This sample project shows the possibility of creating a report in runtime and show it in the viewer. All you need is the native Java viewer to display report, and a few lines of code to create the report with components.

First, we need to create the Java viewer. Create the JFrame, set the necessary options and add the viewer control:

public class CreateReport extends JPanel {

	private static final long serialVersionUID = 330448692680237867L;
	private static final Dimension FRAME_SIZE = new Dimension(800, 800);
	
	public static void main(final String[] args) {
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				try {
					JFrame frame = new JFrame();
					frame.add(new CreateReport(frame));
					frame.setSize(FRAME_SIZE);
					frame.setLocationRelativeTo(null);
					frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
					frame.setVisible(true);
				} catch (Throwable e) {
					StiExceptionProvider.show(e, null);
				}
			}
		});
	}
	
	public CreateReport(final JFrame parentFrame) throws FileNotFoundException {
		setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
		setPreferredSize(FRAME_SIZE);
		StiViewerFx viewerPanel = new StiViewerFx(parentFrame);
		add(viewerPanel);

...

Next, create the new report object, then create the XML datatase object with the path to the Demo XML and XSD files, and add it to the report:

...

		StiReport report = new StiReport();
	
		StiPage page = new StiPage(report);
		report.getPages().add(page);
		page.setName(StiNameCreation.createName(report, StiNameCreation.generateName(page)));
		String xsdPath = "/samples/Demo.xsd";
		StiXmlDatabase xmlDatabase = new StiXmlDatabase("Demo",
			StiResourceUtil.getStream(xsdPath), StiResourceUtil.getStream("/samples/Demo.xml"));
		report.setDictionary(new StiDictionary(report));
		report.getDictionary().getDatabases().add(xmlDatabase);

...

Next, extract information from the Demo database and create the TableSource with 'Categories' name:

...

		StiXmlTableFieldsRequest tables = StiDataColumnsUtil.parceXSDSchema(StiResourceUtil.getStream(xsdPath));
		StiDataTableSource tableSource = null;
		for (StiXmlTable table : tables.getTables()) {
			if (table.getName().equals("Categories")) {
				tableSource = new StiDataTableSource("Demo." + table.getName(), table.getName(), table.getName());
				tableSource.setColumns(new StiDataColumnsCollection());
				for (StiSqlField field : table.getColumns()) {
					StiDataColumn column = new StiDataColumn(field.getName(), field.getName(), field.getSystemType());
					tableSource.getColumns().add(column);
				}
				tableSource.setDictionary(report.getDictionary());
				report.getDictionary().getDataSources().add(tableSource);
			}
		}

...

Now we need to create the report components. First, add the Header band to the report page with Text component. These componentst will display the report title:

...

		// Create TitleBand
		StiHeaderBand titleBand = new StiHeaderBand();
		titleBand.setHeight(0.85);
		titleBand.setName("TitleBand");
		page.getComponents().add(titleBand);
		
		// Create Title text on header
		StiText headerText = new StiText(new StiRectangle(0, 0, page.getWidth(), 0.85));
		headerText.setTextInternal("Tacticdescription");
		headerText.setHorAlignment(StiTextHorAlignment.Left);
		headerText.setName("TitleHeader");
		headerText.setFont(new StiFont("Arial", 12F, StiFontStyle.Bold));
		titleBand.getComponents().add(headerText);
		
		// Create HeaderBand
		StiHeaderBand headerBand = new StiHeaderBand();
		headerBand.setHeight(0.5);
		headerBand.setName("HeaderBand");
		page.getComponents().add(headerBand);

...

Next, add the Data band with the Text fields and Image field. These components will display the report data:

...

		double pos = 0;
		double columnWidth = page.getWidth() / tableSource.getColumns().size();
		Integer nameIndex = 1;
		for (StiDataColumn dataColumn : tableSource.getColumns()) {
			// Create text on header
			StiText hText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
			
			hText.setTextInternal(dataColumn.getName());
			hText.setHorAlignment(StiTextHorAlignment.Center);
			hText.setName("HeaderText" + nameIndex.toString());
			hText.setBrush(new StiSolidBrush(StiColorEnum.Orange.color()));
			hText.getBorder().setSide(StiBorderSides.All);
			headerBand.getComponents().add(hText);
			
			if (dataColumn.getName().equals("Picture")) {
				StiImage dataImage = new StiImage(new StiRectangle(pos, 0, columnWidth, 0.5));
				dataImage.setDataColumn("Categories." + dataColumn.getName());
				dataImage.setName("DataImage" + nameIndex.toString());
				dataImage.getBorder().setSide(StiBorderSides.All);
				dataBand.getComponents().add(dataImage);
			} else {
				StiText dataText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
				dataText.setText("{Categories." + dataColumn.getName() + "}");
				dataText.setName("DataText" + nameIndex.toString());
				dataText.getBorder().setSide(StiBorderSides.All);
				dataBand.getComponents().add(dataText);
			}
			pos = pos + columnWidth;
			nameIndex++;
		}

...

Finally, render the report and show it in the viewer:

...

		report.Render();
		
		viewerPanel.getStiViewModel().getEventDispatcher().dispatchStiEvent(
			new StiViewCommonEvent(StiViewCommonEvent.DOCUMENT_FILE_LOADED, new StiDocument(report), null));
	}

In the screenshot below you can see the result of the sample code:
