I assume you mean 'What songs has Jessie J sang?'
This is difficult to answer because I don't know whether you mean the songs on her album, the songs she has released, the songs that she has covered, or all the songs she has ever written. Obviously it would be impossible to tell what songs Jessie J has ever sung, and so I am going to assume that you just mean the ones that she has released. These are in chronological order: (order of time)
Do it Like a Dude
Price Tag
Nobody's Perfect
Who's Laughing Now
Domino
Laserlight
Jessie's next album is said to be coming out in late 2013, and her first single in May 2013.
