Certificate validation

Dear java users/developers,

I am trying to validate certificates in JAVA imported from the server
but it seems that my code is wrong.

Could you please let me know where I have made a mistake?

Code is following:

package ssltest;

import java.io.*;
import java.net.*;
import java.util.*;
import javax.net.ssl.*;
import java.security.cert.*;
import java.security.*;
import java.util.regex.*;

public class SSLTest implements HandshakeCompletedListener{

 private int port = 5000;
 private String ip="192.168.0.5";
 private SSLSocketFactory sslSocketFactory;
 private SSLSocket connection;
 private SSLContext sc;
 private PrintWriter outStream;
 private BufferedReader inStream;
   /**
    * @param args the command line arguments
    */
   public static void main(String[] args) {
       // TODO code application logic here
       System.out.println("Start");
       SSLTest e = new SSLTest();
   }

   public SSLTest()
   {
       System.out.println("Connecting to "+ip+" to port "+port);
       connectTo();
   }

   public final void disableCertificates() {
       // Create a trust manager that does not validate certificate
chains
       TrustManager[] trustAllCerts = new TrustManager[]{
           new X509TrustManager() {
