TOTD #75: Getting Started with Grails using GlassFish v3 Embedded


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:


  4. 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.
  5. 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

  6. Create a template application as:

    ~/demos/glassfishv3-prelude/glassfish/grails/samples >grails create-app bookstore

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

    class Book {
      String title
      String author
    }

  9. Create a new controller as:

    ~/demos/glassfishv3-prelude/glassfish/grails/samples/bookstore >grails create-controller Book

  7. Edit the generated controller in "grails-app/controllers/HomeController.groovy" such that it looks like:

    class HomeController {

        def index = {
            render "Grails using embedded GlassFish!"
        }
    }
  8. Refresh the web page in the browser and it looks like:



    and clicking on "HomeController" shows the output as:

More details about GlassFish embedding in Grails are available here.

This application can also be deployed on stand-alone GlassFish v3 Technology Preview 2 as explained here. This blog explains how to configure JNDI resources for a Grails application and I plan to explore that in upcoming days.

Once the Servlet engine in Grails is made configurable then GlassFish can be used as the target deployment platform from "run-app" script.

NetBeans 6.5 M1 provide extensive support on Grails application development - details are available here.

Tic Tac Toe using Rails and Grails on GlassFish v3


GlassFish v3 is a modular (OSGi compliant), embeddable (runs in-VM) and extensible (hosts non-Java applications) Application Server. The "extensible" part was demonstrated during JavaOne 2008 by deploying Rails, Grails and Django sample application on GlassFish v3 Technology Preview 2. This blog announces the availability of Rails, Grails and (of course!) Java EE version of the demo code.

The sample application is a simple multi-player game that can be played on Internet and deployed on GlassFish. One of the simplest multi-player game is Tic-Tac-Toe. The complete instructions to checkout, build, deploy and run the sample are available here. The demo can certainly be improved by using the best practices from Rails and Grails and I'll work on them in next few days.

The demo is played in 2 different browser windows (tested on Firefox, Safari & IE). The clicks in the grid on one browser are displayed on the other browser (propagated using GlassFish Comet) and row and column winners are shown.



Some points highlighted by the demo are:
  • GlassFish v3 supports deployment of Rails and Grails applications, in addition to traditional Java EE apps.
  • GlassFish v3 has a completely modular architecture as evident by the pluggability of JRuby/Rails.
  • Features of the underlying GlassFish runtime can be accessed.
    • Any click in the grid is pushed to the endpoint and then propagated to all the clients using GlassFish Comet. So effectively, now you can build Comet-enabled applications using Rails and Grails.
    • Rails application is deployed as a composite application where Serlvet is bundled with the application and accessed from the View.
Check out the demo now!

You can learn about the support of different Dynamic Languages on GlassFish on glassfish-scripting.dev.java.net. Send us feedback on webtier@glassfish.dev.java.net or GlassFish WebTier Forum.

TOTD #31: CRUD Application using Grails - Hosted on GlassFish and MySQL


TOTD #30 explained how to create CRUD application using Grails and hosted using in-built Jetty servlet engine and in-memory HSQLDB database. Jetty and HSQLDB are built into Grails and allows to start easily. You can also use GlassFish and MySQL for deploying your applications in production environment.

This blog entry walks you through the steps of deploying a Grails application on GlassFish and MySQL.
  1. If MySQL is already installed, then download GlassFish v2 UR1. Otherwise you can also Download GlassFish v2 UR1 and MySQL co-bundle from usual Download Page (instructions).
  2. Configure MySQL database
    1. Download MySQL Connector/J 5.1.6 from here.
    2. Extract the bundle and copy "mysql-connector-java-5.1.6-bin.jar" to the "lib" directory of Grails application.
    3. Start MySQL database as:

      ~/testbed/grails-1.0.2/samples/crud >sudo /usr/local/mysql/bin/mysqld_safe --user root --console
      Starting mysqld daemon with databases from /usr/local/mysql/data
    4. Create database by giving the following command:

