Ok, the problem is the lib version.
So, synchronized all the libraries versions :D

Re: IoC global question
Hi Hugo,
It is exactly that and I didn't understand how to do that. Whatever I test,
it works but it is intrusive.
I re-read the documentation about tapestry-ioc and I still not understand
how to do that. I need an example of webapp with 3 layers around the ioc to
see how tapestry-ioc gives the services instance to the layers.
@Thiago, I read this part but I don't know enought Spring to decide if
tapestry-ioc is really better than Spring. I'm not sure better is the
word. I would prefer more adapt for Tapestry webapp but it's just my
feelling. Just to argue a little more, if it is really better, why the way
to use service injection is different between ioc - MVC and ioc - DAO or ioc
- WS (example, declare a Logger in these all 3 layers and compare the
howto)? Learning a way to do the same thing for each layer is not something
better.
I'm quite sure it can be better than Spring but for some developper, XML
is better than Pojo... just a point of view ;o)
For now, I want to try to use Tapestry-ioc because I think again it is more
adapt to my needs
2007/12/14, Hugo Palma [EMAIL PROTECTED]:
m, i think there's something missing here
If i'm understanding correctly you want tapestry-ioc to manage all your
services (either presentation stuf, db stuff, etc) and you don't want it
to be intrusive. You don't want to reference any tapestry-ioc API inside
you service classes. Does that describe the problem ?
If so, tapestry-ioc can solve your problem really easily.

How do you do yourself? Webapp have usually more than just a MVC layer.
Are
you using the tapestry-ioc only for the MVC layer?
Its seems to me strange for one class having to use @Inject Logger log;
and
for another class Logger log = Logger.getLogger(
ApplicationDaoImpl.class.getName());
2 ways to get the logger in the same application for the same target log
file... Maybe tapestry-ioc should be extended to take care also to the
other
layers.
Maybe I'm totally wrong ;o) so, how should it be coded to respect ioc
pattern between tapestr-ioc and other layers such as Axis2 and
Hibernate3
(for T5 we know ;o) )

Ok I'm going to investigate about that Registry.
So, what's the interrest to use tapestry-ioc instead of Spring ioc? If
I
need my ioc to provide all the services I need, I cannot use
tapestry-ioc
unless I need my other layers to call explicitely the ioc which is not
recommended when you want independant layers working together.
@Hugo, ok I'm going to reread again this part.
2007/12/14, Kristian Marinkovic [EMAIL PROTECTED] :
hi michael,
@Inject only works in Tapestry pages and components (and mixins).
By default Tapestry will use the field type as an id and lookup the
corresponding ioc service.
I assume your Web Service Container was not started by the ioc
container so it runs outside its control. Therefore you have to first
obtain an ioc Registry first and then ask it explicitly for the
service
you want to call. The builder methods are not meant to be called
except by the container :)

