到https URL的Java连接

Question

我用Java编写了一个访问URL的小代码。该代码适用于HTTP连接，但不适用于HTTPS（错误粘贴在下面）

如有任何帮助，我们将不胜感激。

代码：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;


public class ConnectToWCProd {

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

        String userPassword = "user1:user1";
        String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());

        //URL oracle = new URL("http://<URL>/");
        URL oracle = new URL("https://<URL>");
        URLConnection yc = oracle.openConnection();

        yc.setRequestProperty("Authorization", "Basic " + encoding);

        BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) 
            System.out.println(inputLine);
        in.close();
    }

}

错误：

您必须在jre/lib/Security/cacerts（默认路径）中包含证书
