设置Jmeter来执行HTTPS。

I am using a jmeter 2.7 for my load testing. When we started of the urls to use were simple http. Now we have moved to HTTPS. Can some one tell me how to enable ssl in jmeter? I did go through the jmeter manual and un-commented the SSL portions (all SSL lines now :( ) from system.properties and also have changed the protocol to be HTTPS under Http Request sampler -> Http Request and still no success.
