RE: T5: Hibernate

[Jens Reufsteck]

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

Re: T5: Hibernate

[Everton Agner]

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.

I have an existing database, and

Use Hibernate Tools (Eclipse plugin) to generate the entity classes

 I

Declare your DAOs as Tapestry-IoC services and have the Session injected

Re: T5:hibernate @Length validator doesn't work

[Kristian Marinkovic]

hi, 

the beandeditor cannot handle Hibernate annotations.
you have to use the tapestry specific validators.

i think it's a easy-meet problem for newbie(it's me).

@Entity
@Table(name="hello")
public class Hello implements Serializable{
...
 @NotNull(message="{hello.message.notnull}")
 @Length(min=10,max=20)
 @Column(name="message",length=20)
private String message;
...
}

but i can update or create 'hello' record to database with beanEditForm.

Re: t5: hibernate connection string

[Angelo Chen]

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?

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...

Hi,

I use following in hibernate.cfg.xml to connect to database:
 
< 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? 

Thanks,

Angelo

T5 Hibernate listener crash problem - problem with classloader?

[Max Weißböck (info)]

If I configuer  my AuditListener in the hibernate.cfg.xml file like this

		class="net.weissboeck.gimmo.entities.AuditListener"/>


im getting the following error after first acces to database:

[ERROR] TapestryModule.RequestExceptionHandler Processing of request  
failed with uncaught exception: Exception constructing service  
'ValueEncoderSource': Error invoking service builder method  
org 
.apache.tapestry5.services.TapestryModule.buildValueEncoderSource(Map,

event (pre-insert) listener class:  
net.weissboeck.gimmo.entities.AuditListener


Debugging seems to indicate a problem with the classloader.

Has anyone got hibernate listeners working with T5 hibernate module?

This is my AuditListener class (I use a common abstract base entity  
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;

public class AuditListener implements PreUpdateEventListener {

private static final long serialVersionUID = 1L;

@Override
public boolean onPreUpdate(PreUpdateEvent pEvent) {
AbstractBaseEntity entity = (AbstractBaseEntity) 
pEvent.getEntity();
entity.setLastUpdated(new Date());
return false;
}
}

Re: T5 + Hibernate + Hibernate Tools

[Norman Franke]

Yes, that is want I want. For now, what I've done works. Just getting  
the page requires the use of internal classes. I can't even think  
about how to get the component. Once this is included, then I can  
eliminate my hack.

I may wrap ComponentResources into a "holder" class to avoid this,

You can inject the Request and use the ComponentEventLinkEncoder

then use ComponentClassResolver.resolvePageNameToClassName() to  
get the class name.


That seems more icky. Plus, you just get the page path. I think  
getting the actual Page would be better, since another

it now, bug got a NPE when trying to resolvePageNameToClassName.  
So, I'll stick with what I have, I guess.



If there isn't any better way to do it nor a JIRA about it, let's

Sure, feel free. Something along the lines if an injectable Page

You can do this yourself (all you need is to create an account at

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().


This appears to work. Very cool!

T5 + Hibernate + Hibernate Tools

[Norman Franke]

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.

session.update(Object) writes the object to the database, session.lock()  
not. Both associate the object to the session, so use one or the other  
depending on what you need. :)

One solution is to call session.lock(object, LockMode.NONE) before reading  
any property values. It associates the object with the given session, thus

T5: Hibernate/Session question

[James Sherwood]

Hello,

 

I have an application state object(Visit) that is storing a hibernate entity
object.

 

In a page I ask for the visit.object.getchildobject.name and receive this
error:

 

[ERROR] hibernate.LazyInitializationException could not initialize proxy -
the owning Session was closed

org.hibernate.LazyInitializationException: could not initialize proxy - the
owning Session was closed

 

 

Can I not do this from application state objects?

 

Thanks,

Re: T5+Hibernate: Entity class id variables cannot have leading underscores

[SergeEby]

Hi,

This has nothing to do with Tapestry.

You have 2 options:
1) Use the @Column annotation on the _id field
@Id @GeneratedValue @Column(name="id") 
private Long _id;

2) Annotate the accessor methods

T5+Hibernate: Entity class id variables cannot have leading underscores

[Bill Holloway]

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());

T5: Hibernate and services

[Angelo Chen]

Hi,

I have some tapestry-hibernate related questions:

1) if I have two concurrent services(A and B), each has Session injected. do
A and B have their own transaction?

