JSC with jasper report

That was actually a pretty detailed link, but for just the nuts and bolts, here are a

couple methods from an application that generates a Jasper report and creates a

PDF for viewing or saving to file.

The first method creates a JasperPrint object using a compiled report from iReports.

The second method creates a pdf formatted report from the JasperPrint object and

prompts the client for viewing or saving the pdf file.

The report itself was created using iReport and compiled to generate a Report.jasper file as input to the JasperFillManager.fillReport() method.

This uses Jasper Reports 1.3.2 libraries and seems to work fine.

Hope this helps.

// Create report

public boolean createIoReport()

{

JasperPrint jp=null;

JasperReport jr = null;

String s1 = getRptIoStart();

String s2 = getRptIoEnd();

if( !checkRptDateFields( s1, s2 ) )return false;

if( !hasStartDate )s1 = s2;

if( !hasEndDate )s2 = s1;

try

{

int k = Integer.parseInt( getSelectedDirection());

String title = "Inbound Report for " + s1;

if( !startDate.equals( endDate ))title = title + " to " + s2;

// Add report input parameters

Map parameters = new HashMap();

parameters.put( "p_inOut", new Integer(k) );

parameters.put( "p_start_date", startDate );

parameters.put( "p_end_date", endDate );

parameters.put( "p_title", title );

// Fill the report 'conn' is database connection

jp = JasperFillManager.fillReport( reportDir+"InOut_Report.jasper", parameters, conn );

// Create the PDF

doPdfReport( jp, "InboundReport" );

}

catch( Exception e )

{

log( "<SessionBean1.createIoReport> Error: "+ e.toString());

return false;

}

return true;

}

// Servlet part to display report in Adobe

public void doPdfReport( JasperPrint reportout, String filename )

{

byte[] pdf =null;

// Create the pdf formatted report stream

try {

pdf = JasperExportManager.exportReportToPdf(reportout);

}

catch (JRException ex3) {

error("Couldn't create PDF: "+ex3);

}

// Set up the servlet stuff

FacesContext faces = javax.faces.context.FacesContext.getCurrentInstance();

HttpServletResponse response =(HttpServletResponse)faces.getExternalContext().getResponse();

// Some additional setup parameters

response.setContentType("application/pdf");

response.setContentLength(pdf.length);

response.setHeader("Content-disposition","attachment; filename=\""+filename+".pdf\"");

ServletOutputStream out;

try{

// Send the report stream to the servlet

out = response.getOutputStream();

out.write(pdf);

}catch (Exception qw){

error("Could not output file:"+qw);

}

faces.responseComplete();

}
