RE: T5: Hibernate
I remember that I got errors with hibernate, when I had different versions of hibernate core and hibernate annotations combined ( in my case 3.6 with 3.5.6). Downgrading both to 3.5.6 solved it. No idea, what's behind it, I'm not very familiar with hibernate, but I saw you have hibernate with 3.2.2.ga and hibernate annotations with 3.2.1.ga Jens Reufsteck -Original Message- From: robnangle [mailto:robnan...@gmail.com] Sent: Tuesday, November 30, 2010 11:25 AM To: users@tapestry.apache.org Subject: Re: T5: Hibernate Hi, Im trying to get this example but keep getting the same two errors.

Re: T5: Hibernate
Are you using maven and m2eclipse plugin? I don't know if it could help but... Well, right click on the project on eclipse and choose Run as Maven Install . Check if there is any build problem. You could run a Run Maven Clean or Maven Update Dependencies also. Keep an eye on the Maven's Console for any problem. Well, since there's not much info, maybe it could help someway. ___ Everton Agner Ramos 2010/11/30 robnangle robnan...@gmail.com Hi, Yes im running it in eclipse as my ide tomcat as my server mysql as my database -- View this message in context: http://tapestry.1045711.n5.nabble.com/T5-Hibernate-tp2409789p3286828.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

T5 Hibernate
Hello, Can someone point me to the most up-to-date and detailed documentation on using Hibernate with T5 (but not Spring)? Thank you, Benny
Re: T5 Hibernate
Hi Thiago, Thanks for responding, but I was hoping for something a little more detailed. I had visited this link before, but needed more details on things such as configuration and code examples. I have an existing database, and would like to map my models to the existing tables using annotations. I would like to know what I need in terms of configuration and what to inject into my DAO's to get a Hibernate session. If you could give me a few more pointers, I would really appreciate it.

t5: hibernate connection string
Hi, I use following in hibernate.cfg.xml to connect to database: property name=hibernate.connection.urljdbc:mysql://localhost/stock?autoReconnect=true/property This works very well, but it is hard coded, is there a way to put the particular info in a property file, then pick it up when the t5 program is loaded?

Re: t5: hibernate connection string
contribute a HibernateConfigurer to the HibernateSessionSource service. Although I don't quite get why putting the connection string into a properties file is any different than putting it in the xml file...

Re: t5: hibernate connection string
Hi Uli, Thanks for the quick response, leaving it in XML is fine, problem is, the xml file is packaged into a jar, can not find it under the 'ROOT' directory for me to update, any idea putting that hibernate.cfg.xml somewhere else, say WEB-INF?

T5 Hibernate listener crash problem - problem with classloader?
If I configuer my AuditListener in the hibernate.cfg.xml file like this
listener type=pre-insert
class=net.weissboeck.gimmo.entities.AuditListener/
im getting the following error after first acces to database:
[ERROR] TapestryModule.RequestExceptionHandler Processing of request

Debugging seems to indicate a problem with the classloader.
Has anyone got hibernate listeners working with T5 hibernate module?

with alle the technical and audit data for all my entities)
package net.weissboeck.gimmo.entities;
import java.util.Date;
import org.hibernate.event.PreUpdateEvent;
import org.hibernate.event.PreUpdateEventListener;

My only concern is whether any users have already pushed some instance of ComponentResources onto the environment and are counting on a particular instance to be available.

T5 + Hibernate + Hibernate Tools
We have an existing database schema that's rather large. I've used Hibernate Tools to generate the .java entity files, complete with @Entity annotations so Hibernate picks them up automatically. That works very well. Next, I want to use BeanEditForm to edit the tables. I can't really add @Id, @NonVisual, or @Validate to the classes, since they'll be overwritten every time I re-generate the classes when I add or modify a table. What's the best way to do this? Is there some way to do this in a .properties file? Some fancy dynamic class augmentation scheme? I have over 100 tables, so something with minimal maintenance would be best.

