How to display pdf report in jsp?

[raghavendram040]

I have a link in one jsp as,

 

<form action="VehicleReports">

<a href="vehicleReport.jsp">Vehicle Report</a>

</form>

 

I have writen VehicleReports servlet as,

 

 

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

 

Connection con=null;

try{

 

response.setContentType("application/pdf"); 

 

con=VehicleDetails.getConnection();

InputStream inputStream = new FileInputStream ("E:/ReportFld/report4.jrxml");

 

Map parameters = new HashMap();

 

JasperDesign jasperDesign = JRXmlLoader.load(inputStream);

JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

@SuppressWarnings("unchecked")

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, con);

 

JasperExportManager.exportReportToPdfFile(jasperPrint, "D:/reports/vehicle2_jasper.pdf");

 

JasperExportManager.exportReportToPdfFile(jasperPrint, "D:/reports/vehicle2_jasper.pdf");

 

 

   int len = (int)new File("D:/reports/vehicle2_jasper.pdf").length(); 

response.setContentLength(len); 

byte[] buf = new byte[len]; 

FileInputStream pdfin = new FileInputStream("D:/reports/vehicle2_jasper.pdf"); 

pdfin.read(buf); 

pdfin.close(); 

OutputStream pdfout = response.getOutputStream(); 

pdfout.write(buf,0,len); 

pdfout.flush();  

 

request.getRequestDispatcher("/vehicleReport.jsp").forward(request, response);

 

 

}

catch(Exception e){e.printStackTrace();}

finally{

try {

con.close();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

<object data="D:/reports/vehicle2_jasper.pdf" type="application/pdf">

<embed src="D:/reports/vehicle2_jasper.pdf" type="application/pdf">
