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

I received this error while trying to start up an application:

Sun.security.validator.ValidatorException: PKIX path validation failed: 
java.security.cert.CertPathValidatorException:  java.net.UnknownHostException:oscp.thawte.com

The application is behind a closed network and won't ever be able to get to oscp.thawte.com. Is there a java setting that can disable this?

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.

This example on How to disable SSL certificat validation in Java contains a utility class you can copy in your project.

Use cli utility keytool from java software distribution for import (and trust!) needed certificates

Sample:

From cli change dir to jre\bin
Check keystore (file found in jre\bin directory)
keytool -list -keystore ..\lib\security\cacerts
Enter keystore password: changeit
Download and save all certificates chain from needed server.
Add certificates (before need to remove "read-only" attribute on file "..\lib\security\cacerts") keytool -alias REPLACE_TO_ANY_UNIQ_NAME -import -keystore ..\lib\security\cacerts -file "r:\root.crt"

accidentally I found such a simple tip. Other solutions require the use of InstallCert.Java and JDK

On my Mac that I'm sure I'm not going to allow java anyplace other than a specific site, I was able to use Preferences->Java to bring up the Java control panel and turned the checking off. If DLink ever fixes their certificate, I'll turn it back on.

In Axis webservice and if you have to disable the certificate checking then use below code:

AxisProperties.setProperty("axis.socketSecureFactory","org.apache.axis.components.net.SunFakeTrustSocketFactory");

It is very simple .In my opinion it is the best way for everyone

       Unirest.config().verifySsl(false);
       HttpResponse<String> response = null;
       try {
           Gson gson = new Gson();
           response = Unirest.post("your_api_url")
                   .header("Authorization", "Basic " + "authkey")
                   .header("Content-Type", "application/json")
                   .body("request_body")
                   .asString();
           System.out.println("------RESPONSE -------"+ gson.toJson(response.getBody()));
       } catch (Exception e) {
           System.out.println("------RESPONSE ERROR--");
           e.printStackTrace();
       }
   }