Re: T5 + Hibernate + Hibernate Tools
I think I figured it out: @InjectService(PageRenderQueue) private PageRenderQueue pageRenderQueue; Then in buildConstraints: Page page = pageRenderQueue.getRenderingPage(); Messages msgs = page.getRootComponent().getComponentResources().getMessages(); String myValue = msgs.get(myValue); From there, you get the Environment and peek(PropertyEditContext.class) to get the PropertyEditContext from which you can: getPropertyId().

T5+Hibernate: Entity class id variables cannot have leading underscores
To use the simplified page activation context for a hibernate entity page (e.g., onActivate(Person p)...), it looks like the entity class' primary key id field's name must match VERBATIM the text that follows the word get in the getter (and set in the setter, probably). I.e., this won't work: @Id @GeneratedValue private Long _id; public Long getId() This fails because getId is not named get_id. I normally use underscore prefixes for my instance variables. This is failing in HibernateEntityValueEncoder on this line: propertyAdapter = propertyAccess.getAdapter(this.entityClass).getPropertyAdapter(idPropertyName); It looks for an idPropertyName _id and doesn't find one because according to the getter/setter pattern, the name is id. The propertyAdapter is then null which throws an NPE on line 79: Object id = typeCoercer.coerce(clientValue, propertyAdapter.getType()); Bill in Austin -- Without coding you have no product Without testing, no quality Without refactoring, no future - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: t5: Hibernate resultset with pagination
not sure what you are trying achieve exactly paging, table, all can be simply generated even without grid but you'll need to print each column manualy, or dig deeper and use beanModel your self Davor Hrg On Mon, Sep 1, 2008 at 3:32 AM, Angelo Chen [EMAIL PROTECTED]wrote: Hi, I have a need to display some Hibernate resultset with pagination, but I can't use T5's grid. any hint how to do this in T5? thanks.

Re: t5: Hibernate resultset with pagination
Hi Angelo, I achieve custom paging for anything that uses a tapestry
loop (or anything that needs a list per page) starting with this
abstract class:
public abstract class PagingResults T
{
protected int _page;
protected int _resultsPerPage;
public PagingResults (int resultsPerPage)
{
_page = 1;
_resultsPerPage = resultsPerPage;
}
public ListT getCurrentPage () throws Exception
{
ListT pageOfResults = getResultsStartingAt( (_page - 1) *
_resultsPerPage, _resultsPerPage);
return pageOfResults;
}
public void incrementPage ()
{
if (_page lastPage()) _page++;
}
public void decrementPage ()
{
if (_page 1) _page--;
}
public void toLastPage ()
{
_page = lastPage();
}
public int lastPage ()
{
return
(int)Math.ceil((double)getTotalResults()/(double)_resultsPerPage);
}
public void reset ()
{
_page = 1;
}
public int getPage ()
{
return _page;
}
public int getResultsPerPage ()
{
return _resultsPerPage;
}
public abstract ListT getResultsStartingAt (int start, int
numToGet) throws Exception;
public abstract long getTotalResults ();
}
This class' getCurrentPage() method returns a sublist of the total
list for use in the loop, etc. Subclasses of this define the
getResultsStartingAt() and the total number of results. I usually
define subclasses of PagingResults as simple inner classes of my
page/component classes where the services I need are injected.
I have a companion component to this:
public class Pager
{
@Parameter (required = true)
private PagingResults _pagingResults;
@Inject
private Messages _messages;
@Inject
private ComponentResources _resources;
void onActionFromToFirst ()
{
_pagingResults.reset();
}
void onActionFromToPrevious ()
{
_pagingResults.decrementPage();
}
void onActionFromToNext ()
{
_pagingResults.incrementPage();
}
void onActionFromToLast ()
{
_pagingResults.toLastPage();
}
public String getPagerInfo ()
{
String s = ;
int startInd = (_pagingResults.getPage() - 1) *
_pagingResults.getResultsPerPage() + 1;
long endInd = (startInd + _pagingResults.getResultsPerPage() -
1 _pagingResults.getTotalResults()) ?
_pagingResults.getTotalResults() : startInd +
_pagingResults.getResultsPerPage() - 1;
s = startInd + - + endInd + + _messages.get(of) +
+ _pagingResults.getTotalResults();
return s;
}
public boolean getOnFirstPage ()
{
return _pagingResults.getPage() == 1;
}
public boolean getOnLastPage ()
{
return _pagingResults.getPage() == _pagingResults.lastPage();
}
}
The template for this Pager component is simple:
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Strict//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;
div class=peoplepad_pager
xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
${pagerInfo} nbsp; t:actionlink t:id=toFirst
disabled=onFirstPage${message:first}/t:actionlink
|
t:actionlink t:id=toPrevious disabled=onFirstPagelt;
${message:previous.abbrev}/t:actionlink
|
t:actionlink t:id=toNext disabled=onLastPage${message:next}
gt;/t:actionlink
|
t:actionlink t:id=toLast
disabled=onLastPage${message:last}/t:actionlink
/div
In the page/component that uses all this I have a loop (typically)
with source=pagingResults.currentPage. The around the list I place
the pager component which takes the same PagingResults object as a
parameter.
Note this is not setup for Ajax interaction, just standard action
links (Http gets).
Cheers,
Bill

