I can create the pdf file and I can open the pdf file it but my browser
screen does not finish refreshing so end up with a white screen I create the
Birt engine in the application bean with has an application scope
I can create a HTML report and open it in a seperate browser window if I
have to but I would rather have a PDF This is the code I am using
****application bean****
try{
config = new EngineConfig();
config.setEngineHome(
"C:\\birtruntime\\birt-runtime-2_2_0\\ReportEngine" );
config.setLogConfig("c:/birt/logs", Level.FINE);
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
engine.changeLogLevel( Level.WARNING );
}catch( Exception ex){
ex.printStackTrace();
}
I then have a action that uses the engine
public String birtReport2(){
System.out.println("entering birtReport2");
HashMap<String, Integer> parameters = new HashMap<String,
Integer>();
String name = "requestid";
Integer pvalue = new Integer(4);
parameters.put(name, 9667);
FacesContext faces = FacesContext.getCurrentInstance();
HttpServletResponse resp = (HttpServletResponse)
faces.getExternalContext
().getResponse();
HttpServletRequest req=(HttpServletRequest)
faces.getExternalContext().getRequest();
resp.setContentType( "application/pdf" );
resp.setHeader ("Content-Disposition","attachment;
filename=/output.pdf");
ServletContext sc = req.getSession().getServletContext();
PDFRenderContext renderContext = new PDFRenderContext();
HashMap<String, PDFRenderContext> contextMap = new
HashMap<String,
PDFRenderContext>();
contextMap.put( EngineConstants.APPCONTEXT_PDF_RENDER_CONTEXT,
renderContext );
IReportRunnable design;
try
{
//Open report design
design =
FacesUtils.getApplicationBean().getEngine().openReportDesign(sc.getRealPath
("app/birt/compliancerecycle.rptdesign"));
//create task to run and render report
IRunAndRenderTask task =
FacesUtils.getApplicationBean().getEngine()
.createRunAndRenderTask( design );
task.setAppContext( contextMap );
//set output options
PDFRenderOption options = new PDFRenderOption();
//options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML);
options.setOutputFormat(PDFRenderOption.OUTPUT_FORMAT_PDF);
// options.setOutputFileName(filename);
//System.out.println("options.getOutputFileName()"+options.getOutputFileName());
options.setOutputFormat("pdf");
options.setOutputStream(resp.getOutputStream());
task.setRenderOption(options);
//run report
task.run();
task.close();
faces.responseComplete();
}catch (Exception e){
e.printStackTrace();
}
System.out.println("leaving birtReport2");
return "null";
}
I have also tried it with the HTMLRenderContext and HTMLRenderOption with
the same results
