I have installed the plugin for Jasper 1.6.1 and can see it in my plugin's directory. However according to, http://grails.org/plugin/jasper, it says when you are running your app, test the plugin by going to (app-url)/jasper/demo. When I try that, it doesn't work. I am pretty sure I'm missing something, but the document doesn't say. Please help.
I was able to get it to display with the URL below. Oddly enough, the URL is case sensitive so you have to capitalize the D in jasperDemo...
http://localhost:8080/testGrailsProject01/jasperDemo/demo