2) I have a table config that has a field 'nextID':

  2.1 IDService has a method 'NextID()' which get the value from
'nextID' and increment it
  2.2 AppendSerivce which uses IDService's NextID to get a number and
assign to a new object, persist it

if I have two instances of UserService(A and B) running, A will be
successful in getting a new ID while B fails because it gets the same ID as
A, any idea how to solve this problem?

Thanks,

Angelo

Re: t5: Hibernate resultset with pagination

[Bill Holloway]

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 
{
protected int _page;

protected int _resultsPerPage;

public PagingResults (int resultsPerPage)
{
_page = 1;
_resultsPerPage = resultsPerPage;
}

public List getCurrentPage () throws Exception
{
List 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 List 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:

http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>

http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>

${pagerInfo}   ${message:first}
 |
<
${message:previous.abbrev}
|
${message:next}
>
|
${message:last}



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

Re: t5: Hibernate resultset with pagination

[Davor Hrg]

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

T5: Hibernate OneToMany: Works in 5.0.11, Fails in 12, 13, 14-SNAPSHOT

[bernatowicz]

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!
Jim

Re: T5 - Hibernate - Transaction confusion

[9902468]

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?

Re: T5 - Hibernate - Transaction confusion

[Angelo Chen]

I think it rolls back only updateValues.  I'd prefer to put several method
calls under one transaction.

T5 - Hibernate - Transaction confusion

[9902468]

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?

Ok. Great gadzooks!  Now I see. Thanks to you and Sven.

(I knew this was going to be obvious once pointed out!)

Quoting 9902468 <[EMAIL PROTECTED]>:



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

its look like, that your Security class is only a helper class
and no page component.

in such classes the @Inject annotation doesnt work

Re: [T5]: Hibernate question - session is null

[9902468]

Check also that you have the mysql-connector-java-5.1.6.jar or similar in
your libraries.

I have the following list:
FieldValidatorSource: DEFINED
  FormDAO: DEFINED
  FormSupport: DEFINED
FreeMarkerService: DEFINED
   FulfillmentDAO: DEFINED
 GoogleMapService: DEFINED
HibernateEntityPackageManager: DEFINED
  HibernateSessionManager: DEFINED
   HibernateSessionSource: DEFINED
HibernateTransactionDecorator: DEFINED
 HiddenFieldLocationRules: DEFINED
 HiveMind: DEFINED
   HttpServletRequest: DEFINED
HttpServletRequestHandler: VIRTUAL
   IgnoredPathsFilter: DEFINED

So that one should be ok. Is the page that you are testing with _really_
calling session.something? Tapestry lazy loads everything so Hibernate is
not really initialized without the call. Can we have the stack trace?

Re: [T5]: Hibernate question - session is null

[Mark Weissenberg]

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

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.

It is.  I notice that when I switch on the mysql log that no attempt  
is ever made to
access the db. Is there any kind of logging I can switch on from  
Tapestry (or maybe
Hibernate) to tell me what is going on?  (I am quite sure the xml file  
is correct and in
the classpath, so I am running out of ideas! Although it must be  
something simple as

these things usually are). session is always null when this code is run.

Code and XML below:


package uk.bl.dlportal.pages.util;

import java.util.List;

import org.apache.tapestry5.ioc.annotations.Inject;
import org.hibernate.Query;
import org.hibernate.Session;

import uk.bl.dlportal.entities.User;


public class Security
{
@Inject
private Session session;

private final static Security security = new Security();


public User authenticate(String userName, String password)
{
System.out.println("SESSION   
"+session);


List result = session.createCriteria(User.class).list();

return null;
}

public static Security getSecurity()
{
return security;
}
}



XML hibernate.cfg.xml is in src/main/resources:

http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd";>


com.mysql.jdbc.Driver
jdbc:mysql://localhost:3306/dlportal
name="hibernate.dialect">org.hibernate.dialect.MySQLDialect

Re: [T5]: Hibernate question - session is null

[9902468]

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(MappedConfiguration
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.

Re: [T5]: Hibernate question - session is null

I'm using Eclipse. The XML config appears in target/classes and  
appears to be in the classpath.


I'm afraid I'm rather new to Tap 5 and also to Hibernate. I'm just  
following what is in the Tutorial. Unfortunately the session is still  
coming out as null.


