Client side JasperReports printing?

Question

I developed a web application that uses JasperReports. I noticed that reports print to the server side.

How to force reports to print on the client side (from a web browser)?

Any ideas would be helpful.

Assuming you have a server architecture:

• Get the HttpServletResponse instance handle with HttpServletResponse response = this.getThreadLocalResponse(); (eg).
• Set various headers to indicate attachment of the file.

    HttpServletResponse response = getServletResponse ();
   response.setHeader ("Content-Description", "File Transfer");
   response.setHeader ("Content-Disposition", "attachment; filename =" +
     "report.pdf");
   response.setHeader ("Content-Type", "application / pdf");
   response.setHeader ("Content-Transfer-Encoding", "binary");
  

• Configure JRExporter (jre) to use the HttpServletRespone output stream:

    jre.setParameter( JRExporterParameter.OUTPUT_STREAM, getOutputStream() ); 

• Run the report.

The browser will prompt the user to save the report as a PDF file. User can print PDF.