t5: Hibernate resultset with pagination

T5: Hibernate OneToMany: Works in 5.0.11, Fails in 12, 13, 14-SNAPSHOT
Hello. I have 2 entities with a parent-child relationship. Client is the
parent, and Project is the child. In 5.0.11 each Project entity is written
to the (mysql) DB correctly with its client's ID, but in 5.0.12+ each
Project's client_id is zero.
I applied the following source code changes to upgrade from 5.0.11:
* Changed import statements to reflect the renamed tapestry5 package.
In AppModule.java:
* Changed TapestryConstants.SUPPORTED_LOCALES_SYMBOL to
SymbolConstants.SUPPORTED_LOCALES
* Changed TapestryConstants.PRODUCTION_MODE_SYMBOL to
SymbolConstants.PRODUCTION_MODE
No other changes were made. I then changed the Tapestry version in pom.xml
and fired it up with mvn jetty:run.
Are there additional code or config changes that are required to keep this
functionality working in 5.0.12+?
Many thanks for your help!

Re: T5: Hibernate OneToMany: Works in 5.0.11, Fails in 12, 13, 14-SNAPSHOT
you have to add a @CommitAfter in the method where update takes place, or do
a commit, there is a change in default action from commit to abort, it's in
the doc.

T5 - Hibernate - Transaction confusion
Hi,
I'm trying to understand how transactions should be handled with the
@CommitAfter annotation.
I have a normal service interface (FormDAO) that is annotated with commit
afters, but what happens when
Pseudo code:
void onSave() {
formDAO.saveForm(form);
formDAO.updateValues(form, user);
}
and the later call to formDAO throws an exception? Is the first method's
transaction also rolled back, even if both methods have their own
@CommitAfter annotations?
The documentation doesn't specify whether the transaction is rolled back if
there is one successfull @CommitAfter and one failed.
Is the correct approach to wrap multiple service calls in to one and
annotate only this?

Re: T5 - Hibernate - Transaction confusion
I think it rolls back only updateValues. I'd prefer to put several method
calls under one transaction.

Re: T5 - Hibernate - Transaction confusion
I read the source code and it seems that the @CommitAfter really is used to
mark the method and then each method is decorated: thus each method call
gets committed separately. Am I right?

Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign keys? (Change to hibernate config.) You should be able to see that Hibernate starts in the logs and maps User etc. classes. Remember to configure your Log4J or what ever logging u use to debug. I added some lines to log4j.properties to turn on hibernate logging (debug), but I see no output - just the usual Tapestry debug output that I've seen before.

