One way to handle this is to simply accept any certificate, regardless of what it has in it. Below is a simple program to do just that - it reads a URL and, regardless of what the certificate says, prints out the contents of the URL. Note that this is a bit dangerous to use in a production environment so be careful.

I'll also attach a zip file with a build.xml so that you can build the program with ant.

[code]
package com.xigole.util.ssl;

import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class SelfSignedCertTest {
public static void main(String[] argv) {
if (argv.length != 1) {
System.err.println("usage: SelfSignedCertTest hostname");
System.exit(1);
}

TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}

public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}

public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
System.out.println("authType is " + authType);
System.out.println("cert issuers");
for (int i = 0; i < certs.length; i++) {
System.out.println("\t" + certs[i].getIssuerX500Principal().getName());
System.out.println("\t" + certs[i].getIssuerDN().getName());
}
}
} };

try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}

URL url = null;
try {
url = new URL("https", argv[0], 443, "/");
} catch (MalformedURLException mue) {
mue.printStackTrace();
System.exit(1);
}

try {
URLConnection connection = url.openConnection();

InputStream is = connection.getInputStream();
byte[] buffer = new byte[1024];
int bytesRead = 0;

while ((bytesRead = is.read(buffer)) != -1)
System.out.println(new String(buffer, 0, bytesRead));
} catch (IOException ioe) {
ioe.printStackTrace();
System.exit(1);
}
}
}
[/code]

Note that this is almost the exact same code I posted in [url=http://forums.devshed.com/java-help-9/login-and-download-file-over-https-360178.html]a Devshed thread[/url] but the attachment has a complete build environment too.
