GWT & Certification

Question

I have GWT, RestyGWT, Widlfly

Standalone.xml

    <security-realm name="AdminSslRealm">
      <server-identities>
       <ssl>
        <keystore path="${env.DBO_PATH_CONFIG}/${env.ADMIN_CONSOLE}" keystore-password="console" /> 
       </ssl>
      </server-identities>
     </security-realm>
    </security-realms>
...
    <https-listener name="httpsAdmin" socket-binding="httpsAdmin" security-realm="AdminSslRealm" enable-http2="true" /> 
...    
    <socket-binding name="httpsAdmin" port="${jboss.https.port:8553}" /> 

So I have 2 question:

1)When I send first JSON I have such error

OPTIONS https://localhost:8443/services/v2/admin/test net::ERR_INSECURE_RESPONSE

Ok I go in browser https://localhost:8443/services/v2/admin/test. and see this picture

After I accept this connection all work fine How do I make the client automatically accept such a connection???

2) After this when I send another JSON I have porblems with CORS

XMLHttpRequest cannot load https://localhost:8443/services/v2/admin/test. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://127.0.0.1:8888' is therefore not allowed access.

Can I solve this problem without the inclusion of CORS on the WiildFy???

if I can help in addressing these issues the certificate? If yes. Prompt how to adjust. On Wildfly I did, but I can not on GWT SuperDev Mode=(
