我正在尝试建立SSL套接字连接（并在客户端上执行以下操作）

1. 我生成了证书签名请求以获取签名的客户证书

2. 现在，我有一个私钥（在CSR中使用），一个签名的客户端证书和根证书（带外获得）。

3. 我将私钥和签名的客户端证书添加到证书链中，并将其添加到密钥管理器中。和根证书到信任管理器。但是我收到了错误的证书错误。

我很确定自己使用的证书正确。是否也应该将签名的客户端证书添加到信任管理器？试了一下，仍然没有运气。

//I add the private key and the client cert to KeyStore ks
FileInputStream certificateStream = new FileInputStream(clientCertFile);
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
java.security.cert.Certificate[] chain = {};
chain = certificateFactory.generateCertificates(certificateStream).toArray(chain);
certificateStream.close();
String privateKeyEntryPassword = "123";
ks.setEntry("abc", new KeyStore.PrivateKeyEntry(privateKey, chain),
        new KeyStore.PasswordProtection(privateKeyEntryPassword.toCharArray()));

//Add the root certificate to keystore jks
FileInputStream is = new FileInputStream(new File(filename));
CertificateFactory cf = CertificateFactory.getInstance("X.509");
java.security.cert.X509Certificate cert = (X509Certificate) cf.generateCertificate(is);
System.out.println("Certificate Information: ");
System.out.println(cert.getSubjectDN().toString());
jks.setCertificateEntry(cert.getSubjectDN().toString(), cert);

//Initialize the keymanager and trustmanager and add them to the SSL context
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, "123".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(jks);

我需要在这里创建某种证书链吗？
我也有一个包含这些组件的p12，并且使用了非常相似的代码，将私钥添加到密钥管理器中，并将根证书从p12添加到了信任管理器中，我可以使它工作。但是现在我需要使它在没有p12的情况下工作。

编辑：请求堆栈跟踪。希望这足够了。（注意：我屏蔽了文件名）
