Birt Engine exception with Rational 8

hbtmus

Hi All,

I am new to Birt and this is my first experience. I try to launch a birt report in a servlet code. Development environment is IBM Rational 8.

If I run it as a Java program it works. The same code is not working on the servelt!

All help is very appreciated.

Thanks
Herbert

CODE:

try{
EngineConfig config = new EngineConfig( );
config.setLogConfig("c:/Spirit/birtlog", Level.FINE);
//config.setEngineHome( "C:/birtruntime/ReportEngine" );


Platform.startup( config ); //If using RE API in Eclipse/RCP application this is not needed.
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
IReportEngine engine = factory.createReportEngine( config );
engine.changeLogLevel( Level.WARNING );

IReportRunnable design = engine.openReportDesign("C:/Spirit/workspace/SpiritReport/test.rptdesign");

//Create task to run and render the report,
IRunAndRenderTask task = engine.createRunAndRenderTask(design);

//Setup rendering to PDF
IRenderOption options = new RenderOption();
options.setOutputFormat("pdf");
options.setOutputFileName("C:/Spirit/birtReports/test.pdf");


PDFRenderOption pdfOptions = new PDFRenderOption( options );

task.setRenderOption(pdfOptions);
//run and render report
task.run();
task.close();

engine.destroy();
Platform.shutdown();


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

Do you know what version of BIRT is being used? I assume earlier than 3.7. If so you need to set a birt home:
//config.setEngineHome( "C:/birtruntime/ReportEngine" );
