private static IOObject myExampleSet;

public static void main(String[] args) throws Exception {
		JFrame frame = new JFrame("Decision Tree Renderer Test");
		frame.setLocation(0, 0);
		JLabel label = new JLabel();
		frame.add(new JScrollPane(label));
		// Path to process-definition

// final String processPath =
		// "/C:/Users/Administrator/.RapidMiner/repositories/Local
		// Repository/processes/filter1.rmp";
		final String processPath = "/C:/Users/Administrator/.RapidMiner/repositories/Local Repository/processes/clustermodel.rmp";
		// final String processPath =
		// "/C:/Users/Administrator/.RapidMiner/repositories/Local
		// Repository/processes/joinaggregate.rmp";
		// String processPath =
		// "/C:/Users/Administrator/.RapidMiner/repositories/Local
		// Repository/processes/Desctree.rmp";

try {

// Init RapidMiner
			RapidMiner.setExecutionMode(ExecutionMode.EMBEDDED_WITH_UI);
			Plugin.setInitPlugins(true);
			RapidMiner.init();

// Load process
			final com.rapidminer.Process process = new com.rapidminer.Process(new File(processPath));

IOContainer ioResult = process.run();
			IOObject result = ioResult.getElementAt(0); // or whatever index you
														// need
			String name = RendererService.getName(result.getClass());
			List renderers = RendererService.getRenderers(name);

for (Renderer renderer : renderers) { // you don't really need to
				// iterate over this, it's
				// probably only one anyway
				// ;)XJ
				IOContainer dummy = new IOContainer();
				// edit size of image here
				int imgWidth = 1000;
				int imgHeight = 800;
				Reportable reportable = renderer.createReportable(result, ioResult, imgWidth, imgHeight);
				if (reportable instanceof Renderable) {
					Renderable renderable = (Renderable) reportable;
					renderable.prepareRendering();
					int preferredWidth = renderable.getRenderWidth(400);
					int preferredHeight = renderable.getRenderHeight(400);
					final BufferedImage img = new BufferedImage(imgWidth, imgHeight, BufferedImage.TYPE_INT_RGB);
					Graphics2D graphics = (Graphics2D) img.getGraphics();
					graphics.setColor(Color.WHITE);
					graphics.fillRect(0, 0, imgWidth, imgHeight);
					// scale to whatever you need
					graphics.scale(2, 2);
					renderable.render(graphics, preferredWidth, preferredHeight);
					label.setIcon(new ImageIcon(img));

}
			}

frame.setVisible(true);
			frame.pack();
			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

System.out.println(ioResult);

} catch (Exception ex) {

}
