    Default Getting "javax.net.ssl.SSLException" while writing SSL socket program

    Hello, I am a begginer in programimg and I programmed the chat with SSL sockets. I created the certificate via tutorial on this website: Installing and Configuring SSL Support . I use IDE NetBeans and I would like to know the place/folder where the certificate has to be saved. Could you tell me in detail the procedure in Netbeans.
    But momentarily it doesn't work because of the error: javax.net.ssl.SSLException: No available certificate or key corresponds to the SSL cipher suites which are enabled.
    This is the code of server:
    import java.io.BufferedReader;
    import java.io.BufferedWriter;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.OutputStreamWriter;
    import java.util.ArrayList;
    import java.util.logging.Level;
    import java.util.logging.Logger;
    import javax.net.ssl.SSLServerSocket;
    import javax.net.ssl.SSLServerSocketFactory;
    import javax.net.ssl.SSLSocket;

         * @param args the command line arguments
         */
        public static void main(String[] args) {
            try {
                int port = 5000;
                SSLServerSocketFactory serverSocketFactory = null;
                SSLServerSocket serverSocket = null;
                SSLSocket socket = null;
     
                serverSocketFactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
                serverSocket = (SSLServerSocket) serverSocketFactory.createServerSocket(port);
