How to deal with SSL Certs to invoke https service in Jar (Spring Batch) Applications

In my application i need to make https call from a batch app (jar).

In order to make sucessfull service call, I definetly need to install certs related to the end point which am pointing to.

How can we install SSL certs and use the same inorder to invoke HTTPS service securely from stand alone jar application (where there is no server involved)?
