JDIC 访问Web时NullPointerException

Exception in thread "EventThread" java.lang.NullPointerException
            at org.jdesktop.jdic.browser.internal.MsgClient.<init>(Unknown Source)
            at org.jdesktop.jdic.browser.internal.NativeEventThread.run(Unknown Source)

 

该错误原因为pc默认浏览器不是Ie引起的，在声明里设置默认浏览器即可解决。

public class BrowserTest {

    static {

        BrowserEngineManager engineManager = BrowserEngineManager.instance();

        engineManager.setActiveEngine(BrowserEngineManager.IE);

    }



    public static void main(String[] args) throws Exception {

        WebBrowser browser = new WebBrowser();

        browser.setURL(new URL("http://www.baidu.com"));

        JFrame frame = new JFrame("Browser Test");

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.getContentPane().add(browser);

        frame.pack();

        frame.setSize(500, 500);

        frame.setVisible(true);

    }

}
