Hi I installed the new version of the play framework 2.0. Now I am trying to connect to the sample application from the tutorial but something seems not to be working. Here is what i did:
Create the “todolist” application:
play new todolist
play! 2.0, http://www.playframework.org
The new application will be created in /home/evermean/Code/playWorkspace/todolist
What is the application name?
>todolist
Which template do you want to use for this new application?
1 - Create a simple Scala application
2 - Create a simple Java application
3 - Create an empty project
> 2
OK, application todolist is created.
Have fun!
Execute play command:
$ cd todolist
$ play

Execute the run command:

Now I try to connect to the site http://localhost:9000
I get the following output:

I really do not know what to make of that, perhaps someone has an idea on this one. I guess I’m doing something wrong but cannot see where my mistake lies. I hope some can help.
Thanks…
It looks as though the JDK you are using is too old. What version of Java are you using?
