While looking around on interesting projects to wrap i found a java console app (jar file) which is able to create and manage Certificates which can be used in your Server.
It manages Let´s Encrypt Certificates for you.

I thought it may be useful for someone.

ACME Client on Github

Porunov Java ACME Client (PJAC)

An ACME client application for step-by-step SSL certificate management.

PJAC is a CLI management agent designed for use with your own automation tools (ansible, puppet, chef, saltstack, etc.). Also suitable if you want to automate certificate management with your own scripts/programs/crond-jobs etc.).

ACME is a protocol that a Certificate Authority (CA) and an applicant can use to automate the process of verification and certificate issuance.

This application is based on acme4j, a Java ACME library implementation. If you need your own implementation you can use that library.
Supported functions

All functions are executed separately, so you can integrate them seamlessly in your own particular environment.