Re: [T5]: Hibernate question - session is null
Yep, Injection works only in page and component classes that live the
ordinary Page or component lifecycle, and are requested from the web. :)
Move the session to a real page and have that util to take the session as
parameter, or even better move your logic to service that a page can use.

Re: [T5]: Hibernate question - session is null
Hi,
I also had some trouble configuring hibernate, my session was also null.
After searching for a while I found this tutorial:
http://linuxboy.javaeye.com/blog/68311
Since I dont use a DAO, my code looks something like the following.
my db entity:
...
import org.hibernate.Session;
@Entity
@Table(name = EVENT)
public class EventDBEntity {
public EventDBEntity() {}
public EventDBEntity(Session session) {_session = session;}
@Transient
private Session _session;
// more stuff here.. methods to access the db
...
in my appmodule.java:
...
public static void bind(ServiceBinder binder)
{
binder.bind(TourDBEntity.class);
}
...
then I call an @Inject on the db-entity:
...
// db entity object
@Inject
private EventDBEntity _dbEntity;
// now tapestry injects the hibernate session in my _dbEntity
...
Hope this helps!
Greetings, Mark

Re: [T5]: Hibernate question - session is null
Tapestry should be quite verbose about hibernate if tapestry is configured to
run in debug mode:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/conf.html
add:
//This is the time in seconds that Tapestry waits before checking if a file
is modified
//Use a big number in production to imporve perfomance.
configuration.add(SymbolConstants.FILE_CHECK_INTERVAL, 1 s); //
600 to production!
// The factory default is true but during the early stages of an
application
// overriding to false is a good idea. In addition, this is often
overridden
// on the command line as -Dtapestry.production-mode=false
configuration.add(SymbolConstants.PRODUCTION_MODE, false);
to your AppModule.java's public static void
contributeApplicationDefaults(MappedConfigurationString, String
configuration) { method.
Also see that your entities are in correct place (same root package as pages
and components, in entities package.)
Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign
keys? (Change to hibernate config.)
You should be able to see that Hibernate starts in the logs and maps User
etc. classes.
Remember to configure your Log4J or what ever logging u use to debug.

It is. I notice that when I switch on the mysql log that no attempt

Tapestry (or maybe
Hibernate) to tell me what is going on? (I am quite sure the xml file

Re: [T5]: Hibernate question - session is null
Thanks for your help, but so far no joy: Quoting 9902468 [EMAIL PROTECTED]: And of course, check that you have Hibernate and hibernate annotation in your libraries, they are NOT included automatically by maven if maven is used. The libraries appear in my repository and appear under sources in the Eclipse Run Configuration. Tapestry should be quite verbose about hibernate if tapestry is configured to run in debug mode: http://tapestry.apache.org/tapestry5/tapestry-core/guide/conf.html add: I placed -Dtapestry.production-mode=false on the command line, which, according to the docs, does the same thing. I see no output about Hibernate at all. It never gets mentioned... Also see that your entities are in correct place (same root package as pages and components, in entities package.) src/main/java/uk.bl.dlportal.entities src/main/java/uk.bl.dlportal.components src/main/java/uk.bl.dlportal.pages looks ok to me. Also perhaps use org.hibernate.dialect.MySQLInnoDBDialect to support foreign keys? (Change to hibernate config.) You should be able to see that Hibernate starts in the logs and maps User etc. classes. Remember to configure your Log4J or what ever logging u use to debug. I added some lines to log4j.properties to turn on hibernate logging (debug), but I see no output - just the usual Tapestry debug output that I've seen before. I'm really stumped... :-( Hibernate never gets called and yet everything appears to be in place. p. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[T5]: Hibernate question
I am following the tutorial at http://tapestry.apache.org/tapestry5/tutorial1/forms2.html but I find that the session (supposedly injected) is null. I'm not sure how to proceed.

Perhaps hibernate.cfg.xml isn't in your runtime classpath? Are you sure your IDE includes it to the output?

