Problem in HttpsURLConnection

Question

I am trying to make HttpsURLConnection, but I got javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found exception.
I included my code here
If u find anything wrong here, please let me know
System.setProperty("javax.net.debug","all");
System.setProperty("UseSunHttpHandler", "true");
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "my proxy ip");
System.setProperty("http.proxyPort", "80");
System.setProperty("java.protocol.handler.pkgs","javax.net.ssl");
String c_keystore = "madhu.keystore";
System.setProperty("javax.net.ssl.keyStore",c_keystore);
System.setProperty("javax.net.ssl.keyStorePassword","madhu123");
System.setProperty("javax.net.ssl.trustStore",c_keystore);
System.setProperty("javax.net.ssl.trustStorePassword","madhu123");
com.sun.net.ssl.internal.ssl.Provider.install();
java.security.Security.insertProviderAt(new com.sun.net.ssl.internal.ssl.Provider(), 1);
//URL url = new URL("https://myhostname/myfile.jsp");
URL url = new URL(null, "https://myhostname/myfile.jsp", new com.sun.net.ssl.internal.www.protocol.https.Handler());
HttpsURLConnection urlConn; //I tried with HttpURLConnection also
DataOutputStream printout;
BufferedReader input;
String content = "loginname=neonlines&password=password";
System.out.println("OPEN CONNECTION");
urlConn = (HttpsURLConnection)url.openConnection(); //I tried with HttpURLConnection also
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
urlConn.setUseCaches(false);
urlConn.setRequestMethod("POST");
urlConn.setFollowRedirects(true);
/******************** I commented the following lines - No need for me as of now *************
urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
urlConn.setRequestProperty("Content-length", String.valueOf(content.length()));
System.out.println("OUTPUT STREAM");
printout = new DataOutputStream(urlConn.getOutputStream());
printout.writeBytes(content);
printout.flush();
******************** I commented the above lines - No need for me as of now *************/
System.out.println("READ INPUT STREAM");
input = new BufferedReader(new InputStreamReader(urlConn.getInputStream())); //EXCEPTION IN THIS LINE
String str;
String line = "";
System.out.println("PRINTING THE PAGE ");
while((str = input.readLine()) != null) {
     System.out.println(str);
     line += str;
I added the keystore "madhu.keystore" using keytool from x509 (extension cer)
I got the following exception
xecuteThread: '19' for queue: 'weblogic.kernel.Default', SEND TLSv1 ALERT: fatal, description = certificate_unknown

I solved the problem by myself.
I dynamically installed the certificate using TrustManagerFactory and now it's working fine
