Grails. Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'

Question

I'm getting started with Grails (3.x) Framework but I got stuck with this error while trying to render domain content to a view:

Error 500: Internal Server Error
URI /hello/index
Class javax.servlet.ServletException
Message: Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'

HelloController.groovy:

package helloworld   
class HelloController {

    def index() {
        def Person persona1 = new Person(firstName: "someone", lastName: "stuck", age: 21)
        [persona:persona1]
    }
}

Person.groovy:

package helloworld

class Person {
    String firstName
    String lastName
    int age
}

you should be able to run something like grails generate-views .. to generate the views. – Gastronome

Answer 1

Make sure that grails-app/views/hello/index.gsp file exists.

This is not the proper solution. Its problem related redirect of file regarding view and model. – Jam

Answer 2

I know that this has an answer, but I thought I'd chime in that I am using Grails 3.0.11 and I found that somethings code like the following will work

render(view: 'index', model: [data: value])

Where as the following will fail with the error above.

def index() {
    [data:value]
}

If I have time, I will poke around more with this and attempt to understand what's going on.

This worked for me with gson views. Does anyone know why just returning the model map doesn't work? – Downtown

Answer 3

if you're using GNU/Linux, check the folder name, files, etc. for case inconsistency.

grails-app/views/Hello/index.gsp
grails-app/views/hello/index.gsp <-- Not the same

GNU/Linux is case sensitive.

grails generate-views - generates GSP views for the given domain class
