Make Java accept all certificates over HTTPS

I'm trying to get Java to accept all certificates over HTTPS. This is for testing purposes. No errors were found until the certificate was obtained. However, after adding the following code before my code, I get an HTTPS hostname wrong: should be <sub.domain.com>error. The problem is that my url is that url. How can I solve this problem? Below is the code I've added to try and fix this.

        // 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) {
    }
