Have a look at these free pdf renderer ...

Some links ...

2. http://www.jpedal.org/support_siEclipse.php (now at https://www.idrsolutions.com/jpedal/ - commercial)

UPDATE

As per http://www.icepdf.org/ ,

ICEpdf is an open source Java PDF engine that can render, convert, or extract PDF content within any Java application or on a Web server.

For basic functionality you have to include icepdf-core.jar and icepdf-viewer.jar in your class path. Depending upon the requirement you can also add the SVG support.

Taken from iceface sample folder:

import org.icepdf.ri.common.SwingController;
import org.icepdf.ri.common.SwingViewBuilder;

import javax.swing.*;

/**
 * The <code>ViewerComponentExample</code> class is an example of how to use
 * <code>SwingController</code> and <code>SwingViewBuilder</code>
 * to build a PDF viewer component.  A file specified at the command line is
 * opened in a JFrame which contains the viewer component.
 *
 * @since 2.0
 */
public class ViewerComponentExample {
    public static void main(String[] args) {
        // Get a file from the command line to open
        String filePath = args[0];

        // build a component controller
        SwingController controller = new SwingController();

        SwingViewBuilder factory = new SwingViewBuilder(controller);

        JPanel viewerComponentPanel = factory.buildViewerPanel();

        // add interactive mouse link annotation support via callback
        controller.getDocumentViewController().setAnnotationCallback(
                new org.icepdf.ri.common.MyAnnotationCallback(
                        controller.getDocumentViewController()));

        JFrame applicationFrame = new JFrame();
        applicationFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        applicationFrame.getContentPane().add(viewerComponentPanel);

        // Now that the GUI is all in place, we can try openning a PDF
        controller.openDocument(filePath);

        // show the component
        applicationFrame.pack();
        applicationFrame.setVisible(true);
    }
}

The above code helps you in displaying a PDF on a swing component. You can do the same in the SWT environment (have a look at SwingViewBuilder .. kind of hard, but will SWT look and feel ) or use org.eclipse.swt.awt.SWT_AWT (kind of easy... but will have swing + swt look and feel)... though both approach will solve your purpose. Also check the applicable licenses in the license folder.

Hope this will help.

Here is another free, small and powerful PDF Viewer based on Eclipse SWT and jPod Renderer — JPview. It has strong rendering and low memory usage.
