Re: [T5] How to use Services - an example, please
Services are ordinary java classes,
difference is only that some objects you will instantiate
by hand, like StringBuffer or File...
Service is a class for which you let tapestry-ioc to
generate instances. You configure which services
are available in your AppModule and define there
how they are created. If you use bind method
then you supply only the Class and let tapestry fill
in dependancies (through constructor).
If you use buildMyService methods then you require
dependacies by liting them as method parameters
and manualy construct your service.
this is how I can explain it, say if it makes any sense,

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
you must generate hibernate.cfg.xml
have your entities in entities package
add this to your AppModule
public static void
contributeValueEncoderSource(MappedConfiguration,
ValueEncoderFactory> configuration,
Session session
) {
configuration.add(ObjektMitSeqID.class, new
HibernateValueEncoderFactory(session));
}
that is for getting the session
here is my hibernate.cfg.xml
tapestry will add your entities to the session factory if they are in
entities package

Re: T5: Hibernate
The Hibernate configuration element doesn't expect a package with annotated classes as one might assume but expects an annotated package with package-level annotations like @GenericGenerator. So you must explicitly add every annotated class to your Hibernate configuration with a element (or do it programmatically). You might also want to have a look at the Hibernate Entitymanager which apart from being a JPA implementation and thus making your OR mapper exchangeable also gives you the convenience of searching for annotated classes by itself.

Re: T5: Hibernate
Hi Davor,
I read the doc and do the following:
1. put Fruit.java under entities package
2. put hibernate.cfg.xml under resources
3. in the Start.java, I add:
@Inject private Session _session;
String onAction() {
Fruit f = new Fruit();
f.setName("Orange");
f.setPrice(10);
_session.save(f);
_session.close();
return null; }
I got following error:
The content of element type "session-factory" must match

Hi Davor, Thanks, as a newbie, i can't really understand it fully, here is what I got so far: 1) put that tapestry-hibernate.jar in the lib. 2) put all annotated entities in the entities direcotory 3) in your main source: @inject private Session _session; then? what's the Session of this?

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?

[T5] How to use Services - an example, please
Hi,
I've read the manual about services, but don't get it: It's like seeing the
puzzle pieces, but not the whole. Can someone explain it to me please,
especially:
1. How can I use a service to connect to my database? Or should I use
Hibernate?
2. How can I use a service to access the file system? In the demos,
Howard uses a service to access his CD library, and it seems really cool,
but I have no idea how he does it...
More specifically, I had a struts2 MVC webapp which I'm porting to T5. It
had three layers: JSP, which maps nicely to HTML templates, Controllers,
which are myTapestry components and pages, and my DAL, which is still there.
So for every serious class that I need to persist, it has a DAO that does it
for me e.g.:
public WhateverDAO() {
dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(Globals.dbDriver);
dataSource.setUrl(Globals.dbURL);
dataSource.setUsername(Globals.dbUsername);
dataSource.setPassword(Globals.dbPassword);
...
}
public List retrieve(long poId) throws SQLException {
JdbcTemplate jt = new JdbcTemplate(dataSource);
...
}
This does not seem to be the Tapestry way, but can someone show me the true
path :-) A service seems to be the answer... or Hibernate, but I'm not sure
whether that will save me a lot of time.
Thanks,
Erik
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?
Marcus.

Re: T5: Hibernate
ok, pages you know now ... other time you create your classes is inside your module AppModule Tapestry-ioc subsystem is in charge here http://tapestry.apache.org/tapestry5/tapestry-ioc/ read this page to get more information on dependecy injection in general you will need this stuff often http://tapestry.apache.org/tapestry5/tapestry-ioc/service.html since you mention ValueEncoder I belive you are using select Component try this little tutorial I wrote recently http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects generaly, try this page for other tutorials http://wiki.apache.org/tapestry/Tapestry5HowTos Davor Hrg On 9/9/07, Marcus Schmidke <[EMAIL PROTECTED]> wrote: > > 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? > > Concretely, how can I inject a hibernate session into my ValueEncoder? > > Marcus. > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > >
Re: T5: Hibernate
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? Concretely, how can I inject a hibernate session into my ValueEncoder? Marcus. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5 on JDK 1.6 or newer
Unfortunately yesterday we had to switch back to JVM 1.5, as the same symptoms have shown up again. Seems that there is still a problem and JVM 1.6. update 2 is not the solution. -- View this message in context: http://www.nabble.com/T5-on-JDK-1.6-or-newer-tf4324659.html#a12582298 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: Hibernate
not much at the moment, but it's simple to use, factories are created http://tapestry.apache.org/tapestry5/tapestry-hibernate/conf.html you just call @Inject private Session _session; or in the method Especialy if you have DAO's that have Session in constructor than you can configure them efortlessly via AppModule.bind I havent got much time to write you more ... but try it out a bit, it works like a charm Davor Hrg On 9/9/07, Angelo Chen <[EMAIL PROTECTED]> wrote: > > > Hi, > > I searched the list to find a simple tutorial for Tapestry-hibernate, but > couldn't find any, some quite simple, but source code not complete. any > simple code there? anyway, I believe Hibernate can be used directly > without > Tapestry-hibernate module, my question now is, what are the advantages > using > Tapestry-hibernate over using the Hibernate directly?

T5: Hibernate
Hi, I searched the list to find a simple tutorial for Tapestry-hibernate, but couldn't find any, some quite simple, but source code not complete. any simple code there? anyway, I believe Hibernate can be used directly without Tapestry-hibernate module, my question now is, what are the advantages using Tapestry-hibernate over using the Hibernate directly?