Re: [T5] Hibernate integration problems/questions
From the documentation: The transaction will be committed when the method completes normally. The transaction will be aborted if the method throws a RuntimeException. The transaction will be committed if the method throws a checked exception (one listed in the throws clause of the method). And from the main page: Transactions are now aborted (no longer committed) at the end of each request: you must now explicitly commit the transaction if changes are to be saved. So either commit OR rollback should occur. I personally would like to use the model where checked exceptions would cause automatic rollback also. Is this a technical limitation or just chosen procedure? If chosen please elaborate.

Using Hibernate interceptors with T5-Hibernate
Hi! We have few existing Hibernate interceptors and we successfully added those to the Hibernate configuration, but the question is how to inject services / application states to those interceptors. This cannot be done with autobind because (According to Hibernate docs.) Hibernate interceptors must contain parameterless constructors that Hibernate uses when instantiates these classes. If interceptors are used the Hibernate way, then the lifecycle etc. are controlled by Hibernate, and T5 services cannot be used? How to solve this? - 99 Ps. If the answer is to use T5 decorators instead of Hibernate interceptors could someone post a short example how to decorate a service so that all classes implementing specific interface that come to service as parameters are updated to include correct, let's say, update timestamp? Or better yet include it anyway so I can implement it that way in the future :) Thanks! (I did read the IOC docs but couldn't quite picture how to achieve this, as I can target multiple services, but how do I intercept all those entities that go as parameters to service _methods_?) -- View this message in context: http://www.nabble.com/Using-Hibernate-interceptors-with-T5-Hibernate-tp18002714p18002714.html 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 ValueEncoders
Hi,
It means that you can pass Hibernate entities around instead of ids.
Example:
void onActivate(Long id) { User user = session.get(User.class, id); }
Long onPassivate() { return user.getId(); }
becomes
void onActivate(User user) { ... }
User onPassivate() { return user; }
And so forth. Of course this only works if you actually use
tapestry-hibernate. :)

Hi Angelo,
The MyCreate service creates a new record, but doesn't commit until
after MyThread is started.
The MyThread service automatically gets a different Hibernate Session,
and thus can't see the record that hasn't been committed yet by the
other session.
I'm not that familiar with MySQL, but my guess is that the InnoDB engine
supports transactions, while the MyISAM engine doesn't?
If you want this record to be visible across two different threads, you
must commit before you start the second thread. Or perhaps it's simpler
not to use a second thread, and do everything in one session.

Re: T5: Hibernate and threaded service
you should call ThreadCleanupHub.cleanup() at the
each thread you spawn for your self, or tapestry threaded
resources will not get cleaned, and youl make a mem leak.
tapestry uses ThreadLocal to store threaded services like Session,
for example if any part of the code references session(calls a method)
while it is
executed from your thread new session for that thread will be created,
and without calling ThreadCleanupHub.cleanup() inside that thread service

Hi Andy,
Thanks for the quick reply, based on that I modified it as follow:
@Inject
private HibernateSessionManager sessionManager;
Object onSuccess() {
final Long id = create.append();
sessionManager.commit();
new Thread(new Runnable() {
public void run() {
myThread.findMe(id);
}
}).start();
return null;

Re: T5: Hibernate and threaded service
I'm debuggin an example like yours, and although I called ThreadCleanupHub.cleanup() the list of listeners is empty... and HibernateSessionManager is not in it something is very wrong Davor Hrg On Feb 7, 2008 9:35 PM, Davor Hrg [EMAIL PROTECTED] wrote: you did'nt say if the entity is saved to db, if you call commit explicitely, you'll see changes in log, but the way the snippet works is you create entity, you save it to session you change entity... after your task is done, ThreadCleanupHub.cleanup() is called HibernateSessionManager is a listener for that and calls commit then. so your changes are writen to the database at the end, not every time you modify something or, am I missing sth ?
