Received fatal alert: bad_certificate

I am trying to setup a SSL Socket connection (and am doing the following on the client)

1. I generate a Certificte Signing Request to obtain a signed client certificate

2. Now I have a private key (used during the CSR), a signed client certificate and root certificate (obtained out of band).

3. I add the private key and signed client certificate to a cert chain and add that to the key manager. and the root cert to the trust manager. But I get a bad certificate error.

I am pretty sure I am using the right certs. Should I add the signed client cert to the trust manager as well? Tried that, no luck still.

//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);

Is there some sort of certificate chain that I nee
