Java errors with certrificates, rest template

Question

I have a problem with certificates. Namely, I'm using 2 servers. On the first one is the service which I'm trying to call on the other. Error is:

org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://xxx":no more data allowed for version 1 certificate; nested exception is javax.net.ssl.SSLProtocolException: no more data allowed for version 1 certificate

10:35:08,489 INFO  [stdout] (http-0.0.0.0-0.0.0.0-8443-1)

My code:

@Override
public void changeState(Device device) {            
    RestTemplate restTemplate = new RestTemplate();  

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setContentType(MediaType.APPLICATION_JSON);

    HttpEntity<Device> entity = new HttpEntity<Device>(device, httpHeaders);
    restTemplate.exchange(url, HttpMethod.POST, entity, Void.class);        
}

I have tried this solutions: Disabling SSL Certificate Validation in Spring RestTemplate but it didn't work for me. How can I ignore the certificates?

Try adding this code to the beginning of your method. If so, move the code to the beginning of the application:

java.lang.System.setProperty("javax.net.ssl.trustStore", "NONE");

The server requires to have a certificate attached, but I don't see any ConnectionFactory with it created.

You need to load the certificate material and setup SSL with something like this:

HttpClient sslClient = HttpClients.custom()
                            .setSSLContext(sslContext)
                                          .build();

        ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(sslClient);
        restTemplate().setRequestFactory(requestFactory);