      ~/testbed/grails-1.0.2/samples/crud >/usr/local/mysql/bin/mysqladmin create crudProd --user root
  3. Configure the Application
    1. Edit "grails-app/conf/DataSource.groovy" to specify MySQL configuration. The updated file looks like (changes highlighted in bold):

      dataSource {
              pooled = false
              driverClassName = "com.mysql.jdbc.Driver"
              username = "root"
              password = ""
              dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
      }
      hibernate {
          cache.use_second_level_cache=true
          cache.use_query_cache=true
          cache.provider_class='org.hibernate.cache.EhCacheProvider'
      }
      // environment specific settings
      environments {
              development {
                      dataSource {
                              dbCreate = "create-drop" // one of 'create', 'create-drop','update'
                              url = "jdbc:hsqldb:mem:devDB"
                      }
              }
              test {
                      dataSource {
                              dbCreate = "update"
                              url = "jdbc:hsqldb:mem:testDb"
                      }
              }
              production {
                      dataSource {
                              dbCreate = "update"
                              url = "jdbc:mysql://localhost/crudProd"
                      }
              }
      }

    2. Being in production, it's recommended to use InnoDB tables instead of MyISAM tables. This can be easily specified by using the dialect as explained here. More details about the contents of "DataSource.groovy" can be found here.
    3. Create a WAR by giving the following command:

      ~/testbed/grails-1.0.2/samples/crud >grails war

      Welcome to Grails 1.0.2 - http://grails.org/

      Done creating WAR /Users/arungupta/testbed/grails-1.0.2/samples/crud/crud-0.1.war
  4. Deploy the WAR file as:

    ~/testbed/grails-1.0.2/samples/crud >~/testbed/glassfish/v3/p2b9/glassfish/bin/asadmin deploy crud-0.1.war
    crud-0.1 deployed successfully
    Command deploy executed successfully.

    The application is now accessible at "http://localhost:8080/crud-0.1" and looks like:


  5. READ - Click on "StateController" and the following page is shown:

  6. CREATE - Click on "New State" and enter the values as shown below:



    and click on "Create" to see the following page:

  7. UPDATE & DELETE - You can click on "Edit" or "Delete" to perform U or D of CRUD or click on "State List" to view the updated list.

Please leave suggestions on other TOTD that you'd like to see. A complete archive is available here.

TOTD #30: CRUD Application using Grails - Hosted on Jetty and HSQLDB


After a simple Grails application, let's create a CRUD application. Such an application allows to perform basic database operations to read table rows from the database, create new rows, and edit and delete existing rows. This blog shows how such an application can be created using Grails, hosted on built-in Jetty servlet engine and use in-memory HSQLDB database for persistence.

A follow-up entry will show how this application can be deployed in production mode on GlassFish and using MySQL database.
  1. Create a Grails application
    1. After Grails download and configuration, create a new application "crud" as:

      ~/testbed/grails-1.0.2/samples >grails create-app crud

      Created Grails Application at /Users/arungupta/testbed/grails-1.0.2/samples/crud
    2. In your project directory, create a domain class as:

      ~/testbed/grails-1.0.2/samples/crud >grails create-domain-class state

      Welcome to Grails 1.0.2 - http://grails.org/
      Licensed under Apache Standard License 2.0
      Grails home is set to: /Users/arungupta/testbed/grails-1.0.2

      Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud
      Note: No plugin scripts found
      Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateDomainClass.groovy
      Environment set to development
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/domain
      Created  for State
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/integration
      Created Tests for State

      This creates "State.groovy" class in "grails-app/domain" directory and looks like:

      class State {

      }

      Add two fields to store state name and the corresponding abbreviation as shown below:

      class State {
              String name
              String abbrev
      }
    3. Change "grails-app/conf/BootStrap.groovy" class to initialize the domain with sample data as shown below:

      class BootStrap {

           def init = { servletContext ->
                new State(name:"California", abbrev:"CA").save()
                new State(name:"New York", abbrev:"NY").save()
                new State(name:"Texas", abbrev:"TX").save()
                new State(name:"Wisconsin", abbrev:"WI").save()
           }
           def destroy = {
           }
    4. Create a new controller as:

      ~/testbed/grails-1.0.2/samples/crud >grails create-controller state

      Welcome to Grails 1.0.2 - http://grails.org/
      Licensed under Apache Standard License 2.0
      Grails home is set to: /Users/arungupta/testbed/grails-1.0.2

      Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud
      Note: No plugin scripts found
      Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateController.groovy
      Environment set to development
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/controllers
      Created Controller for State
          [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/views/state
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/integration
      Created ControllerTests for State

      This generates "grails-app/controllers/StateController.groovy" with the following content:

      class StateController {

          def index = { }
      }

      Replace it with to define a scaffold:

      class StateController {

          def scaffold = State
      }
  2. Start the application using built-in Jetty Servlet engine and in-memory HSQLDB database as shown below:

    ~/testbed/grails-1.0.2/samples/crud >grails run-app

Getting Started with Grails on GlassFish


This blog has published good amount of content on how Ruby-on-Rails applications can be deployed on GlassFish. Grails is another popular MVC-based framework that leverages the Groovy language. Basically, Grails : Groovy :: Rails : Ruby.

