How to add Exiting SSL Certificate to tomcat7 ?

I have launched a hourly jasper reports server Image from AWS market place. and I have mapped a sub domain to it and the jasper server works fine and there is no issues in that.

Now I would Like to ass SSL to the server . I already have SSL Certificates from Godady which can support subdomain .

The problem is most of the resources in internet  talks about setting SSL from the begning , ie from creating a CSR . 

Since I already have  SSl certificate I just need to install In tomact 7 server .

Can Any one prove me the Step by step guide to achive this

Thanks in advance .