IoC global question
Hi,
I have a sort of general question about tapestry-ioc. In fact, I would
like
it to manage all the services of my webapp. In theory it should be the
case,
shouldn't be?
So to provides services to my MVC, no problem the syntax @Inject
MyService
_myService; work perfectly. But, to provide services the same way for
my
Dao
it's different. The same syntax doesn't provide any instance.
I used the tapestry-hibernate and declare my dao as services :
import org.hibernate.Session;
public static UserDao buildUserDao(@InjectService(Session) Session
session) {
return new UserDaoImpl(session);
}
public static UserService buildUserService(@InjectService(UserDao)
UserDao dao) {
return new UserServiceImpl(dao);
}
So my implementation can work. But to use the service, all the callers
have
to know a session object!
Ok, if my caller is a web service, and this web service want to call
the
UserService, @Inject UserService _userService; DOES NOT work and
_userService is null! So I have to call explicitely the builder of my
service FROM the web service... If I do that, I bypass the IoC purpose
Re: IoC global question
Sorry, I'm trying to understand enough well to develop my application
correctly.
So, imagine I have 2 classes ClassA and ClassB from 2 differents layers.
With the IoC in ClassA I should have just a member named ServiceClassB sab
with its getter and setter. ServiceClassB is the interface ClassB
implements.
Then the IoC should have the role to create the ClassB instance and call
classA.setServiceClassB(classBInstance). But, today in my MVC I have to do
that in ClassA :
public class ClassA {
@Inject
ServiceClassB scb;
String onSuccess() {
User user = scb.getAuthenticatedUser(...);
...
}
}
is THE way to use the IoC? This is an example for pages. I think it's ok but
what about this second example, out of pages.
So I need to create a ServiceFactory class.
public class ServiceFactory {
private ServiceClassB scb;
private static ServiceFactory instance;
static {
instance = new ServiceFactory();
}
public static ServiceFactory getInstance() {
return instance;
}
private ServiceFactory() {
scb = new ClassB();
}
public ServiceClassB getSab() {
return scb;
}
}
In a ClassA (not anymore a Tapestry page) I have to do that :
public class ClassA {
private ServiceClassB sab;
public ServiceClassB getSab() { return sab; }
public void setSab(ServiceClassB sab) { this.sab = sab; }
public String aMethod() {
sab = ServiceFactory.getInstance().getUserService();
User user = sab.getAuthenticatedUser(...);
...
}
}
I think this is not IoC. It's just management of services. So my goal is to
make that IoC and something have to call setSab for me, or maybe it's
should be the role of the ServiceFactory?
Regarding what Hugo explained to me, (thanks a lot for your time!) one of
the way is this :
public class UserModule {
public static ServiceClassB build(ServiceUserDao userDao){
ClassB cb = new ClassB(userDao);
return cb;
}
public static ServiceUserDao build() {
UserDao dao = new UserDao();
return dao;
}
}
But I still don't know how to implement ClassA to get my ServiceClassB
instance provided by the IoC. I cannot call the Module without creating a
strong link between ClassA and the IoC, or maybe I have to create this
link?? In my mind, nothing have to call the IoC since it's the IoC who
should call the classes. So I have to say to the IoC which class need it and
for now I just know how to tell the IoC which Services I have and the
dependencies they have.
Or maybe, I'm completely wrong, lol, and in fact the role of IoC is just to
expose services to make them available to the all application and I have in
ClassA to call explicitely the services via their builder in the module and
use them via their interface!
2007/12/17, Hugo Palma [EMAIL PROTECTED]:
Ok, as you can see in the tapestry-ioc documentation there are three
ways of injecting dependencies into services. Only one of them is
actually intrusive, the As parameters to the service implementation
class' constructor (for autobuilt services) one. If you use this way
then you will need to use the Inject annotation in your service
implementation class which will create the dependency you don't want.
So, this leaves you with the other two choices. The As parameters to
the service builder method way has an example right in the beginning of
the Injecting Dependencies sections of the docs. This way your service
class can be completely independent of your IoC container. All the
injection stuff is done in the module builder class. All you have to do
is declare the dependencies in your service build method in the module
builder and use the service class setters to set it's dependencies.
Finally, you can use the As parameters passed to the constructor of the
service's module builder (cached inside instance variables) way. This
in not intrusive also because, again, all the injection stuff is done in
the module builder. Only this time instead of the dependencies being
injected as parameters in the build method they are injected in you
module builder class constructor.
Hope this helps...

Re: IoC global question
Thanks for the TYPO Thiago. Also thanks for the project examples, I'll need
to wait beeing at home to test since the security system here at the office
block them to be download.
Making my ClassA a service? I'm going to try but it means ClassA will be
instanciate only by Tapestry-ioc else I will not have my ServiceClassB
instance (imagine a ClassC needs an instance of ClassA and doesn't care
about services, will I have to make ClassC also a service??).
And what about a custom ServiceFactory singleton class that call the
Registry to get instances and/or be a sort of Global Service referenced in
Tapestry-Ioc?
Again, to create a Service is not a problem, my problem is to call them from
layers without the @Inject which work only from tapestry-core but without
making a link between the layer and tapestry-ioc. The only link I wish is
between tapestry-ioc and layers in this order. ioc knows the layers, but the
layers don't know the ioc, only the service.
Still reading the documentation...

