点击Swing界面的按钮时超链接到指定Jsp页面
用Swing做的界面,怎样点击一个按钮(或其他组件)就超链接到一个指定的Jsp页面?
程序代码:
package a; import public class BrowserControl { /** * Display a file in the system browser. If you want to display a * file, you must include the absolute path name. * * @param url the file's url (the url must start with either "http://" or * "file://"). */ public static void displayURL(String url) { boolean windows = isWindowsPlatform(); String cmd = null; try { if (windows) { // cmd = 'rundll32 url.dll,FileProtocolHandler http://...' cmd = WIN_PATH + " " + WIN_FLAG + " " + url; Process p = Runtime.getRuntime().exec(cmd); } else { // Under Unix, Netscape has to be running for the "-remote" // command to work. So, we try sending the command and // check for an exit value. If the exit command is 0, // it worked, otherwise we need to start the browser. // cmd = 'netscape -remote openURL(<span style="color: #008000; text-decoration: underline;">http://www.[/color])' cmd = UNIX_PATH + " " + UNIX_FLAG + "(" + url + ")"; Process p = Runtime.getRuntime().exec(cmd); try { // wait for exit code -- if it's 0, command worked, // otherwise we need to start the browser up. int exitCode = p.waitFor(); if (exitCode != 0) { // Command failed, start up the browser // cmd = 'netscape <span style="color: #008000; text-decoration: underline;">http://www.[/color]' cmd = UNIX_PATH + " " + url; p = Runtime.getRuntime().exec(cmd); } } catch(InterruptedException x) { System.err.println("Error bringing up browser, cmd='" + cmd + "'"); System.err.println("Caught: " + x); } } } catch(IOException x) { // couldn't exec browser System.err.println("Could not invoke browser, command=" + cmd); System.err.println("Caught: " + x); } } /** * Try to determine whether this application is running under Windows * or some other platform by examing the "os.name" property. * * @return true if this application is running under a Windows OS */ public static boolean isWindowsPlatform() { String os = System.getProperty("os.name"); if ( os != null && os.startsWith(WIN_ID)) return true; else return false; } /** * Simple example. */ public static void main(String[] args) { displayURL("http://www.); } // Used to identify the windows platform. private static final String WIN_ID = "Windows"; // The default system browser under windows. private static final String WIN_PATH = "rundll32"; // The flag to display a url. private static final String WIN_FLAG = "url.dll,FileProtocolHandler"; // The default browser under unix. private static final String UNIX_PATH = "netscape"; // The flag to display a url. private static final String UNIX_FLAG = "-remote openURL"; }
