java.security.NoSuchProviderException : no such provider: SunMSCAPI

Question

我有几个程序使用 SunMSCAPI 来读取需要 SSL 证书的网页。我的代码在 Windows XP(32 位)下工作，但在我全新安装的 Windows 7(64 位)下不起作用。这是一段代码:

System.setProperty("javax.net.ssl.keyStoreProvider", "SunMSCAPI");
System.setProperty("javax.net.ssl.keyStoreType", "WINDOWS-MY");
System.setProperty("javax.net.ssl.trustStoreProvider", "SunMSCAPI");
System.setProperty("javax.net.ssl.trustStoreType", "WINDOWS-ROOT"); 
System.setProperty("proxyHost", "proxy");
System.setProperty("proxyPort", "8080");

URL url = new URL(TEST_URL);
try {
    HttpsURLConnection httpsCon = (HttpsURLConnection) url.openConnection();.... 

这是堆栈跟踪:

我也试过下面的例子 http://muhammadhamed.blogspot.com/2010/04/accessing-ms-certificate-stores-in-java.html但再次收到此 NoSuchProviderException。我的猜测是存在一些配置错误，但我不确定是什么。

这是我的 JVM 信息:
Java 版本“1.6.0_23”
Java(TM) SE 运行时环境(build 1.6.0_23-b05)
Java HotSpot(TM) 64 位服务器 VM(内部版本 19.0-b09，混合模式)

我希望有人能够帮助我 :-)

最好的问候。

J2SE Security page只说 MS CryptoAPI(SunMSCAPI 使用)仅在 32 位 Windows 的 Java 6 下可用。

幸运的是，您仍然可以在 Win64 上安装 32 位 JVM。
