Domain class not accessible in my controller

I'm new to Grails and groovy..

I created a domain class

\grails-app\domain\Abc

Now i created a 开发者_JAVA百科controller in

\grails-app\controllers\myapp\myController

In that, when i created an object it shows error.

def Abc obj = new Abc

The error i got is

unable to resolve class Abc 

I tried to import, but didn't shown there also. Me working in grails 1.3.7 and IntelliJ IDEA 10.0.2

Thank you

Make sure that the location of each class is consistent with the class and package declaration.

I created a domain class

\grails-app\domain\Abc

This class should look like this

class Abc {
    // implementation omitted
}

make sure you have no package declaration, because based on the location, this class should be in the default package (which is actually a bad practice). Ideally you should put this class into a package, then move the source file into a subdirectory of \grails-app\domain that corresponds to the package name.

Now i created a controller in

\grails-app\controllers\myapp\myController

This class should look like this

package myapp
  
class myController {
    // implementation omitted
}

Notice that this class should be named with a lower-case 'm' because that's how the file is named. The standard Java/Groovy naming conventions dictate that classes should begin with a capital letter.

In that, when i created an object it shows error.

def Abc obj = new Abc

There are a couple of problems with this code:

• define the type as either def or Abc but not both
• you're missing some parentheses

Try this instead:

Abc obj = new Abc()

I think you created your domain class & controller class manually. First, your controller should be in the folder controllers, not myapp. Second, you should define a package for both your domain class & controller class, for example:

Domain class:

package myapp

class Book {
...
}

Controller class

package myapp

class BookController {
....
}
