Question

我有几个程序使用SunMSCAPI来阅读需要SSL证书的网页。我的代码在Windows XP（32位）下运行，但在我全新安装的Windows 7（64位）下无效。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：

我也尝试过关注示例http://muhammadhamed.blogspot.com/2010/04/accessing-ms-certificate-stores-in-java.html，但又收到了此NoSuchProviderException。我的猜测是有一些配置错误，但我不确定它是什么。

这是我的JVM信息：
java version "1.6.0_23"
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)

我希望有人能够帮助我： - ）

最好的问候。

J2SE Security page仅表示MS CryptoAPI（SunMSCAPI使用）仅在32位Windows上的Java 6下可用。

幸运的是，您仍然可以在Win64上安装32位JVM。

java.security.NoSuchProviderException：没有这样的提供者：SunMSCAPI
