How to find the physical path to a GSP file in a deployed grails application

Question

I need to know the physical path of the GSP grails file.

My requirement is that I want to create a new layout file at runtime and use it in the application.

I was able to achieve this without problems when the application runs on the dock (grails run-app), however, when I deploy the application to Jboss, the path to the file must be changed.

So, ideally, I would like to find out at runtime, using some magic utility, the path to a specific GSP (say, the main.gsp layout file), and I need to create a new layout in the same directory that main.gsp lives in.

Any pointers?

Below is the groovy code for finding the path to the layout folder in the production environment (for example, when deployed as war on jboss):

import org.codehaus.groovy.grails.commons.ApplicationHolder ... File layoutFolder = ApplicationHolder.application.parentContext.getResource("WEB-INF/grails-app/views/layouts").file def absolutePath = layoutFolder.absolutePath println "Absolute Path to Layout Folder: ${absolutePath}" File newLayoutFile = new File(layoutFolder, "foo.gsp") 

To use the newly created layout, you probably need to restart the web application or container because the views are processed in production mode.

There is definitely ...

 grailsApplication.parentContext.getResource("WEB-INF/grails-app/views/path/to/my.gsp").file.toString() 

Outside of controllers (e.g. bootstrap)? Just enter ..

 def grailsApplication

In controllers you can use

 grailsAttributes.getApplicationContext().getResource("/relative/path/").getFile().toString()
