Is there a java setting for disabling certificate validation? [duplicate]

-Dcom.sun.net.ssl.checkRevocation=false

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

In addition to the answers above. You can do it programmatically by implementing the TrustManager:

TrustManager[] trustAllCerts = new TrustManager[] {        new X509TrustManager() {          public java.security.cert.X509Certificate[] getAcceptedIssuers() {           return null;          }          @Override          public void checkClientTrusted(X509Certificate[] arg0, String arg1)           throws CertificateException {}          @Override          public void checkServerTrusted(X509Certificate[] arg0, String arg1)            throws CertificateException {}          }     };  SSLContext sc=null;  try {   sc = SSLContext.getInstance("SSL");  } catch (NoSuchAlgorithmException e) {   e.printStackTrace();  }  try {   sc.init(null, trustAllCerts, new java.security.SecureRandom());  } catch (KeyManagementException e) {   e.printStackTrace();  }  HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());  // Create all-trusting host name verifier  HostnameVerifier validHosts = new HostnameVerifier() {  @Override  public boolean verify(String arg0, SSLSession arg1) {   return true;  }  };  // All hosts will be valid  HttpsURLConnection.setDefaultHostnameVerifier(validHosts);

However this is not a good practice for production.