Starting today, I plan to start publishing content on Grails and talk about how GlassFish v3 is turning out to be a home for several scripting languages - Ruby/JRuby/Rails, JavaScript/Phobos, Groovy/Grails and more to be added.

This blog shows how to get started with Grails and deploy a simple application on GlassFish v3. Lets go!
  1. Download Grails 1.0.2 (docs, release notes, other builds) and unzip.

    ~/testbed/grails-1.0.2 >export GRAILS_HOME=`pwd`
    ~/testbed/grails-1.0.2 >export PATH=$GRAILS_HOME/bin:$PATH

    On MacOS 10.5, I had to manually set the executable permissions using "chmod +x grails" and then saw the following:

    ~/testbed/grails-1.0.2 >grails

    Welcome to Grails 1.0.2 - http://grails.org/
    Licensed under Apache Standard License 2.0
    Grails home is set to: /Users/arungupta/testbed/grails-1.0.2

    No script name specified. Use 'grails help' for more info

  2. Create & Deploy a Grails HelloWorld:
    1. Create a Grails app "helloworld" as:

      ~/testbed/grails-1.0.2/samples >grails create-app helloworld

      Jetty is used as the development environment server but soon GlassFish v3 can be used, stay tuned on that!

      Anyway, the WAR format is used for deployment. Lets see how this app can be easily deployed as a WAR file on GlassFish v3.
  3. Download GlassFish v3 Preview 2 b08 and unzip.
  4. Create and Deploy WAR
    1. GlassFish certainly supports WAR-based deployment of Grails apps but direct deployment (aka native or directory-based deployment) of Grails applications will be supported soon as well. Anyway, for now, create a WAR file of the application as:

      ~/testbed/grails-1.0.2/samples/helloworld >grails war

      The create WAR file is 18,012,069 bytes.
    2. Start the GlassFish container as:

      ~/testbed/glassfish/v3/p2-b08/glassfish >bin/startserv --verbose
      Apr 10, 2008 11:03:28 AM com.sun.enterprise.admin.launcher.GFLauncherLogger info

      INFO: AdminConsoleAdapter is ready ...
    3. Deploy the WAR file as:

      ~/testbed/grails-1.0.2/samples/helloworld >~/testbed/glassfish/v3/p2-b08/glassfish/bin/asadmin deploy helloworld-0.1.war
      helloworld-0.1 deployed successfully
      properties=(name=helloworld-0.1)
      Command deploy executed successfully.

      The output in the browser now looks like:


  5. Add Controller and Re-deploy
    1. Create a new controller as:

      C~/testbed/grails-1.0.2/samples/helloworld >grails create-controller hello

      Welcome to Grails 1.0.2 - http://grails.org/
      Licensed under Apache Standard License 2.0
      Grails home is set to: /Users/arungupta/testbed/grails-1.0.2

      Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld
      Note: No plugin scripts found
      Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateController.groovy
      Environment set to development
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/controllers
      Created Controller for Hello
          [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/views/hello
           [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/test/integration
      Created ControllerTests for Hello

      and change the controller as shown:

      ~/testbed/grails-1.0.2/samples/helloworld >vi grails-app/controllers/HelloController.groovy

      class HelloController {

             def world = {
                      render "Hello World!"
              }
          //def index = { }
      }
    2. Re-create & re-deploy the WAR as described in bullet # 4. And now "http://localhost:8080/helloworld-0.1" shows the output as shown:



      and clicking on "HelloController" shows the output as:



      The same view is also available at "http://localhost:8080/helloworld-0.1/hello/world" as shown below:


So we deployed a simple Grails application as a WAR on GlassFish v3. Here are some tasks that we are working on:
  • Deploy Grails app on GlassFish v3 using "grails" command (in development environment)
  • Deploy Grails app directly on GlassFish v3 without creating a WAR (in production environment)
  • Seamless integration with NetBeans to provide direct development/deployment to GlassFish
And there is much more, stay tuned!

If you have questions, ask them at GlassFish forum or Users Alias.
