i want to set one variable for my entire application and i want to update it whenever a request comes in to a particular action

like 

def action = {
    // some integer variable is already set in application scope with name variable
    variable++
    render(view:"action", model:[variable])
}

In Gsp

<html>
    <body>
        Variable is ${variable}
    </body>
</html>

The output would be

Variable is 1
// on subsequent requests
Variable is 2
and so on….

Thanks

    Is it needs to be one across whole app?

    Its possible by using an (singleton) service, that will handle your value, like:

    class VariableService {
   int value

   synchronized int get() {
      return value
   }

   synchronized int inc(int value) {
      this.value += value
      return this.value   
   }

   synchronized void set(int value) {
      this.value = value
   }
}

    and the use it where you need
