Java send HTTPS request, certificate configuration

With Certificate:

Getting Tomcat SSL (HTTPS) Working
1.Create a certificate keystore containing a single self-signed certificate by executing the Follo   Wing command.   Specify a password value of "Changeit". Note, this command creates both the certificate and the KeyStore

Windows: Enter in the%java_home%/bin/directory:

Keytool-genkey-alias Tomcat-keyalg Rsa-keystore Tomcat.keystore

Generate a Tomcat.keystore file
Unix: $JAVA _home/bin/Input: Keytool-genkey-alias tomcat-keyalg rsa-keystore Tomcat.keystore

Enter in D:/tomcat 5.0/conf directory: Keytool-genkey-alias tomcat-keyalg rsa-keystore Tomcat.keystore
Enter KeyStore Password: Changeit

    [No]:     y

Enter <tomcat> main password
                (if the same as   keystore   password, press ENTER): Here I pressed the carriage return
2.     Copy   The   keystore   file &nb Sp To   catalina_home/conf   copy to Tomcat's Conf
3.     Uncomment   the   "SSL   http/ 1.1   Connector "  entry   in   $CATALINA _home/conf/server.xml.   Your   Entry   should   look   like:
<!--  Define   a   SSL   Coyot E   http/1.1   Connector   on   port   8443  -->
<!---->

<connector port= "8443" maxhttpheadersize= "8192"
                maxthreads= "minsparethreads=" maxsparethreads= "a" of "a"                 enablelookups= "false" disableuploadtimeout= " True "
               acceptcount=" 100 " Scheme= "https" secure= "true"
                Clientauth= "false" sslprotocol= "TLS"
                keystorefile= "/conf/tomcat.keystore"
             truststorefile= "/conf/tomcat.keystore"/>

Save after adding, browse for the following address to visit Tomcat home https://localhost:8443
4. Copy the KeyStore file to the default file location of the Java applications, then run The Java application. Copy to the engineering directory, note that the direct re-engineering below the level of the directory.

5, Java code:

public static void Main (string[] args) throws Exception {
Serverkeys is your own certificate generated by Keytool
System.setproperty ("Javax.net.ssl.trustStore", "Tomcat.keystore");
System.setproperty ("Javax.net.ssl.trustStorePassword", "Changeit");
Connect to HTTPS https://www.sun.com
URL url = new URL ("https://localhost:8443");
HttpURLConnection connection = (httpurlconnection) url.openconnection ();
Connection.setrequestmethod ("POST");
Connection.setdooutput (TRUE);
Connection.setdoinput (TRUE);
System.out.println ("1--conected to" + connection.tostring ());

DataOutputStream dos = new DataOutputStream (Connection.getoutputstream ());
Byte[] rr = new byte[dos.size ()];
Dos.write (rr,0,rr.length);
Dos.flush ();
string ss = new string (RR);
System.out.println ("2-----" +ss);

StringBuffer Outbuff = new StringBuffer ();
BufferedReader in = new BufferedReader (New InputStreamReader (Connection.getinputstream ()));
String Line;
while (line = In.readline ())!= null) {
Outbuff.append (line);
}
In.close ();
System.out.println ("3---Test:" + outbuff.tostring ());
}
