java https请求问题
jdk1.4.2
使用httpclient 向一个用https的网站发起一个请求
报错如下
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found

已经从那个网站上面把证书下载了，用keytool导入证书
用keytool 导入了 证书
keytool -import -trustcacerts -keystore c:\ca.jks -file c:\ca.cer

依然是报上面的错误
请高手指教，谢谢！

------解决方案--------------------
如果使用标准的URL是可以这样指定信任https的

Java code

import java.net.URL;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.*;


public class TrustSSL {
    private static class TrustAnyTrustManager implements X509TrustManager {
    
        public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }
    
        public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }
    
        public X509Certificate[] getAcceptedIssuers() {
            return new X509Certificate[]{};
        }
    }
    
    private static class TrustAnyHostnameVerifier implements HostnameVerifier {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    }

    public static void main(String[] args) throws Exception {
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, new TrustManager[]{new TrustAnyTrustManager()}, new java.security.SecureRandom());
        URL console = new URL("https://server:8080/login");
        HttpsURLConnection conn = (HttpsURLConnection) console.openConnection();
        conn.setSSLSocketFactory(sc.getSocketFactory());
        conn.setHostnameVerifier(new TrustAnyHostnameVerifier());
        conn.connect();
        System.out.println(conn.getResponseCode());
    }
}
