How to bypass certificate checking in a Java web service client

Use Case: There is a web service posted as https://a.b.c.d/zz?wsdl

What i would like to do is to query this URI and IF i get a VALID WSDL, i return a boolean "true" else "false. Now, if i go via Chrome browser to this URL, i would have to manually do an accept on the cert warning, and THEN the WSDL gets downloaded. But how can do this via Java / HttpsURLConnection

import java.net.URL;
import java.io.*;
import javax.net.ssl.HttpsURLConnection;

public class JavaHttpsExample
{
  public static void main(String[] args)
  throws Exception
  {
    String httpsURL = "https://a.b.c.d/zz/V2.0/api?wsdl";
    URL myurl = new URL(httpsURL);
    HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection();
    InputStream ins = con.getInputStream();
    InputStreamReader isr = new InputStreamReader(ins);
    BufferedReader in = new BufferedReader(isr);

    String inputLine;

    while ((inputLine = in.readLine()) != null)
    {
      System.out.println(inputLine);
    }

    in.close();
  }
}

and i get an error:

Exception in thread "main" javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names matching IP address a.b.c.d found at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.fatal(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Unknown Source) at com.sun.net.ssl.internal.ssl.ClientHandshaker.serverCertificate(Unknown Source) at com.sun.net.ssl.internal.ssl.ClientHandshaker.processMessage(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.processLoop(Unknown Source) at com.sun.net.ssl.internal.ssl.Handshaker.process_record(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.net.www.protocol.https.HttpsClient.afterConnect(Unknown Source) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(Unknown Source) at JavaHttpsExample.main(JavaHttpsExample.java:14) Caused by: java.security.cert.CertificateException: No subject alternative names matching IP address a.b.c.d found at sun.security.util.HostnameChecker.matchIP(Unknown Source) at sun.security.util.HostnameChecker.match(Unknown Source) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.checkIdentity(Unknown Source) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.checkServerTrusted(Unknown Source)

i have replaced the real IP with a.b.c.d (of course)
