Setting Up Development Environment For Grails on Windows Vista/XP

Filed under: Groovy/Grails, Web — tabrez @ 3:49 pm

Just as Ruby on Rails started to get wide publicity in the media for providing a surprisingly productive web application development framework, many people using other web development technologies suddenly started to wonder if their environment is missing something. Some introspection later, while some tried to add more productive features to their favourite technologies, some others went ahead and committed themselves to create a Ruby on Rails like framework for their own favourite programming language or platform. Where frameworks like TurboGears, Django come close to the model of Ruby on Rails and provided an excellent alternative for the Python programmers, one framework that comes the closest, in my opinion, is the Grails framework, and what good news it is for the Groovy and Java guys looking for an alternative way of developing web applications.

While Grails may yet lack the complete feature set and level of support available for the Ruby on Rails framework, it is very much a stable framework now and currently used by many websites in production environment. Below is the procedure to get everything needed to start creating web applications in Groovy using the Grails framework.

Download and install the latest version of Java SE(currently JDK 6 update 6).
Skip to the next step if you plan to use NetBeans or some other IDE. If you want to work with a text editor and the command prompt, you need to set the following environment variables:
Go to Control Panel -> System -> Advanced System Settings and click the “Environment Variables” button. (Or Control Panel -> System, select the Advanced tab and click the “Environment Variables” button if you are using Windows XP).

Add the path to Java bin directory to the system PATH variable.
Add a new system environment variable called JAVA_HOME and set it to the path to your Java installation directory.

For more details, refer to Sun’s instructions on how to install Java SE.
Download and install the latest stable version of the Groovy windows installer(currently 1.5.6).

Make sure that you install Groovy to a path that doesn’t contain any spaces in it; so you need to remember to change the default path in the installer from “C:\Program Files\Groovy” to something like “C:\groovy”. Also make sure that you select the checkboxes to add Groovy’s directories to system environment variables.

For all the other settings, you can just accept the defaults. To confirm that Groovy is installed and all the environment variables are properly set, run the following command in the command prompt:

C:\> groovy -v
Groovy Version: 1.5.6 JVM: 10.0-b22

If you get an error instead, carefully check again that the environment variables PATH and GROOVY_HOME are properly set.
Repeat the similar process with the Grails installer: Download the latest stable version of the Grails installer and run it.

Unlike the Groovy installer, Grails installer doesn’t create any environment variables, so we have to create them manually. Create a new environment variable called GRAILS_HOME and set it to the Grails installation path.

Also add Grails’s bin directory to the PATH system environment variable:
PATH=%JAVA_HOME%\bin;%GROOVY_HOME%\bin;%GRAILS_HOME%\bin

To make sure that Grails is installed and the environment variables are set properly, run the following command:

C:\Users\tabrez>grails -v

Welcome to Grails 1.0.2 - http://grails.org/
Licensed under Apache Standard Li
Grails home is set to: C:\grails
Now proceed to the next part of this tutorial and create an example “Hello World” web application using Grails framework to validate your Grails installation on Windows operating system.

Can you paste the output of ’set’ command somewhere(e.g. rafb.net/paste) and provide the link here? Open the command prompt and run the set command in it. I am pasting part of the output generated on my machine. Notice the paths set for JAVA_HOME, GROOVY_HOME, GRAILS_HOME and also the paths included in PATH variable.

C:\> set
ALLUSERSPROFILE=C:\ProgramData
APPDATA=C:\Users\tabrez\AppData\Roaming
APR_ICONV_PATH=C:\Program Files (x86)\Subversion\
CLASSPATH=.;C:\Program Files (x86)\Java\jdk1.6.0_

You can also try to see if proper version information is printed by running java -v, groovy -v and grails -v commands. If all the paths are set properly, what error do you get when you try to create a grails application?

I ve solved the problem…

Actuallz windows installer made a dir with name “grails” inside my grails installation folder
for example
C:\Grails\grails
and i had declared GRAILS_HOME =C:\Grails
now i have changed it GRAILS_HOME=C:\Grails\grails
then typed command like grails -v
and everything worked fine
