Trigger action server side

I would like to trigger the execution of an action-record on the server side, without going through the client side.
Any idea ?

There is action method which is use to call the server side action.

<action-method name="act.hello">
  <call class="com.axelor.my.package.name.Hello" method="myControllerMethod"/>
</action-method>

Call the Controller class

import com.axelor.my.package.name;

public class Hello {

  public void myControllerMethod(ActionRequest request, ActionResponse response) {
   
  }
}

Please review the documentation: Method Action :: Axelor Documentation
