Antwort: Re: T5: Hibernate
Hi Angelo,
yes ... the service you get from tapestry-hibernate is not mainly just reading
the config. This is simple, you could do it yourself, this is just an
additional benefit.
The main service you get is that sessions and transactions are openend, closed
and committed (hopefully even rolled back in case of exception) at the
right moment during request processing so that you don't have to care about.
Manually commiting a transaction though causes an error when tapestry tries his
automatic commit.
Have fun!
Marcus.

Hi Davor,
Never mind the question, the error comes from a invalid table name, I forgot
it's case senstive. I'd like to now if can use the transaction normally,
like:
Transaction tx = _session.beginTransaction();
List fruits = _session.createQuery("from Fruit f order by

System.out.println(fruits.size() + " found");
tx.commit();
the commit will have an excpetion:

Re: T5: Hibernate
Hi,
it's jta.jar which comes with Hibernate.
In Eclipse, make an additional project containing all jars you have.
So you can always search for any class using Ctrl-Shift-T finding the
right jar for it an add it to the project.
Even better:
You can also make a function less class in your project like follows:
import javax.transaction.Synchronization;
public class Imports {
Synchronization a;
}
For the application without any funktion, just to document all the
ClassNotFoundExceptions you faced. If you get another ClassNotFound,
just add the not-found-class to your "Imports" class. There will be
two errors displayed in Eclipse. Go to the (erroneous) import
statement, Press Ctrl-1 and select "Add jar to project build path".
A very simple way to document which jars are needed and to get them
into the project.
Marcus.

Re: T5: Hibernate
I cannot really tell what the error is, but I am also a beginner and
also started with an existing Hibernate configuration the same way as
you did, so it will be only a small mistake.
One thing I think is important is that Tapestry Hibernate
automatically configures all @Entity classes in the "entities"
package.
So I think you have to remove the "mapping" entry in the
hibernate-config. Either an entity is configured by hibernate config
or programatically (by tapestry in this case), but not both.

Re: T5: Hibernate
Still not in bed .. was too curious about that session thing.
Adding this parameter indeed works - I get some kind of session object
in the contribute method. But what session is this? Is it a session
which is created at this moment (and is already closed when I really
need it) or is it some kind of proxy which always points to the
session which is active in the moment I need it?

Re: T5: Hibernate
Ok ...,
I took a shower which made things much much clearer.
I think I should build and register a BusinessService (just like a
stateless session bean) which encapsulates the Hibernate things. This
Service can have the Hibernate Session injected on some different ways
(just like explained in the document you mentioned), and my value
encoder can make use of this service (I tried to add the service as
parameter to the contributeValueEncoderSource method, and damn! it
worked).
Great, all this seems to work now. Was not too complicated, perhaps
only too late for me. Time to go to bed.
Have a good night!
Marcus.
PS. I'm just thinking about what had happened if I had added a
Hibernate Session parameter to contributeValueEncoderSource's
parameter list? Perhaps this would have worked either?

Re: T5: Hibernate
Yes ... I've read ... parts of it more than once ... but
unfortunately, I do not seem to be clever enough.
I want to write a value encoder which maps Hibernate Entities to their
IDs and vice versa.
I've written
- a HibernateValueEncoder
- a HibernateValueEncoderFactory
- an AppModule containing the following:
public static void
contributeValueEncoderSource(MappedConfiguration,
ValueEncoderFactory> configuration) {
configuration.add(ObjektMitSeqID.class, new
HibernateValueEncoderFactory());
}
(where ObjektMitSeqID is the base class of all of my Hibernate Entities).
This all works fine, no problem, but only as long as I use my own
HibernateUtil to create a Session. But I would prefer using tapestry
to create the Hibernate Session.
Since I don't create a service on my own, but only contribute
configuration to an existing service, I have absolutely no plan how or
where to inject the Hibernate Session.
Perhaps I'm a little bit confused. I don't know. Do you have another hint?

I accidentally found this thread and also tried to get Hibernate integration running. Basically, it runs, but I still know too few about Tapestry basics. @Inject works fine for page components, but how can I make it work in other classes?

T5: @Parameter writes into the field without using the setter method?
Hello, I've written a component which has a parameter field marked as "@Parameter". This works fine, but if I try to do some other work in the setter method for this parameter, I can see that it isn't called. Trying to put @Parameter annotation on the method fails because it's a field annotation. Shouldn't, if present, the setter be used instead of directly writing into the field?

Re: T5: Troubles editing a list of objects
Nick, that was really simple ... and works fine, thank you. But I must admit that I don't understand what I'm doing here (even reading the documentation about loop.volatile did not help me, sorry). What is volatile's default for? I understood so far: Having volatile=default causes serialization of the displayed objects during render. To where? I suppose it's that long long long long invisible field at the beginning of the form? Ok. Later, on request processing, the objects get deserialized from the form, and then, the input values are applied. But what is the intended way to deal with those deserialized objects? They are referenced from nowhere in my code. How can I access the changed values?

T5: Troubles editing a list of objects
Hello all,
the following might be an absolute beginner's error, but since I'm an
absolute beginner, I probably am allowed to have this kind of problem
...
I'm trying to edit a list of values:
class Value {
String name;
String text;
boolean used;
... getters ...
... setters ...
}
class Page {
private @Persist List values;
private Value value; //iterator
... getters / setters ...
... some code to initialize values list ...
}
And the html code:
${value.name}
The page is rendered perfectly. On Submit, the new values are passed
into some Value objects.
But: those Value objects are serialized/deserialized instances of the
original Value objects. While the List still holds the original Value
objects, only copies of them get modified. Result is that my program
code (which works on the list) never sees the modified versions, and
on re-rendering, the old values are displayed again.
What am I doing wrong??
Marcus.

Anybody's developing "object oriented"?
Hello all, I'm in the unlucky situation that I have to give up working with my favourite Web Framework - Apple's WebObjects - in favor to something that is more J2EE-homed and more open source (seems that WO will be this too at some time, but even then - no chance) and more portal-ready. Perhaps I will be forced to use JSF, but if I have some good arguments, perhaps there is a small chance to push some other framework - Tapestry, for example. I've experimented a little with JSF and was totally disappointed. The main things I missed comparing to my previous-millennium-framework were: - working iterators, especially with a dynamic number of input fields and buttons in the iterator body - object oriented developing - component oriented developing "Object oriented developing" means: imagine a list of objects I want to display in a list box. I want to write a method which extracts a displayable string, but that's already all. I think it's the framework's problem to generate HTML-able VALUE-Strings and to convert those strings back to objects. My previous millennium framework had absolutely no problem doing this for me - it simply numbered the elements and the only thing I had to do is to make sure that the Collection of objects was the same at the beginning of the next action request. Frustrated like this I had a look at Tapestry, which was invented in memory of WebObjects. Most of my JSF-problems seem to have a Tapestry-solution, that's fine. But, oh no, what is this "ValueEncoder"-thing??? Don't say it is what I'm afraid of it might be ... Any comments?
