  <h3>e502. Disabling Certificate Validation in an HTTPS Connection</h3>

By default, accessing an HTTPS URL using the URL class results in an
exception if the server's certificate chain cannot be validated has
not previously been installed in the truststore.  If you want to
disable the validation of certificates for testing purposes, you need
to override the default trust manager with one that trusts all
certificates.


<pre>    // Create a trust manager that does not validate certificate chains
    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) {
            }
        }
    };
    
    // Install the all-trusting trust manager
    try {
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
    }
    
    // Now you can access an https URL without having the certificate in the truststore
    try {
        URL url = new URL(<font color="#0066ff"><i>"https://hostname/index.html"</i></font>);
    } catch (MalformedURLException e) {
    }
