Hello World With Grails

I don't like Java but there is something for real; JVM is stable. Since I don't like Java I thought I could give a try to Grails as it is built on Groovy which runs on JVM. This is a simple tutorial that I explain how to create a very simple Hello World application with Grails. Creating the Application -------- In order to create a Grails application, "grails create-app" command is used. In our case, we will simply type in our terminal: # cd into the directory where you want to create your grails applications. cd ~/projects/grails grails create-app hello Creating the Controller -------- We will create the Grails controller for our application by typing: grails create-controller Hello This command will generate our controller class. Now all we have to do is just typing a text in our controller. Open ../hello/grails-app/controllers/HelloController.groovy. Its content should be like the following. class HelloController { def index = { } } What we are going to do is just rendering a text like this: class HelloController { def index = { render "My First Grails Application" } } Starting the Server -------- The next step is starting the Grails server. grails run-app And point your browser to [http://localhost:8080/hello/hello/index](http://localhost:8080/hello/hello/index) and get greeted! :)
