Question

我正在连接到Web服务SSL客户端身份验证，我通过以下方式设置密钥库：

System.getProperties().setProperty("javax.net.ssl.keyStore", 
                                  "d:/banking/BankClient/classes/xxcompany/bank/certificate/keystore.jks");
System.getProperties().setProperty("javax.net.ssl.keyStorePassword","password");

调用网络服务时：

GetAccountBalanceResponse resp = services.getAccountBalance(request);

我收到以下错误

WARNING:Cannot connecti with url: https://[redacted] ; reason: javax.xml.soap.SOAPException: Message send failed: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

密钥库包含客户端的私有证书，证书有效，并且在浏览器中使用时工作正常。我该如何解决？

非常感谢。

当签署服务器证书的CA不是众所周知的CA之一或CA的公共证书不在客户端的信任存储中时，会发生此错误。要解决此问题，您必须将CA的公共证书添加到客户端的信任存储区。

有关详细说明，请参阅unable to find valid certification path to requested target和No more 'unable to find valid certification path to requested target'。