But I still don't know how to implement ClassA to get my ServiceClassB

1) Rename your build() method to buildServiceUserDao.
2) Your ClassA builder method would be something like that:
public static ClassA buildClassA(ServiceClassB serviceClassB) {
ServiceClassB object = new ServiceClassBImplementation();
object.setServiceClassB(serviceClassB);
return object;

Ok, if my caller is a web service, and this web service want to call the
UserService, @Inject UserService _userService; DOES NOT work and
_userService is null! So I have to call explicitely the builder of my
service FROM the web service... If I do that, I bypass the IoC purpose
because I link it directly :
UserService us = AppModule.buildUserService( ... and then I have a
problem!
buildUserService need a UserDao, but my web service doesn't care about
knowing any kind of dao!
So, I should be able to use @Inject MyService _myService; anywhere in my
project and the tapestry-ioc should be able to give instance to all the
class...
Did I (probably) missed something?

Re: CustomFilter
Yes exactly. I want to put the management of session lifecycle and
transaction and commit in a filter.
I don't want to use the Tapestry-hibernate right now since I'm new in
Hibernate and want to integrate it by myself first but ok, I'm going to
follow your clue and take a look at the source of RequestFilter ;)
2007/12/13, Kristian Marinkovic [EMAIL PROTECTED]:
hi michael,
are you trying to implement OpenSessionInView by yourself?
tapestry-hibernate integration does it by default... you can take
a look at the source to see where you can apply filter the tapestry
way :) (see RequestFilter interface in Tapestry for example)

Re: CustomFilter
In fact, I just noticed when I added the tapestry-core-5.0.6.jar in
[tomcat]/common/lib I still have an error but NOT on the same class.
So before it was on :
java.lang.NoClassDefFoundError: org/apache/tapestry/TapestryFilter
After put the tapestry-core jar in the lib of Tomcat :
java.lang.NoClassDefFoundError:
org/apache/tapestry/ioc/services/SymbolProvider
So I added the tapestry-ioc jar and now I have this one :
java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
I imagine I could put all the lib at the server side, BUT, it's not how it
should work!!
It seems the ClassLoader didn't load all the libs when apply the filter,
so
how to force the loading? Why TapestryFilter doesn't have the same problem
than my CustomFilter??
2007/12/12, Michael Bernagou [EMAIL PROTECTED]:

Hi,
I tried to creat emy own filter, a Hibernate filter in fact, like
that
:
[code]
// here the imports... compilation ok
public class HibernateFilter implements Filter {
private TapestryFilter tapestryFilter = new TapestryFilter();
private static Log log =
LogFactory.getLog(HibernateFilter.class);
public void init(FilterConfig filterConfig) throws
ServletException {
log.info(Servlet filter init, now opening/closing a Session
for each request.);
tapestryFilter.init(filterConfig);
}
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {
try {
HibernateUtil.beginTransaction();
chain.doFilter(request, response);
HibernateUtil.commitTransaction();
} catch (RuntimeException e) {
HibernateUtil.rollbackTransaction ();
throw e;
} catch (Exception e) {
HibernateUtil.rollbackTransaction();
throw new ServletException(e);
} finally {
HibernateUtil.closeSession ();
}
tapestryFilter.doFilter(request, response, chain);
}
public void destroy() {
tapestryFilter.destroy();
}
}
[/code]
then I adapt my web.xml like that :
[code]

filter-classorg.hibernate.util.HibernateFilter
/filter-class
/filter
filter-mapping

[/code]
But I get that ERROR at runtime :

TapestryFilter is not loaded by the ClassLoader. Why and how can I
do
that? I tried to test by put the tapestry-core.jar directly in [

Any idea?

