SSLServerSocket problem
I am trying to write a stand alone SSLSocket application. I created the certificate with this line:
keytool -genkey -keystore serverkeys -keyalg rsa -alias chat
The SSLServerSocket gets created with no issues. The server accepts connections from the client without complaint. The problem is when I try and create the IO streams. On the server side this is the exception:
javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown

at secureChatServer.network.ControllerServer.run(ControllerServer.java:50)
at java.lang.Thread.run(Thread.java:595)
here is the relevant code:
public SecureServer(String IPAddress,int port,int backlog)throws SecureChatException
{
try
{
//set up public private key
kStore = KeyStore.getInstance("JKS");
kStore.load(new FileInputStream(KEY), KP);
keyFactory = KeyManagerFactory.getInstance("SunX509");
keyFactory.init(kStore, KP);
sc = SSLContext.getInstance(PROTOCOL);
sc.init(keyFactory.getKeyManagers(), null,null);
//set up server factory and socket
servFactory= sc.getServerSocketFactory();
servSock = (SSLServerSocket)servFactory.createServerSocket(port, backlog, InetAddress.getByName(IPAddress));
...
and
publicvoid run()
{
short val;
int timeout=2000;
while(!stop)
{
try
{
sock = (SSLSocket)servSock.accept();
createIOStreams();
...
}
...
publicvoid createIOStreams()throws IOException
{
read =new ObjectInputStream(sock.getInputStream());
write =new ObjectOutputStream(sock.getOutputStream());
}
On the client side, I get this exception:
secureChat.exception.SecureChatException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

The code:
sock = (SSLSocket)sockFactory.createSocket(Properties.getIPAddress(),Properties.getPort());
write=new ObjectOutputStream(sock.getOutputStream());
read=new ObjectInputStream(sock.getInputStream());
What am I missing?
