java - How to add/use self-signed certificate with Undertow to serve https? -

i've generated self-signed certificate using following command:

subj="/c=us/st=denial/l=home/o=student/cn=data.com"   # -nodes flag provides no passphrase entry openssl req \   -x509 \   -nodes \   -days 365 \   -newkey rsa:2048 \   -keyout privatekey.key \   -out certificate.crt \   -subj "$subj" 

however, i'm not finding examples show how use file certificate.crt undertow.io web server. i'd use certificate create sslcontext can use addhttpslistener undertow api.

i've dug around reading on trustmanagers , keystores, haven't been able find right steps add certificate server serve https. right steps create https server undertow using self-signed certificate?

update intend not deploy this wildfly. it's intended executable jar standing server 'main' via command-line. (a bit more complicated that, there no xml).
