When I started learning this new technology, I really surprised. I remember how much I struggled when I created my fist web application using Tomcat and JSP. In Grails everything is pretty easy and simple.

I know the application that I am going to explain here is very simple. But I want to share my joy, that’s the only reason I am putting it here. Since it is my first application I won’t like use an IDE.

I wanted to create a web application which can do the CRUD operations on Album details. The Album details include name, artist, release, and copies.

1. I downloaded the binary ZIP from http://www.grails.org/Download
2. Extracted the zip to C:
3. Appended C:\grails-1.1.2\bin" to path variable
4. Created GRAILS_HOME C:\grails-1.1.2
5. I have created a new workspace C:\grails for putting all my Grails application.

Now the platform is ready for me. I have to do only the coding.

1. I have created an application inside C:\grails directory. The command is grails create-app AlbumService
2. Then moved inside AlbumService app. cd AlbumService
3. I have created a controller for my Album Services grails create-controller Album. It created the a controller named AlbumController.groovy inside C:\grails\AlbumService\grails-app\controllers
   
   
   

   
   class AlbumController {
   
   def index = {
    render "
   Grails Hello World
   "
   }
   }
   

   
   
   
4. Next I wanted to know whether my service is up or not. So I edited the AlbumController.I put a Grails Hello World inside the controller.
   
5. Now to run the application I executed the command grails run-app from C:\grails\AlbumService
6. When I tried the url: http://localhost:8080/AlbumService/album yes the welcome page is ready.
7. Now I wanted to create my Album domain class. grails create-domain-class album
8. After that I have edited the file Album.groovy inside C:\grails\AlbumService\grails-app\domain as below. Also I have changed the AlbumController groovy to make def scaffold = true
   

   
   class AlbumController {
   def scaffold = true
   def index = {
   render "
   Grails Hello World
   "
   }
   }
   

   
   

   
   class Album {
   String name
   String artist
   Date release
   Integer copies
   static constraints = {
   }
   }
   

   
   
9. I have executed the grials run-app again and opened the url: http://localhost:8080/AlbumService/album/list. I could see the application there I was able to perform all the CRUD operations!!!
