Using the JBox2D DebugDraw class for Slick2D it is simple to add debug drawing. Put the below code in your init method:

Slick2DJBox2DDebugDraw debugDraw = new Slick2DJBox2DDebugDraw(gameContainer);
debugDraw.setFlags(DebugDraw.e_shapeBit);
world.setDebugDraw(debugDraw); // Where world is your JBox2D world
