| Let's implement a default action. An action is a process which generates a page. It is implemented as a method in a class called a "controller", and a controller can implement several actions.

| We state here that we retrieve a @@C@jResponseHtml@@ object throw the @@M@getResponse()@@ method because of the "html" type as it is indicated. Then we return it to indicate that its content must be returned to the browser. | What this code means is that **index** action of **default** controller retrieves a @@C@jResponseHtml@@ object through the @@M@getResponse()@@ method by passing "html" as argument. And at the end, it returns this response indicating that its content must be returned to the browser. |

| @@C@jResponseHtml@@ has a @@P@body@@ property, which is a @@C@jTpl@@ object. jTpl is a template engine provided by Jelix. In the controller, you see that the @@C@assignZone()@@ method is called. It says: get the content of the 'check_install' zone which is stored in the 'jelix' module, and put this content into the template variable named @@V@MAIN@@. You will see what is a zone later. 'Check_install' zone is a zone which show the main content of the start page. As we don't need it anymore, delete this line so you will have this in your controller: | @@C@jResponseHtml@@ has a @@P@body@@ property, which is a @@C@jTpl@@ object. jTpl is a template engine provided by Jelix. |
