It is very Easy: (considering the scenario)

when u click on "Generate Report" button call java scripting function

window.open ('/file.jsp?param1=val&param2=val2','','toolbar=yes')

 

where file.jsp is the jsp(make sure the path is right) that creates the pdf report and send the parameters if required along with the url

 

this will open a window of IE in which acrobat is present

Hope this will help

Try setting "Content-Disposition: INLINE" in the response header. This should (theoretically) invoke the Acrobat reader plugin provided all the other header variables are set appropriately.

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, response.getOutputStream());

exporter.exportReport();

Give some dummy name for the file name, say response.setHeader("Content-disposition", "inline; filename=test.pdf");

 

The name will only be used if someone tries to save the file once it has been displayed within the browser.

Look my code:

}else if (formatRapport.equals("pdf")){

//JasperExportManager.exportReportToPdfStream(jasperPrint,outStr);

response.setContentType("application/pdfred; charset=windows-1252");

response.setHeader("Content-disposition", "inline; filename=test.pdf");

JRPdfExporter exporter = new JRPdfExporter();

exporter.setParameter(JRHtmlExporterParameter.CHARACTER_ENCODING, "iso-8859-1");

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, response.getOutputStream());

exporter.exportReport();

}

 

i'm get demoralized :'-(

RE: open pdf in my browser IE

2006-05-19 07:35

yes, it's the same result.

 

but it work in mozilla. I prefer it work in IE. I must be read, it's a bug between acrobat and ie.

It's called "blank page syndrome".

I think that we must wait :-S

 

tanks for your help Sanjeev,

It is in fact a bug (or expected behavior as is always the case) with IE. When using content-disposition, IE receives the data and tries to start the plug-in associated with it. Then, for some unknown reason it forget's the content-type and requires another call to be made just to retrieve the content type.

 

You can read up on it. It's pretty interesting. Just one more thing. If you start Adobe in the background before you run the report, does it still display a blank page?

Setting response.setContentLength() to the size of the jasperPrint object is another recommended step for handling content-disposition for IE.

yes, it display always a blank page.

 

 

for the second request,

response.setContentLength(?????)

What do i write?

A hint?

response.setContentLength() is maybe the solution but in jsp, i haven't the length of my report.

 

when i write a random number:

for example 1000:

 

my browser display:

Char 49/Encoding<>/Widths[556]>> endobj 6 0 obj<> endobj 8 0 obj<> endobj 9 0 obj<> endobj 10 0 obj<> endobj 11 0 obj<> endobj xref 0 12 0000000000 65535 f 0000000543 00000 n 0000000751 00000 n 0000000838 00000 n 0000000930 00000 n 0000000015 00000 n 0000001076 00000 n 0000000717 00000 n 0000001126 000001210 00000 n 0000001267 00000 n trailer <<1facf254fb5d50f30c16e29ddcdd7e74>]/Root 10 0 R/Size 12/Info 11 0 R>> startxref 1464 %%EOF

Instead of JRExporterParameter.OUTPUT_STREAM = response.getOutputStream(), set it to a ByteArrayOutputStream. That'll allow you to get the length of the report from there. After that, you just need to write the contents of the ByteArrayOutputStream to the response.

Please forgive me, if I sound very stupid..

 

What i understand is that when you print a report in pdf, its acrobat that opens ur report and IE is blank..

 

This doesn't seems to be problem of jasperreport but issue with ur acrobat preferences.

 

In Acrobat (7.0), Go to Edit> Preference > Internet and check if the flag "display in browser" is checked or unchecked..

to nitzien:

 

you're understand my problem, but all flag checked. It's not the solution, thanks for your help.

 

to Sanjeev:

How can i transform this:

OutputStream outStr = response.getOutputStream();

...

exporter.setParameter(JRHtmlExporterParameter.OUTPUT_STREAM, outStr);

 

i'm difficulty in writing a new type ByteArrayOutputStream.

I try this solution but it don't work.

 

}else if (formatRapport.equals("pdf")){

response.setContentType("application/pdf; charset=windows-1252");

JRPdfExporter exporter = new JRPdfExporter();

exporter.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "iso-8859-1");

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, bArray);

exporter.exportReport();

JRPdfExporter exporter2 = new JRPdfExporter();

response.setContentLength(bArray.size());

exporter2.setParameter(JRPdfExporterParameter.JASPER_PRINT,jasperPrint);

exporter2.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "iso-8859-1");

exporter2.setParameter(JRPdfExporterParameter.OUTPUT_STREAM,response.getOutputStream());

exporter2.exportReport();

}

 

my pdf is open by acrobat reader and not by IE.

another solution?

Hi, I'm working with displaying report in pdf format in browser like you, maybe you can try as follow:

 

byte[] bytes = JasperRunManager.runReportToPdf(path, params, conn);

response.setContentLength(bytes.length); ServletOutputStream outputStream = response.getOutputStream();

outputStream.write(bytes, 0, bytes.length);

outputStream.flush();

outputStream.close();

 

I compiled jrxml file to jasper file by iReport and succeed with old version, but when I use newest version (1.2.2), it always shows the error about incompatible serialVersionUID: stream class = 607, local class = 604.

Hello

 

Most likely this is a IE related problem, and has nothing to do with content length or disposition. The JasperReports team never had such problems with PDF, the only export that needed content length was the XLS. So, since it works in Mozilla, probably it's the IE plugin for Adobe that's causing the problem. I had the same problem on my home computer, although the same code worked on other computers.

i have this problem only with pdf exporter. Xls, html,cvs are ok.

 

i use the servlet and my code is :

 

byte[] pdfByteArray = JasperExportManager.exportReportToPdf(jasperPrint);

res.setContentType("application/pdf;charset=windows-1252");

res.setHeader("Content-disposition","inline; filename=Prova.pdf");

res.setContentLength(pdfByteArray.length);

ServletOutputStream out = res.getOutputStream();

out.write(pdfByteArray, 0, pdfByteArray.length);

out.flush();

out.close();

 

Thanks and sorry for my english :)

Hi

 

What iText version do you have on your classpath? JR versions >= 1.1.1 need iText >= 1.02(b). The requirements page states that iText >= 1.01 is needed, we'll have to fix the discrepancy.

 

Regards,

Lucian

iText 1.01 compatibility has been restored on CVS. The fix will be part of the next release.

Are you sure about this?

 

The stack trace you posted does not correspond to 0.6.5 sources (you can check this yourself). Are you using modified sources?
