java client side handshaking using PKCS12 certificate

Question

I am connecting to dc bidden server using following handshaking code

System.setProperty("javax.net.ssl.keyStore",".p12 file path");
System.setProperty("javax.net.ssl.keyStorePassword",keystorePassword);
System.setProperty("javax.net.ssl.keyStoreType",""pkcs12"");

i am able to connect to the first server with this code but for next server tomcat ignore the recent property set so i am not able to connect to next server with same kind of dc bidden server.

Thanks in advance

If by 'connecting https URL' you mean specifically the java.net.URL class and something like new java.net.URL("https://something") .openConnection() which returns an implementation (subclass) of javax.net.HttpsURLConnection here are two examples as I referenced:

static void SO49993912ExampleClientPKCS12 (String[] args) throws Exception {
    FileInputStream fis = new FileInputStream (args[0]);
    KeyStore ks = KeyStore.getInstance("PKCS12"); 
    ks.load (fis, args[1].toCharArray()); fis.close();
    KeyManagerFactory kf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kf.init (ks, args[1].toCharArray());
    SSLContext ctx = SSLContext.getInstance ("TLS"); 
    ctx.init (kf.getKeyManagers(), null /*default TM(s)*/, null);
    // method 1
    HttpsURLConnection conn1 = (HttpsURLConnection) new URL (args[2]).openConnection();
    conn1.setSSLSocketFactory(ctx.getSocketFactory());
    conn1.connect(); System.out.println (conn1.getResponseCode()); conn1.disconnect();
    // method 2
    HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory());
    HttpsURLConnection conn2 = (HttpsURLConnection) new URL (args[2]).openConnection();
    conn1.connect(); System.out.println (conn2.getResponseCode()); conn2.disconnect();
}

However there are lots and lots of other ways of connecting to https (and other) URLs in Java; if you actually meant something else you have to be more specific.
