From your controller, you can use the render method,

render returnMessage

(see http://grails.org/doc/2.0.x/ref/Controllers/render.html)

or pass it in a model to a gsp page and then print it from gsp,

return [returnMsg: returnMessage]

....(in .gsp)
${returnMsg}

(see http://grails.org/doc/2.0.x/guide/theWebLayer.html#GSPBasics)
