My report doesn't show up from servlet

2004-12-21 18:50

Hi all,

 

I have a problem with Jasper report. I've already

design the report using iReport. The report is

just a simple static text. It was already

compile successfully, and I could view using

iReport viewer. But when I tried to run it

from servlet, there's only blank pdf page,

and there's no static text I've written. There

was no error when I tried to debug the code.

What's wrong ? This is snippet of my

source code :

 

try {

ServletContext context = this.getServletConfig().getServletContext();

System.setProperty(

"jasper.reports.compile.class.path",

context.getRealPath("/WEB-INF/lib/jasperreports-0.5.3.jar") +

System.getProperty("path.separator") +

context.getRealPath("/WEB-INF/classes/")

);

 

System.setProperty(

"jasper.reports.compile.temp",

context.getRealPath("/WEB-INF/reports/")

);

 

byte[] bytes = null;

try {

File reportFile = new File(context.getRealPath(

"/WEB-INF/reports/exports/workorder/WorkOrderRpt.jasper"));

Map parameters = new HashMap();

parameters.put("TWORKORDER_PK", "1");

parameters.put("PATH_IMAGE","1");

 

bytes = JasperRunManager.runReportToPdf(reportFile.getPath(),

parameters, new ConnectionFactory().getConnection());

 

if (bytes != null && bytes.length > 0) {

httpServletResponse.setContentType("application/pdf");

httpServletResponse.setContentLength(bytes.length);

ServletOutputStream ouputStream = httpServletResponse.getOutputStream();

ouputStream.write(bytes, 0, bytes.length);

ouputStream.flush();

ouputStream.close();

}

bytes=null;

}

catch (JRException e) {

e.printStackTrace();

return;

}

}

catch (IOException ie) {

ie.printStackTrace();

}

 

}

are you using IE and pdf viewer embedded in broser? Try saving the link instead and see if the report works, there is a bug in IE/pdf in certanin situations
