更新

根据 http://www.icepdf.org/ ，

ICEpdf是一个开源的Java PDF
可以在任何Java
应用程序或Web服务器上呈现，转换或
提取PDF内容的引擎。

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.

对于基本功能，您必须在类路径中包含 icepdf-core.jar 和 icepdf-viewer.jar 。根据要求，您还可以添加SVG支持。

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.

取自iceface示例文件夹：

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);
    }
}

以上代码可帮助您在摆动组件。你可以在SWT环境中做同样的事情（看看 SwingViewBuilder ..有点难，但SWT的外观和感觉）或使用 org .eclipse.swt.awt.SWT_AWT （有点简单...但会有swing + swt的外观和感觉）......虽然这两种方法都能解决你的目的。另请检查许可证文件夹中的适用许可证。

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.

希望这会有所帮助。
