRunManager.runReportToPdfStream(inputStream, outputStream, new HashMap(), new JREmptyDataSource());
			response.setContentType("application/pdf"«»);
			outputStream.flush();
			outputStream.close();
		} catch (JRException e) {
			StringWriter stringWriter = new StringWriter();
			PrintWriter printWriter = new PrintWriter(stringWriter);
			e.printStackTrace(printWriter);
			response.setContentType("text/plain"«»);
			response.getOutputStream().print(stringWriter.toString());
		}
	}
}

 

Iam getting this output only in browser. It seems to be the stream is not converted properly.

Code:

You are getting pdf file, which is displayed in browser like text-plain.

 

Try my code:

 

Code:

JasperDesign jasperDesign = JRXmlLoader.load(jrxmlDir+jrxml);		JasperCompileManager.compileReportToFile(jasperDesign,fileName);
InputStream fileStream =new DataInputStream(new FileInputStream(fileName));	JasperRunManager.runReportToPdfStream(fileStream, servletOutputStream, map, dataSource);
fileStream.close();
servletOutputStream.flush();
servletOutputStream.close();

 

fileName is *.jasper file.

Hi,

I got the same output with your code also.

I am using IE 6.0. I concluded the problem with IE only(Is it a bug?). Then Mozilla comes to my mind. I have checked it in mozilla. Both of our code works fine in Mozilla Firefox 2.0.0.12. So what is the compatible version of IE for JasperReports 2.0.5?

:)

I have checked JasperReports 2.0.5 in IE 7. Its working. It doesn't open the PDF in browser,instead it opens a prompt. I think this is the behavior of IE. You have to save the file to .pdf format to view the file. Otherwise it will be saved in default format only.B)

IE 6.0 might have a problem with PDFs when the response content length is not set. To set it, you would have to export the PDF into a temp file or into an in-memory buffer, use the temp/buffer size to do response.setContentLength() and then write the data into the response stream. See the source of net.sf.jasperreports.j2ee.servlets.PdfServlet.

 

HTH,

Hi lucianc,

Thankyou very much. I have set the content length as in the following example and it now works in IE 6.0 also.
