GWT & Certification - gwt

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=(
