Problem streaming PDF to IE using SSL

2004-06-16 15:14

I'm using Struts action classes to handle requests. For reports, it then calls into my backend code to execute the report and stream back the byte[].

 

Once the Action class has the byte[], I set the following in the response:

 

setContentType("application/pdf");

setContentLength(reportBytes.length);

 

Then I write the byte[] into the response's outputStream, flush, and close.

 

All of this works perfect when using a non-secure site (ie. no SSL). When I try to deploy this to a site using SSL, IE complains stating that

 

"... Internet Explorer was not able to open this Internet site..."

 

I have struts nocache set to true. Setting this to false does not make any difference. I've tried physically setting 'Pragma' and 'Cache-control' to be empty and have set the 'Content-disposition' to 'attachment; filename="example.pdf"'. And still no change.

 

What am I missing? I've been trying to crack this nut, off & on, for several weeks.

 

Thanx,

jsh

I found this posting and added "Expires" but it still didn't work.

Any other suggestions?

I suggess you export to a pdf file and then display it on the browser.

 

you have to export with these options :

 

exporter.setParameter(JRPdfExporterParameter.IS_ENCRYPTED, Boolean.TRUE);

exporter.setParameter(JRPdfExporterParameter.IS_128_BIT_KEY, Boolean.TRUE);

I'm currently using JasperRunManager.runReportToPdf() to get the byte[] and then am streaming it back. I've not seen any examples of using the JRPdfExporter (still looking). What other parameters are needed when using this exporter?

 

Thanx,

jsh

Take a look at the source code for the JasperRunManager.runReportToPdf() method. If it is not using the JRPdfExporter, then a method that it is calling is... You can get the sample code you need from one of those methods.

JRPdfExporter exporter = new JRPdfExporter();

 

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_FILE, destFile);

exporter.setParameter(JRPdfExporterParameter.IS_ENCRYPTED, Boolean.TRUE);

exporter.setParameter(JRPdfExporterParameter.IS_128_BIT_KEY, Boolean.TRUE);

exporter.setParameter(JRPdfExporterParameter.USER_PASSWORD, "xx"); (optional)

exporter.setParameter(JRPdfExporterParameter.OWNER_PASSWORD, "xy"); (optional)

exporter.setParameter(

JRPdfExporterParameter.PERMISSIONS,

new Integer(PdfWriter.AllowCopy |

PdfWriter.AllowPrinting)

);

 

exporter.exportReport();
