I am trying to setup a SSL Socket connection (and am doing the following on the client)
I generate a Certificte Signing Request to obtain a signed client certificate
Now I have a private key (used during the CSR), a signed client certificate and root certificate (obtained out of band).
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 need to create here?
I had a p12 with these components as well and upon using pretty similar code, adding the private key to the keymanager and the root cert from p12 to the trust manager I could make it work. But now I need to make it work without the p12.
EDIT: Stack trace was requested. Hope this should suffice. (NOTE: I masked the filenames)

You need to add the root cert to the keystore as well.
bad_certificate
means:
A certificate was corrupt, contained signatures that did not verify correctly, etc.
[RFC 2246].
