How to pass self-signed certificate and outbound proxy in an app

[Admin]

I'm writing an Jira Plugin for Jira Server 7.13. This plugin will auto notify changes (story/task) to my server (My Server)

My server is using an self-signed certificate, and not in the same local network with Jira Server.

I'm injecting 

com.atlassian.sal.api.net.RequestFactory

to create Request in order to send data to My Server. (Request Factory is supporting me to pass the outbound proxy of Jira Server)

And if My Server's using an self-signed certificate, request from Jira server to My server not work.

Is there any way to  use RequestFactory to pass the outbound proxy and the self-signed certificate too ?

Please somebody can help me !