Is there anywhere I can see that Tapestry is actually using Hibernate

   HibernateSessionSource: DEFINED

Hi,

It's not a technical limitation, but if I recall correctly it mirrors 
the way EJB handles exceptions.


I'm actually surprised this is not configurable...

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.

tcpKeepAlive=true to the jdbc url and a few other things related to
connection pooling) to no avail.  Googling this exception led to a
couple of sites indicating that this problem most likely has to do with
leaving a connection open by not doing a commit on the transaction, even
after queries.  I have faithfully used the @CommitAfter annotation on
all of my updates/deletes, but not on queries.  Should I be using
@CommitAfter even for queries?  The example at
http://tapestry.apache.org/tapestry5/tapestry-hibernate/userguide.html
seems to indicate not (because there is no @CommitAfter on the
findByName method).  Would there be any other reason that a transaction
is left open without a commit?  Has anyone else experienced this
problem, and if so, how did you fix it?

2)   Is there a good reason why @CommitAfter does a commit even when
the method throws a checked exception?  I would like my business
handling methods to rollback the transaction if the method does not
complete normally.  I really want to use a checked exception so the
caller is forced to catch it.

 


Thanks in advance for any help!

Re: [T5] Hibernate integration problems/questions

[9902468]

>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.

[T5] Hibernate integration problems/questions

[Brendan McNichols]

Hi all,

 

I have two questions/issues with tapestry-hibernate integration:

 

1)   In my app, I am getting a "java.net.SocketException: Broken
pipe at java.net.SocketOutputStream.socketWrite0" exception (I am using
MySQL, btw) after the site has been up for a while.  I have tried
several things to fix this (adding autoReconnect=true and
tcpKeepAlive=true to the jdbc url and a few other things related to
connection pooling) to no avail.  Googling this exception led to a
couple of sites indicating that this problem most likely has to do with
leaving a connection open by not doing a commit on the transaction, even
after queries.  I have faithfully used the @CommitAfter annotation on
all of my updates/deletes, but not on queries.  Should I be using
@CommitAfter even for queries?  The example at
http://tapestry.apache.org/tapestry5/tapestry-hibernate/userguide.html
seems to indicate not (because there is no @CommitAfter on the
findByName method).  Would there be any other reason that a transaction
is left open without a commit?  Has anyone else experienced this
problem, and if so, how did you fix it?

2)   Is there a good reason why @CommitAfter does a commit even when
the method throws a checked exception?  I would like my business
handling methods to rollback the transaction if the method does not
complete normally.  I really want to use a checked exception so the
caller is forced to catch it.

 

Thanks in advance for any help!

T5： Hibernate warning

[Angelo Chen]

Hi,

This is an old problem that I was not able to fix, applications runs, but
always get this error

[WARN] AnnotationBinder Package not found or wo package-info.java:
org.bfe.sample.t5.entities

I do have a hibernate.cfg.xml as follow and it works well:


  
com.mysql.jdbc.Driver




  


I do remember that somebody suggests putting a package-info.java in the
entitiies directory, but what needed to be listed?

Thanks,

Angelo

Using Hibernate interceptors with T5-Hibernate

[9902468]

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_?)

Re: T5: Hibernate ValueEncoders

[Filip S. Adamsen]

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. :)

You can create a file called package-info.java (see [1] for details) in your
package directory and the warning should disappear.

it works without workarround if you call any service that does not use

namely almost any service other than Session and HibernateSessionManager.

Re: T5: Hibernate and threaded service

[Angelo Chen]

that's good, i have been using ur work around for the 5.09 version. the
strange thing about this bug is, sometimes it works even without that work
around, but just to be sure, I use the work around all the time, will try
that 5.0.11 when it is released. thanks.

uh,
oh,

it seems I've found a small workarround,
not a definitive fix, but the TreadSource works with it..

Re: T5: Hibernate and threaded service

[Davor Hrg]

this seems to be a JVM bug
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5025230

I tried it in Java 6 and code works just fine

I'll look into it,
an post a jira... also still trying to make a workarround for it

Hi Davor,

That explains my problem,  this happens in 5.0.7 and 5.0.9, never tried it
with 5.0.8

Re: T5: Hibernate and threaded service

[Davor Hrg]

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

Re: T5: Hibernate and threaded service

[Davor Hrg]

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 ?
