Question

In Browser:

Compilation error

error: cannot find symbol
In /home/william/fmj/app/controllers/Application.java at line 28.

24  public static Result deleteTask(Long id) {

25    return TODO;

26  }

27

28  static Form<Task> taskForm = form(Task.class); 

29

In Terminal:

[error]   static Form<Task> taskForm = form(Task.class);
[error]               ^
[error]   symbol:   class Task
[error]   location: class Application
[error] /home/william/fmj/app/controllers/Application.java:16: error: cannot find symbol
[error]       views.html.index.render(Task.all(), taskForm)
[error]                               ^

[error]   symbol:   class Task
[error]   location: class Application
[error] 3 errors
[error] {file:/home/william/fmj/}fmj/compile:compile: javac returned nonzero exit code

Any Help is greatly appreciated. I copy and pasted the code off of the tutorial (http://www.playframework.org/documentation/2.0.2/JavaTodoList) I’m not sure what’s going wrong and I’d really like to learn this technology!

Answer 1

Apparently you didn’t import Task model into your Application controller

You have 3 solutions:

1. Import each model manually:

   import models.Task;
   

2. import exactly all models into your controller (it will be the best at the beginning, but…)

   import models.*
   

3. Most recommended: Use some IDE which knows when and how to import required packages and classes and suggest you what should be imported (or not) (ie. IntelliJ Idea – just suggestion)
