java SSLソケット経由で接続するクライアントとサーバを作成しています。サーバーのみが認証されます（一方向認証）。クライアントがサーバーに接続すると、クライアントはユーザーに1行の入力を求め、サーバーに送信します。KeyManagerFactoryImplを初期化する際のクライアント/サーバプログラムのエラー
私はクライアントを実行するたびに、私は次のエラーを取得する：
Exception in thread "main" java.lang.IllegalStateException: KeyManagerFactoryImpl is not initialized
at sun.security.ssl.KeyManagerFactoryImpl.engineGetKeyManagers(KeyManagerFactoryImpl.java:51)
at javax.net.ssl.KeyManagerFactory.getKeyManagers(KeyManagerFactory.java:289)
at SSLClient.createSSLContext(SSLClient.java:43)
at SSLClient.main(SSLClient.java:50)
私のクライアントコードは次のとおりです。

InputStream in = cSock.getInputStream();
out.write("World".getBytes());
out.write('!');
int ch = 0;
while ((ch = in.read()) != '!')
{
System.out.print((char)ch);
}
System.out.println((char)ch);
}
static SSLContext createSSLContext() throws Exception
{
// set up a key manager for our local credentials
KeyManagerFactory mgrFact = KeyManagerFactory.getInstance("SunX509");
// KeyStore clientStore = KeyStore.getInstance("PKCS12");
// clientStore.load(new FileInputStream("client.p12"), "Password");
// mgrFact.init(clientStore, "password");
// create a context and set up a socket factory
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(mgrFact.getKeyManagers(), null, null);
return sslContext;
}
public static void main(String[] args) throws Exception
{
SSLContext sslContext = createSSLContext();
SSLSocketFactory fact = sslContext.getSocketFactory();
// SSLSocketFactory fact = (SSLSocketFactory)SSLSocketFactory.getDefault();
SSLSocket cSock = (SSLSocket)fact.createSocket("localhost", PORT_NO);
doProtocol(cSock);
}
}