Re: Tapestry 5: running tutoriel
Just to say her problem is fixed since she's my collegue. The Eclipse we use here is a custom (crap) Eclipse and jetty and maven plugins do not work normally. She used a normal Eclipse 3.2 WTP with the regular plugins (plus some proxy configuration) and it now it works. 2007/11/14, Jeffrey ai [EMAIL PROTECTED]: Eli, Your mvn command should run without any manual download or settings. I have seen the similar error message before. My problem is caused by a broken maven plugin in my local repository, which is gotten from our incorrectly-configured repository server. I would suggest you to try the following things: * Remove your $HOME/.m2/repository/org/apache/maven/plugins/maven-archetype-plugin or move it somewhere else * If you have $HOME/.m2/settings.xml setup, move it somewhere else * Try to run the command again. This will make you redownload the plugin from maven central repository, which should work. Good luck!

Re: T5.0.6 I'm lost after upgrade T5
I already tried to add the setters, without success. But Itried to access
Home and I got an error regarding my Logger :
My Home.java
public class Home {
...
@Inject
private Logger logger;
String refreshList() {
try {
logger.debug(Processiong refreshList...);
users = applicationService.getUserList().getUserList();
logger.debug(User lists set to page.);
}
catch (PapoException pe) {
logger.error(Failed to get the user list. Nothing set in the page!);
return FAILURE;
}
return SUCCESS;
}
}
And now I have this error :
org.apache.tapestry.internal.services.TransformationException: Error
obtaining injected value for field papo.pages.Home.logger: No service
implements the interface org.apache.log4j.Logger.
I thought Tapestry know everything about logging and in the documentation it
says @Inject private Logger logger; was enought.
Usually I used log4j like that :
private static Logger logger = Logger.getLogger(MyClass.class.getName());
but Howard told me in a old and previous mailing to not use the logging like
that... So, how to use the logger in T5?

Try adding setters to your fields.
Cheers,
Nick.

The error message seems a little strange, but the code above is
injecting a
page called Home. Does that page load correctly if accessed directly?

I replaced my html by tml and placed them in the right place. I upgrade
log4j to get the latest and add the new logging api (to avoid runtime
error).
The thing is really strange...

Re: T5.0.6 I'm lost after upgrade T5
Ok, I got it It was not the right import ;o)
I used this : import org.apache.log4j.Logger; instead of import
org.slf4j.Logger;
Thanks :)

[T5]onSessionClose?
hi, I'm looking for catching the event onSessionClose. In fact, I would like to change the status online to offline of a user whose session is close/lost. Any idea? I thought about a timer at the application level able to get the full list of sessions and make a full update but it seems to me there is maybe another solution. M. -- Michael Bernagou Java Developper
Re: [T5]Global object?
Hi, So I created a singleton class with static field, created at the first session since the last server restart, but I didn't understand why I should use the ASO notation also. I don't need, I think, to store the object in the session, would be redundant, wouldn't be? The object is already available at the page level since I created services to get and update info from this object. Mainly, my UserList store a list of User objects with live fields online/offline, lastIP, lastTimeConnected I don't want to store in my DB (maybe only one of them, if really needed). When the server will restart, new sessions will be created and this creation will update the user status - something like a shared contact list. M. 2007/7/11, Howard Lewis Ship [EMAIL PROTECTED]: You can use the @ApplicationState annotation on a field to mark it as an application-wide state object. It will be stored in the HttpSession. Most of the infrastructure for storing such an object in the ServletContext is available; see the ApplicationStatePersistenceStrategySource service. What's missing is to define a context application state persistence strategy, contribute it to the service, and contribute a ApplicationStateContribution to the ApplicationStateManager service to defne that your ASO belongs in the context, not the (default) session. Again, these are things that will eventually be cooked right into Tapestry (hint: add a JIRA issue) but in the meantime, can be added on an ad-hoc basis. Now that's what I call Dependency Injection! Side note: and that's why we need T5 IoC and not Guice or Spring. Those don't have a concept similar to Tapestry's service configuration / contribution system.
