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

java.security.NoSuchProviderException: no such provider: SunMSCAPI

提问by npocmaka

I have several programs that use SunMSCAPIto read web pages that require an SSL certificate. My code works under Windows XP (32 bit) but does not work under my fresh installation of Windows 7 (64 bit). Here is the piece of code:

我有几个程序SunMSCAPI用于读取需要 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();.... 

And here is the stack trace:

这是堆栈跟踪：

I've tried also following example http://muhammadhamed.blogspot.com/2010/04/accessing-ms-certificate-stores-in-java.htmlbut again received this NoSuchProviderException. My guess is that there is some configuration error but I'm not sure what it is.

我也尝试过以下示例http://muhammadhamed.blogspot.com/2010/04/accessing-ms-certificate-stores-in-java.html但再次收到了这个NoSuchProviderException。我的猜测是存在一些配置错误，但我不确定它是什么。

Here is my JVM information:
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)

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)

I hope somebody will be able to help me :-)

我希望有人能够帮助我:-)

Best regards.

此致。

The J2SE Security pageonly says that the MS CryptoAPI (which SunMSCAPI uses) is only available under Java 6 on 32-bit Windows.

在J2SE安全页面只是说MS CryptoAPI的（这SunMSCAPI用途）仅在32位Windows的Java 6下可用。

Luckily, you can still install the 32-bit JVM on Win64.

幸运的是，您仍然可以在 Win64 上安装 32 位 JVM。
