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）下无法工作。 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();....
这里是堆栈跟踪：

我也试过下面的例子http://muhammadhamed.blogspot.com/2010/04/accessing-ms-certificate-stores-in-java.html，但又收到了这个NoSuchProviderException 。 我的猜测是有一些configuration错误，但我不知道它是什么。
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:-)
最好的祝福。
“ J2SE安全性”页面仅说明MS CryptoAPI（使用SunMSCAPI）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。
