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.

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
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
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!

Re: IoC global question
Why don't you declare your ClassA as a service too ? This way you could

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...

Re: Adding extra rows to a BeanEditForm / extra columns to a Grid (T5!)
Hello Thiago, Well, in Tapestry 5.0.6, if you just add a column using BeanModel.add, it doesn't show any label, unless you have a added column name-label entry in your app.properties. Don't even have such a property file, but yes - it shows a label (just tried it again to make sure). In your example down there it would be action. beanModel.add(action, null).label(any label you want, including an empty string.); Like I said, when I try giving null, an empty string or a whitespace results in a tapestry exception stating Parameter label was null or contained only whitespace. I've posted a related JIRA, https://issues.apache.org/jira/browse/TAPESTRY-1983, asking for a new parameter in Grid to add new columns without the need to create a BeanModel explicitly as we have to do now. Ah, great! Just added a comment that this would be useful for BeanEditForm too - and voted for it. :) Regad - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Contrib:Table and page parameters
Hm, I think my question was not well formulated. Apologies. I'll try once more! Suppose you want to implement an index that shows all files starting with A, B, etc. My page would show A B C D ... X Y Z and you can click on a letter to show the files starting with this letter in a sortable Contrib:Table. How would I do this? Can somebody lead me on the right track? Thanks! Kaspar On 16.12.2007, at 17:08, Kaspar Fischer wrote: Hi list, How can I tell Contrib:Table to pass on page paremeters? When I click on a table column to sort it, the page that opens does not have the page parameters of the old page anymore! More precisely, my page Page.html uses a paremeter (nodeid) to know what content to display. So in Page.java's pageBeginRender() method I have String nodeIdParam = cycle.getParameter(nodeid); and then I load the data from a database and display a few things in a Contrib:Table. Unfortunately, the link that the Contrib:Table generates in order to sort a column does not contain the value for parameter nodeid: http://localhost:8080/kc/ Page,tableColumnComponent.linkColumn.sdirect?container=Contrib% 3ASimpleTableColumnPagesp=APage%2C% 24SortableTable.table.tableViewsp=SnodeTableTitle So when I click the link, my node does not know what data to load from the database! I think I need to tell Contrib:Table to include the nodeid in the link, right? How can I do this?

Wow, so simple!
Thanks a lot. I feel almost ashamed: of course, informal
properties can be used and they have OGNL-power, too!
Thanks,

Re: Component with mixed functionality?
Thanks, Matt, for your response.
On 16.12.2007, at 02:13, Matt Brock wrote:
The problem is that I don't think your even/odd requirement will
work with
any of the regular Tapestry components. Normally you iterate over a
collection of values (the @For component, for example), and use an
OGNL
expression like class=ognl:(index % 2 == 0 ? 'even' : 'odd') to
determine
whether the row is odd or even. But the problem is, not all of
your rows
are going to be rendered. So what happens when the first row's @If
condition evaluates true, the second row's condition evaluates
false, then
the third evaluates true? You'll end up with two rows both marked
even.
That's exactly what was happening in my case!
The easiest way to do this would be to write your own renderComponent
method. That way you get complete control over the output. This
has the
added advantage of bypassing the OGNL parser. You don't need a
component
definition file (.jwc) or an HTML file, either. Just a single java
class.
Something like this:
MyComponent.java
public abstract class MyComponent extends AbstractComponent {
nbsp;nbsp;@Parameter
nbsp;nbsp;public abstract MyObject getMyObject();
nbsp;nbsp;protected void renderComponent(IMarkupWriter writer,
IRequestCycle cycle) {
// You can also use the writer.begin/writer.attribute way of doing
things,
but this is faster.
nbsp;nbsp;nbsp;nbsp;StringBuffer output = new StringBuffer();
nbsp;nbsp;nbsp;nbsp;output.append(lt;tablegt;);
nbsp;nbsp;nbsp;nbsp;int i = 0;
nbsp;nbsp;nbsp;nbsp;if (getMyObject().getTitle() != null) {
nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;output.append(lt;tr).append
(i % 2 ==
0 ? class=\even\ :
).append(gt;lt;tdgt;).append(getMyObject().getTitle()).append
(lt;/tdgt;lt;/trgt;);
nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;i++;
nbsp;nbsp;nbsp;nbsp;}
nbsp;nbsp;nbsp;nbsp;if (getMyObject().getNextProperty() != null) {
nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;output.append(lt;tr).append
(i % 2 ==
0 ? class=\even\ :
).append(gt;lt;tdgt;).append(getMyObject().getNextProperty
()).append(lt;/tdgt;lt;/trgt;);
nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;i++;
nbsp;nbsp;nbsp;nbsp;}
nbsp;nbsp;nbsp;nbsp;...etc...
nbsp;nbsp;nbsp;nbsp;output.append(
);
nbsp;nbsp;nbsp;nbsp;writer.print(output,true);
nbsp;nbsp;}
}
I get it. -- I finally took Kristian's suggestion as it allowed me
to keep my markup in a HTML-file (even though I don't know whether
the latter is worth it).
Thanks!

Exemple : In pages we have some ognl expression like value=ognl:user.lastname and we change the class's property getLastname() to getName().

Thanks Cyrille I am just telling the obvious, I know, but maybe it's a start: - You could leave getLastname() in your code and make it call getName(). With this wrapper you will not have to change any OGNL expressions. - Make a textual search for lastname in all you files...?

Hi Geoff, This is my first time to try JumpStart on T5. The installation guide is quite straightforward, I went through all things less than 30 minutes.
