Report generation using Java objects

sabu22

<p>Hi all,

I am facing an issue for generating reports using java objects. Actually i require help in creating a java method whic will help me in generating reports with
java objects as an input.

I had done it previously using xmls as input to birt

The code is as follows:


public void generate(String xmlInput, String xsltInput)
throws BirtException, UnsupportedEncodingException,
TransformerException {
  // open report design
  this.setBirtEngine();
  // open report design
  design = birtEngine.openReportDesign(getClass().getClassLoader()
  .getResourceAsStream(designTemplateName));  // The designTemplate is the rptdesign
  // create task to run and render report
  IRunAndRenderTask task = birtEngine.createRunAndRenderTask(design);

  // Added for dynamic dataSource:Start
  Map appContext = task.getAppContext();
  String transformedApplicationXML = transform(xmlInput, xsltInput);  //creating the xml source to pass in BIRT

  appContext.put(
  "org.eclipse.datatools.enablement.oda.xml.inputStream",
  new ByteArrayInputStream(transformedApplicationXML
  .getBytes("UTF-8")));

  // Use closeInputStream (true) to let BIRT automatically close the
  // inputStream.
  appContext.put(
  "org.eclipse.datatools.enablement.oda.xml.closeInputStream",
  true);

  // create task to run and render report
  String pdfFileName = "Report" + ".pdf";
  PDFRenderOption options = new PDFRenderOption();
  options.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");
  options.setOutputFormat("pdf");
  options.setOutputFileName(APPFOLDERPATH);
  options.setOutputFileName(pdfFileName);
  task.setRenderOption(options);
  task.run();
  task.close();
 }

The above code uses xml as input to BIRT similarly i need to pass a java object to birt.

Any help is appreciated

Thanks</p>

<p>What version of BIRT are you using?  BIRT 4.3+ has a POJO data source.  If you're not using 4.3+, there are several devShares that are aimed at using POJOs with BIRT, using a scripted dataset.</p>
