wiki's ControlAccess sample NPE
Hi all, I've been trying to run the ControlAccess sample on the Tapestry5Howtos site during these 2 days. But I haven't got any luck When Component page = componentSource.getPage(pageName) is called, a NPE is thrown. I'm using Tapestry5.0.15 and tomcat 6.0.18 on windowsXp sp3 Any comment is welcome.

T5.0.6 about Tapestry ioc
I want to implement a service:
public interface Transport {
public void send();
}
public class HttpTransport implement Transport {
private String _address;
private int _port;
private boolean _ssl;
public HttpTransport (String address, int port, boolean ssl) {
_address = address;
_port = port;
_ssl = ssl;
}
public void send) {
// ..
}
}
The parameter of the constructor is from http request. How can I build this
service? I know I can use setters, but I just wanna know how to build a
service using constructor.

Re: T5.0.6 about Tapestry ioc
Hi Chris,
Do you mean that any constructor parameters can be replaced by an object
that provides those parameters?
for an instance, if address, port, ssl are saved in a config file, I have to
pass a ConfigFile object as the parameter of the HttpTransport constructor.
Am I right?
thank you

I'm not sure I understand the constructor parameters. Do you mean they
come from some other object (HttpRequest)? If so, why not just take
HttpRequest as a constructor argument? If you do that then you can auto
bind this service and IoC will know how to create it. If you insist on
the parameters currently listed, then you'll need to have a service
builder method, and inject HttpRequest as an argument into that method.

Re: T5 how to control login state
Thanks a lot everyone. Finally the BasePase way works
But the dispatcher way still doesn't work.

I am a 100% new user for tapestry. Currently I'm working on 5.0.5, but I
got stuck from the just beginning.
I want to implement a kind of user access controller. All the pages,
excepts for the login page, can be accessed by authenticated users only.
users who hasn't passed the authentication will be redirected to the login
page to input their user name and password, and then, if the user name and
password are correct, they will see the page they want
I think this is a very very simple thing to do.But after a few days
working, I am very frustrated.
Firstly, I've tried the onActivate method. My code looks like below:
class BasePage {
@ApplicationState
private UserIdentity _userIdentity;
private boolean _userIdentityExists;
Object onActivate() {
if( !_userIdentityExists)
return Login; //Login is my login page
return null;
}
}
And the I visited http://localhost:8080/myapp(default page is start), I
got a blank empty page. There is nothing at all on the browser. But I can
see the login page when I went to http://localhost:8080/myapp/login
After that I found an article at
http://wiki.apache.org/tapestry/Tapestry5HowToCreateADispatcher. According
to this, I created my dispatcher. But I found ASO doesn't work in my
dispatcher class.
boolean _myIdentityExists always be false.
And if I contribute it use before:PageRender, the dispatch method would
not be invoked then I visit the default start page. I had to use
before:RootPath. Following it my dispatcher class code:
public class SessionController implements Dispatcher {
@ApplicationState
private MyIdentity _myIdentity;
private boolean _myIdentityExists;
public SessionController() {
System.out.println(SessionController: SessionController
created.);
}
public boolean dispatch(Request request, Response response) throws
IOException {
System.out.println(Requesting + request.getPath());
if (! _myIdentityExists ) { // _myIdentityExists always be false
if( _myIdentity == null ) { // here MyIdentity won't be
created
_myIdentity = new MyIdentity(); // I have to
create it by myself.
System.out.println(SessionController: Identity
does not exist.);
response.sendRedirect(login);
return true; // this works, I can see the
login page correctly.
}else
System.out.println(SessionController: Identity
exists.);
}
return false;
}
}
and here is the code in AppModule:
public void
contributeMasterDispatcher(OrderedConfigurationDispatcher configuration,
@InjectService(SessionController) Dispatcher
sessionController) {
configuration.add(SessionController, sessionController,
before:PageRender);
}
before:PageRender and before:Asset do not call dispatch method,
before:RootPath does
I set the session timeout to 1 min in the web.xml.
session-config
session-timeout1/session-timeout
/session-config
After 1 min, I came to the start page.supposedly, I would be redirected to
the login page because session is timeout. But I could still visit the
start page, which meas _myIdentity is still in the Session after the
timeout. Is it a bug or I shouldn't create it by myself?

Re: T5 how to control login state
Thank you Marcus. But I can't understand where to add getters and setters. Do you mean put getters and setters to ASO class or to a certain class where declares an ASO?
