You can create either a run task or render task in the after render
event handler to do what you want. You could enter a script like this
to do just a render (note example is in JavaScript but could be done in
Java).
rptdoc =
reportContext.getHttpServletRequest().getAttribute("attributeBean ").getReportDocumentName();
importPackage(Packages.org.eclipse.birt.report.engine.api);
var re = reportContext.getReportRunnable().getReportEngine();
var mdocument = re.openReportDocument(rptdoc);
var options = new PDFRenderOption();
options.setOutputFormat("pdf");
options.setOutputFileName("c:/test/mytest.pdf");
var ntask = re.createRenderTask(mdocument);
ntask.setRenderOption(options);
ntask.render();
ntask.close();
This code has no error checking in it. You also may want to put a check
in to see if you are in the designer and not run the code if you are.
reportContext.getHttpServletRequest().getAttribute("attributeBean ").isDesigner();
Here is an example of doing a run and render task:
importPackage(Packages.org.eclipse.birt.report.engine.api);
var re = reportContext.getReportRunnable().getReportEngine();
var des = re.openReportDesign("c:/xfer/burstdetail.rptdesign");
var ntask = re.createRunAndRenderTask(des);
ntask.setParameterValue("CustomerNumber",
this.getRowData().getColumnValue(0).toString() );
var options = new PDFRenderOption();
var outputfile = "c:/temp/test" + this.getRowData().getColumnValue(0) +
".pdf";
options.setOutputFileName(outputfile);
options.setOutputFormat("pdf");
ntask.setRenderOption(options);
ntask.run();
ntask.close();

Try adding
mdocument.close();
after you close the task.

Try this (again with no error checking):
mmap =
reportContext.getHttpServletRequest().getAttribute("attributeBean ").getModuleOptions();
rptdoc =
reportContext.getHttpServletRequest().getAttribute("attributeBean ").getReportDocumentName();
importPackage(Packages.org.eclipse.birt.report.engine.api);
importPackage(Packages.java.io)
var re = reportContext.getReportRunnable().getReportEngine();
var mdocument = re.openReportDocument(null,rptdoc, mmap);
var options = new PDFRenderOption();
baos = new ByteArrayOutputStream();
options.setOutputFormat("pdf");
options.setOutputStream(baos);
var ntask = re.createRenderTask(mdocument);
ntask.setRenderOption(options);
ntask.render();
ntask.close();
mdocument.close();
fout = new FileOutputStream("c:/test/myreport.pdf");
fout.write(baos.toByteArray());
fout.flush()
fout.close();

If you are using event scripting to do this look at the attached example
which does a second render in the beforeRendering event.

BIRT does not have any script functions that specifically write back to
a database, but you could always write your own class that inserts into
a db and call it from BIRT event handlers.
