I want not to allow users to copy or print the Generated PDF using i-report.
How can i pass parameters for that..

Help me witha tutorial or a coding..

Thanx..

[slow]

It's so beautiful try to find new checkbox in the menu... and I'm not speaking of hidden menu... but simple menu :)

try to do this from the ireport interface:

Tools->Option->Ireport->ExportOption->Pdf->Encryption...


this is the menu item... try to make some tests... I think that not all checks work in the right manner.

Oh...!
Sorry for the misunderstanding...

in this case you can set a lot of parameters for the pdf exportation.
take a look at this code for an idea:

.....
.....
import net.sf.jasperreports.engine.export.JRPdfExporter;
import net.sf.jasperreports.engine.export.JRPdfExporterParameter;
import com.lowagie.text.pdf.PdfWriter;
....
....

JRPdfExporter exp = new JRPdfExporter();

exp.setParameter(JRPdfExporterParameter.IS_128_BIT_KEY, Boolean.TRUE);
exp.setParameter(JRPdfExporterParameter.IS_ENCRYPTED, Boolean.TRUE);
exp.setParameter(JRPdfExporterParameter.USER_PASSWORD, "user_pwd");
exp.setParameter(JRPdfExporterParameter.OWNER_PASSWORD, "owner_pwd");
exp.setParameter(JRPdfExporterParameter.PERMISSIONS,new Integer(PdfWriter.ALLOW_COPY|PdfWriter.ALLOW_PRINTING) );

 

take a look here:
http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/export/JRPdfExporterParameter.html

and here: (some concepts involve IText library...)
http://api.itextpdf.com/com/itextpdf/text/pdf/PdfWriter.html

if you make some google search you can find examples regarding iText pdf encryption (http://www.itextpdf.com/examples/index.php?page=example&id=219 ) or jasperReport simpler code method to so this.

I hope this may help ... good work :)
leave us feedback!
