Grails, JSecurity, and View URL Mapping in JBoss

I've been trying to get my app created in Grails 1.1.1 using the JSecurity plugin to deploy in JBoss 4.2.3.GA. Everything worked fine when I test it using 'grails run-app', but when I deployed my WAR file to JBoss, I got an IllegalStateException any time I tried to access something where I mapped a URL to a view in my UrlMappings.groovy file like this:


It turns out that there's a bug open in the JSecurity plugin: GRAILSPLUGINS-1117. Basically, there's not much explanation as to why, but there is a work-around. Instead of mapping to a view in the UrlMappings file, you map to a controller and action. In the case of the error view, it would look something like this:

"500"(controller:"errors", action:"serverError")

However, there isn't a nice way (that I've found, at least) to map the default "index" view. Instead, you'll either have to create a custom "home" controller that forwards to your generic index page, or map the "/" URL to one of your existing controller actions. In the case of my application, since the main entry point will eventually be through one of the existing controllers anyway, I ended up mapping "/" to that:

"/"(controller:"entryController", action: "list")

With those changes, the app works just fine under JBoss 4.2.3.GA. The JSecurity plugin bug is currently marked as major, so I hope at least it's getting some attention and will be fixed in the near future.
