Where is your template for the start page (Start.tml)? If I'm notmistaken the archetype sticks it in WEB-INF, which I believe is wrong. Ididn't run into a bug until I contributed a LibraryMapping to thecomponent class resolver...

So is it why my start.tml is not found?? If yes (I'm really not sure), I'm
very surprised about the miss of flexibility T5 have...
For an existing project build in the usual way (Project/src,
Project/webroot), having to change this just for T5 is veru bad...

Well it's a matter of convention

When maven build the project, things are in the place they have to be.

Michael Bernagou a écrit :

No I didn't because I don't understand why the webroot should be in the

src

directory.

About that :
MyProject/src/papo/pages/
MyProject/src/papo/services/

It is what I have but I wrote in my message
MyProject/src/papo.pages/
MyProject/src/papo.services/
instead, just to show it is packages in the point of view of eclipse and
java.

The debug mode show me the Start.java is normally compiled and Tapestry
describe what it did with at runtime :
replacing method, etc...

2007/11/14, Joachim Van der Auwera <[EMAIL PROTECTED]>:

Have you started using the project archetype? This is the easiest way

to

have a correct directory srtucture.

Anyway, I think the paths should be

MyProject/src/papo/pages/
MyProject/src/papo/services/

Kind regards,
Joachim

I have something strange and it made me asking this question :

What are the mandatory project tree elements? (sorry for my english I

don't

now how to write it differently).

So, my project is :

MyProject/src/papo.pages/[all pages such as Start.java and

Start.properties]

MyProject/src/papo.services/[ioc stuff]
MyProject/webroot/[all template such as Start.tml and Start_fr.tml]

But I have this error :

java.lang.RuntimeException Page Start did not generate any markup when
rendered. This could be because its template file could not be

located,

or

because a render phase method in the page prevented rendering.

Start.java:
package papo.pages;

import org.apache.tapestry.annotations.InjectPage;
import org.apache.tapestry.annotations.Persist;
import org.apache.tapestry.ioc.annotations.Inject;

/**
 * Start page of application papo.
 */
public class Start {
  private static final String SUCCESS = "Home";
  private static final String FAILURE = "Start";

  @Persist
  private Login login;
  public Login getLogin() { return login; }
  public void setLogin(Login login) { this.login = login; }

  private String message;
  public String getMessage() { return message; }
  public void setMessage(String message) { this.message = message; }

  @ApplicationState
  private User user;

  @InjectPage
  private Home home;

  @Inject
  private UserService userService;

  @Inject
  private ApplicationService applicationService;

  String onSuccess() {
    try {
      user = userService.getAuthenticatedUser(login.getLogin(),
login.getPassword());
      if (user != null) {
        home.setUser(user);
        UserLite userLite = new UserLite(user.getLogin());
        applicationService.makeOnline(userLite);
        home.setUsers(applicationService.getUserList().getUserList());
      }
      else {
        message = "Login ou Password inconnue. L'identification a

échoué.";

        return FAILURE;
      }
    }
    catch (PapoException pe) {
      message = "La procedure d'identification a rencontré un probleme

!!";

      return null;
    }
    return SUCCESS;
  }
}

It didn't enter in Start.java (I put a debug point) because it was not

able

to "compile" or "find" the Start.tml. Usually, when it found a

compilation

problem, the error message explicitely explain where is the line in

the

template, but in my case, I have only a stack trace.

When I see the Snapshot for the typicall project, there is something

else as

Project tree, and I don't want to follow the architecture. Having the
webroot folder in the src/main and the java in the src/main/java is

not

logic for me.
A web application is not defined like that usually, why to change the

way?

But this is another subject...
