For a change, this blog entry is talking about something that exists for a while now :)

Basically, I wanted to setup a demo environment for Grails and GlassFish v3 Prelude on my machine and so decided to dcument the steps along the process. More detailed steps with explanation are available on GlassFish/Grails Getting Started Wiki.

1. Download and unzip GlassFish v3 Prelude.
2. Run GlassFish Update Center to install the Grails module as shown:
   
   

   ~/demos/glassfishv3-prelude >./bin/updatetool The software needed for this command (updatetool) is not installed. If you choose to install Update Tool, your system will be automatically configured to periodically check for software updates. If you would like to configure the tool to not check for updates, you can override the default behavior via the tool's Preferences facility. When this tool interacts with package repositories, some system information such as your system's IP address and operating system type and version is sent to the repository server. For more information please see: http://wiki.updatecenter.java.net/Wiki.jsp?page=UsageMetricsUC2 Once installation is complete you may re-run this command. Would you like to install Update Tool now (y/n): y Install image: /Users/arungupta/demos/glassfishv3-prelude/bin/.. Installing pkg packages. Installing: [pkg:/pkg@1.0.7,0-15.1269:20081008T212532Z, pkg:/python2.4-minimal@2.4.5.0,0-15.1269:20081008T212544Z] Installing updatetool packages. Installing: [pkg:/updatetool@2.0.0,0-15.1269:20081008T212613Z, pkg:/wxpython2.8-minimal@2.8.8,0-15.1269:20081008T212630Z] Registering notifier: Already registered. Initialization complete. Software successfully installed. You may now re-run this command (updatetool).

3. Now run the Update Center again to see a screen as shown below:
   
   

Select "GlassFish support for Grails Framework" and click on "Install" to install the module locally. This creates a new directory "grails" in your GlassFish v3 Prelude directory and install Grails 1.0.4 there.

4. Set environment variables as:
   
   

   ~/demos/glassfishv3-prelude/glassfish/grails >export GRAILS_HOME=~/demos/glassfishv3-prelude/glassfish/grails ~/demos/glassfishv3-prelude/glassfish/grails >export PATH=$GRAILS_HOME/bin:$PATH

   
   
5. Create a template application as:

6. Create a domain specific class as:
   
   

   ~/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore >grails create-domain-class book Welcome to Grails 1.0.4 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails Base Directory: /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore Note: No plugin scripts found Running script /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/scripts/CreateDomainClass.groovy Environment set to development      [copy] Copying 1 file to /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore/grails-app/domain Created Domain Class for Book      [copy] Copying 1 file to /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore/test/integration Created Tests for Book

   
   
7. Add attributes to the domain class by editing "grails-app/domain/Book.groovy" such that it looks like:
   
   

   class Book {   String title   String author }

   
   
8. Create a new controller as:
   
   

   ~/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore >grails create-controller Book Welcome to Grails 1.0.4 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails Base Directory: /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore Note: No plugin scripts found Running script /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/scripts/CreateController.groovy Environment set to development      [copy] Copying 1 file to /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore/grails-app/controllers Created Controller for Book     [mkdir] Created dir: /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore/grails-app/views/book      [copy] Copying 1 file to /Users/arungupta/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore/test/integration Created ControllerTests for Book

9. Edit the generated controller in "grails-app/controller/BookController.groovy" to specify scaffold for the domain class. It looks like:
   
   

   class BookController {     def scaffold = Book }

10. Run the app as shown below:

    Notice, here GlassFish v3 Embedded Server is used for running the application. It is now accessible at "http://localhost:8080/bookstore" and looks like:
    
    
    
    
11. Clicking on the "BookController" shows:
    
    
    
12. Click on "New Book" to add a new book as:
    
    
13. Each entry can be updated/deleted after clicking on "Create" ...
    
    
    
    or "Book List" as shown below:
    
    
    
    

In a matter of few minutes, we created a simple Grails scaffold that runs using GlassFish v3 Embedded Server.
