我知道以前有人问过这个问题。但我真的不知道该怎么做。
我在tomcat服务器上创建了一个j2me应用程序和一个webservice,它在HTTP上工作得很好,Now我需要连接到HTTPS/TLS。
为了做到这一点,我遵循了以下步骤::
当我试图连接到我的https://server-ip/webservice时,使用以下代码片段:
public class HttpsMIDlet extends MIDlet implements CommandListener, Runnable {
private Display mDisplay;
private Form mForm;
public void startApp() {
mDisplay = Display.getDisplay(this);
if (mForm == null) {
mForm = new Form("HttpsMIDlet");
mForm.addCommand(new Command("Exit", Command.EXIT, 0));
mForm.addCommand(new Command("Send", Command.SCREEN, 0));
mForm.setCommandListener(this);
}
mDisplay.setCurrent(mForm);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
public void commandAction(Command c, Displayable s) {
if (c.getCommandType() == Command.EXIT)
notifyDestroyed();
else {
Form waitForm = new Form("Connecting...");
mDisplay.setCurrent(waitForm);
Thread t = new Thread(this);
t.start();
}
}
public void run() {
String url = "https://server-ip/webserive";
try {
// Query the server and retrieve the response.
HttpsConnection hc = (HttpsConnection) Connector.open(url);
SecurityInfo si = hc.getSecurityInfo();
Certificate c = si.getServerCertificate();
String subject = c.getSubject();
System.out.println();
String s = "Server certificate subject: \n" + subject;
Alert a = new Alert("Result", s, null, null);
a.setTimeout(Alert.FOREVER);
mDisplay.setCurrent(a, mForm);
hc.close();
} catch (IOException ioe) {
Alert a = new Alert("Exception", ioe.toString(), null, null);
System.out.println(ioe.toString());
a.setTimeout(Alert.FOREVER);
mDisplay.setCurrent(a, mForm);
}
}抛出此异常:

通过搜索超过15天,这个异常问题通过为tomcat和JDK安装一个旧版本来解决。
这可能发生在区分处理HTTPS/SSL连接的WTK和tomcat/JDK版本时。
for tomcat 1.5for java version JKD 1.5_0_u7我希望这会对其他人有所帮助。
