java swing 浏览网页

目前来说，java swing 中嵌入网页，使用DJNativeSwing是最有效地方法。DJNativeSwing其实是通过内部桥来调用SWT的Browser控件。
附上代码：

public class Mains extends JPanel {
	
	private static final long serialVersionUID = 1L;

	final static public String LS = System.getProperty("line.separator", "/n");

	final static public String FS = System.getProperty("file.separator", "//");

	final static StringBuffer jsDimension;

	static {
		jsDimension = new StringBuffer();
		jsDimension.append("var width = 0;").append(LS);
		jsDimension.append("var height = 0;").append(LS);
		jsDimension.append("if(document.documentElement) {").append(LS);
		jsDimension
				.append("  width = Math.max(width, document.documentElement.scrollWidth);")
				.append(LS);
		jsDimension
				.append("  height = Math.max(height, document.documentElement.scrollHeight);")
				.append(LS);
		jsDimension.append("}").append(LS);
		jsDimension.append("if(self.innerWidth) {").append(LS);
		jsDimension.append("  width = Math.max(width, self.innerWidth);")
				.append(LS);
		jsDimension.append("  height = Math.max(height, self.innerHeight);")
				.append(LS);
		jsDimension.append("}").append(LS);
		jsDimension.append("if(document.body.scrollWidth) {").append(LS);
		jsDimension.append(
				"  width = Math.max(width, document.body.scrollWidth);")
				.append(LS);
		jsDimension.append(
				"  height = Math.max(height, document.body.scrollHeight);")
				.append(LS);
		jsDimension.append("}").append(LS);
		jsDimension.append("return width + ':' + height;");
	}

	public Mains(final String url, final int maxWidth, final int maxHeight) {
		super(new BorderLayout());
		JPanel webBrowserPanel = new JPanel(new BorderLayout());
		final String fileName = System.currentTimeMillis() + ".jpg";
		final JWebBrowser webBrowser = new JWebBrowser(null);
		webBrowser.setBarsVisible(false);
		webBrowser.navigate(url);
		webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
		add(webBrowserPanel, BorderLayout.CENTER);

		JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER, 4, 4));

		webBrowser.addWebBrowserListener(new WebBrowserAdapter() {

			public void loadingProgressChanged(WebBrowserEvent e) {
				//判断是否加载完成
				if (e.getWebBrowser().getLoadingProgress() == 100) {
					//进行网页截图
//					String result = (String) webBrowser
//							.executeJavascriptWithResult(jsDimension.toString());
//					int index = result == null ? -1 : result.indexOf(":");
//					NativeComponent nativeComponent = webBrowser
//							.getNativeComponent();
//					Dimension originalSize = nativeComponent.getSize();
//					Dimension imageSize = new Dimension(Integer.parseInt(result
//							.substring(0, index)), Integer.parseInt(result
//							.substring(index + 1)));
//					imageSize.width = Math.max(originalSize.width,
//							imageSize.width + 50);
//					imageSize.height = Math.max(originalSize.height,
//							imageSize.height + 50);
//					nativeComponent.setSize(imageSize);
//					BufferedImage image = new BufferedImage(imageSize.width,
//							imageSize.height, BufferedImage.TYPE_INT_RGB);
//					nativeComponent.paintComponent(image);
//					nativeComponent.setSize(originalSize);
//					// 
//					if (imageSize.width > maxWidth
//							|| imageSize.height > maxHeight) {
//						// 
//						image = image.getSubimage(0, 0, maxWidth, maxHeight);
//						/*
//						 * int width = image.getWidth(), height =
//						 * image .getHeight(); AffineTransform tx = new
//						 * AffineTransform(); tx.scale((double) maxWidth /
//						 * width, (double) maxHeight / height);
//						 * AffineTransformOp op = new AffineTransformOp(tx,
//						 * AffineTransformOp.TYPE_NEAREST_NEIGHBOR); //锟斤拷小 image
//						 * = op.filter(image, null);
//						 */
//					}
//					try {
//						ImageIO.write(image, "jpg", new File(fileName));
//					} catch (IOException ex) {
//						ex.printStackTrace();
//					}
				}
			}
		}

		);
		add(panel, BorderLayout.SOUTH);

	}

	public static void main(String[] args) {
		NativeInterface.open();
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				JFrame frame = new JFrame("java swing 浏览器");
				frame.getContentPane().add(
						new Mains("http://www.baidu.com", 1024, 768),
						BorderLayout.CENTER);
				frame.setSize(800, 600);
//				frame.invalidate();
//				frame.pack();
				frame.setVisible(true);
			}
		});
		NativeInterface.runEventPump();
	}

需要导入的jar包有：
DJNativeSwing-SWT.jar
DJNativeSwing.jar
swt.jar
运行时如果swt的版本不够，会报以下错误


附上swt4.3的jar包
