Vaadin
Grails plugin
There is a Grails plugin available that allows Vaadin applications to be run on Grails. See the plugin page for more details. You can also report bugs and add feature requests at the plugin's JIRA page at Codehaus.
Hello World with Vaadin on Grails
This is a simple example to help get you started with the Vaadin Grails plugin.- After installing Grails, execute the following commands at the command line:
grails create-app hello-vaadin cd hello-vaadin grails install-plugin vaadin
- To ensure that the requests to our application get through to your Vaadin app, you'll need to remove the URL mapping for the root context from your URL-mapping file. To do that, just remove the following line from hello-vaadin/grails-app/conf/UrlMappings.groovy
"/"(view:"/index")
- Next, create your implementation of com.vaadin.Application, as you would in your normal Vaadin applicaiton (this example is in Groovy, but Java works fine here too).
package com.mycompany
import com.vaadin.*
import com.vaadin.ui.*
class HelloVaadinApplication extends Application {
void init(){
def window = new Window("Hello Vaadin!")
setMainWindow window
def button = new Button("Click Meee")
window.addComponent button
}
}
- Then point the Vaadin configuration file (hello-vaadin/grails-app/conf/VaadinConfig.groovy) at this new application class, like this:
vaadin {
productionMode = false
applicationClass = "com.mycompany.HelloVaadinApplication"
}
- Now you're ready to run! Execute the following Grails command to start your application.
grails run-app
Then browse to http://localhost:8080/hello-vaadin to see it running!
