Hi,
I am trying to generate pdf report.
It is generating the pdf file in the path...but it is not rendered automatically..also as i tried to open the pdf file manually...
Adobe Reader could not open 'sample.pdf'" because it is either not a supported file type or because the file has been corrupted (for example, it was sent as an email attachment and wasn't correctly decoded)
Please help me to resolve the issue....Please provide sample code or link if possible.
I am using the below code.(I am executing the code in tomcat server(struts2))
EngineConfig conf = new EngineConfig();
ReportEngine eng = null;
IReportRunnable design = null;
IRunAndRenderTask task = null;
String reportName = "sample.rptdesign";
String path = servletContext.getRealPath("");
String reportDirectoryPath = path + System.getProperty("file.separator") + "birtreports";
String engineHome = path + System.getProperty("file.separator") + "WEB-INF";
conf = new EngineConfig();
conf.setEngineHome(engineHome);
eng = new ReportEngine( conf );
String reportPath = path + System.getProperty("file.separator") + "birtreports" + System.getProperty("file.separator") + reportName ;
try
{
design = eng.openReportDesign(reportPath);
}
catch (Exception e)
{
System.err.println("An error occured during the opening of the report file!");
e.printStackTrace();
}
//With the file open, create the Run and Render task to run the report
task = eng.createRunAndRenderTask(design);
String fileName = reportDirectoryPath + System.getProperty("file.separator") + "sample"+ ".pdf";
System.out.println("File Name is : " + fileName);
PDFRenderOption pdfOptions = new PDFRenderOption( );
pdfOptions.setOption( IPDFRenderOption.FIT_TO_PAGE, new Boolean(true) );
pdfOptions.setOption( IPDFRenderOption.PAGEBREAK_PAGINATION_ONLY, new Boolean(true) );
pdfOptions.setOutputFileName(fileName);
task.setRenderOption(pdfOptions);
//Set parent classloader for engine
task.getAppContext().put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY, ReportAction.class.getClassLoader());
//Cross our fingers and hope everything is set
try
{
task.run();
task.close();
}
catch (Exception e)
{
System.err.println("An error occured while running the report!");
e.printStackTrace();
//System.exit(-1);
}
//Yeah, we finished. Now destroy the engine and let the garbage collector
//do its thing
System.out.println("All went well. Closing program!");
eng.destroy();
Thanks,
balachandar

Are you running this as a servlet? What version are you using?
Have a look at this wiki page:
http://wiki.eclipse.org/Servlet_Example_%28BIRT%29_2.1

If you want to export in many formats, make sure to use a run task and
then a render task. The reason for this is that for each of the formats
you will not have to re-run the report. If you use a runandrendertask
you will have to run the report for each format.
You may want to read over this:
http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.php
and
http://www.birt-exchange.org/org/devshare/deploying-birt-reports/1344-eclipsecon-2011-api-examples/
For Books you may want to look at
"BIRT A Field Guide to Reporting" Version 3
"Integrating and Extending BIRT" Version 3
