checkout the example given there...
it gives you list of basic libraries which you need if are thinking to download all of them not to worry please download hibernate core library from the below link you'd be getting hibernate3.jar along with all the dependecies in there.
http://sourceforge.net/project/downloading.php?group_id=40712&use_mirror=superb-east&filename=hibernate-3.2.5.ga.zip&70356791
Hope that might help :)

Can we select few columns through criteria query?
If yes plz give me an example how to do it.shakti wrote:
can u give me a small exampleWell, here's someone doing essentially what you want: http://stackoverflow.com/questions/1618394/use-fewer-columns-on-sql-query-through-hibernate-projections-on-entity-with-many
Note how he's also being told that using the criteria API for this is stupid. -
Hi
Yesterday i posted one query regarding hibernate.No one replied me with correct answer.So i am posting it again.i am using hibernate to populate data from database to my table control.The table columns contains textfields.i am using objectlistdataprovider to display the list of values from hibernate bean.My problem is i can update the values in the table displayed on UI(as it is a textfield).but i am not able to get the values from textfield inside table.i wan to know how can i get the values back from textfield inside a table control so tht i can update tht back to database using hibernate. i am not using spring here
Thanks
ShameerYou should be able to get back the data from the text field. In hibernate, you get the List of data from the hibernate session. Using that List, you must be creating the ListDataProvider. But when the table is submited after the data is entered in the textfield only the ArrayListDataProvider is modified. You need to get the data from the List inside the data provider and comit it back using hibernate session. One of our ineterns was able to do this for her MS project.

Unable to read one-to-many relations using Hibernate
Hi,
I am trying with a very simple one-to-many relationship. When I am storing the objects, there are no problems. But when I am trying to read out the collection, it says invalid descriptor index. Please help.

Debug level Hibernate log excerpt:
Included in the above description.That's not the right mapping for the 1:m relationship in Hibernate.
First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
Second, you'll find the proper syntax for a one-to-many relationship here:
http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html#tutorial-associations
See if those help.
The tutorial docs for Hibernate are quite good. I'd recommend going through them carefully.

Hibernate OR EclipseLink...Which is best with Weblogic and Oracle DB?
Hi All,
In my company, we are using Oracle DB and Weblogic application server. So in the process to upgrade or switch to new ORM, we shortlisted two options - Hibernate and EclipseLink.
I gathered following summary regarding both ORMs -
Hibernate:
1. When you need to train people, like we are going to do next week – most of the companies have Hibernate experts.
2. When you hire new developers, most of them come with specific Hibernate experience.
3. When you need to consult with experts, both in the internet or consultants, you have LOTS of options. Endless forums and communities all regarding Hibernate.
4. Hibernate is an open source which has a huge community. This means that it will be improved all the time and will push the ORM market forward.
5. Hibernate is an open source which means you have the code to handle, and in case needed, fit it to your needs.
6. There are lots of plugins to Hibernate, such as validations tool, audit tools, etc. These becomes standard as well and dismiss you from impl. things yourself.
7. One most important thing with ORM tool, is to configure it according to your application’s needs. Usually the default setting doesn’t fit to your needs.
For that sake, when the market has a huge experience with the tool’s configuration, and lots of experts (see point 1 and 3) – most of chances you will find similar cases and
lots of knowledge about how to configure the tool and thus – your application.
EclipseLink:
1. Fully supported by Oracle. Hibernate no. In case of pb, it could be cumbersome to prove that it is a pure Weblogic one. Concretely, we will have to prove it (waste of time and complexity).
2. Eclipse link is developed by Oracle and the preferred ORM in the Weblogic /Oracle DB world.
3. Even if at a certain time EclipseLink was a bit late compared to Hibernate (feature), EclipseLink evolved very fast and we can consider now that they close the gap.
4. No additional fee as soon as you have Weblogic license. You will need to pays additional fee if you want some professional support on Hibernate.
5. We are currently relying on Hibernate for our legacy offer and are facing pb in second level cache (JGroups). Today, we are riding off this part!. Consequences are limitation in clustering approach (perf)
6. On EclipseLink side we do succeed to manage first and second level cache in a clustering approach.
7. Indeed Hibernate is open source, so you can imagine handling it. In reality, the code is so complex that it is nearly impossible to modify it. Moreover as it is LGPL, you need to feedback all the modified sources to the community systematically.
8. All tests performed by Oracle concerning Weblogic are using EclipseLink. Moreover, Oracle says that some specific optimizations are done to manage Oracle DB.
9. Hibernate comes from JBoss community.
Right now we are preferring Hibernate but there are concerns/reasons like EclipseLink developed by Oracle and preferred ORM in Webogic/ Oracle DB world (compatibility of ORM with DB and App. server), support comparison with both ORM, which are preventing to finalize the decision.
Please help me with you views and opinions and share you experience with us so that we can make a perfect decision.
If you want you can also reply to me @ [email protected].
Thanks.The way the ORMs are designed, integration with application servers are relatively simple, and all provides the same features. Also since WebLogic have been around for a while, all ORMs are all well tested in this configuration.
Hibernate has lot more users, and is likely very often used with Oracle DB, so you can expect not much bug against Oracle DB, maybe even less bug than EclipseLink, which is not much used. EclipseLink does provide support for some esoteric Oracle DB features like hierarchical and flashback queries.
OpenJPA and DataNucleus are also JPA compliant. It’s likely that Open JPA has a higher user base than EclipseLink, so less unknown bugs.
Oracle paying support is well known to be a bad joke. It’s a negative return to use this channel, even if they would be free. So in reality, you end up to use the open (free) forum to get support.
What’s was lacking with Hibernate before is Dynamic Fetch Planning, but they now have some support, see http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414. OpenJPA was the first to implement this must have.
EclipseLink has query in memory, which can be used, but the API do not help to leverage it, and EclipseLink’s leadership made it clear that they are not going to make it better, instead they want to push Coherence cache.
Hibernate has an open API for second level cache, which mean you can get out of problem by using another implementation, for example, EHCache seems to be professionally tested, so I would be surprise you find obvious bugs.
I cannot comment on Hibernate source code quality, but I can tell you that locking mechanism in EclipseLink is used to be very fragile, and many concepts are dispersed over the code base.
The runtime monitoring of Hibernate have always been great due to the fact that JBoss have always been strong on JMX, EclipseLink has not much usable features on this.
If I would be you, I would consider OpenJPA or Hibernate instead of EclipseLink, the main reason is that because EclipseLink has a so low user base, I have found lot of obvious bugs in production, like if I was the only user of it. Then, when I submitted bugs to the small development team, which do not encourage user base contribution, they were too busy trying to keep up adding the JPA interfaces on top of their existing proprietary APIs. -
I need some advice regarding Hibernate and JSF. I created a Hibernate Help class and
and I wondering if I should treat this as a manged bean or just as at Util class. If
I should treat this as managed bean should i set the scope to session or application.
<managed-bean>
<managed-bean-name>hiberHelper</managed-bean-name>
<managed-bean-class>foo.bar.HiberHelper</manged-bean-class>
<managed-bean-scope>application or seesion </manged-bean-scope>
</managed-bean->
thanksUse the class as an Util class....I presume you dont need to instantiate the class on user actions..
Purpose of the managed bean is to hold form data or you use it as controllers..that is as user action classes..and yes the managed beans are created on demand.. -
Cannot Hibernate nor Standby anymore
Hello,
T500 Type 2081-CTO
One of our managers came to me and told me that his laptop was acting strange.
It was "hanging" and had to be cold restarted before we could gain access for about 5 more minutes before it froze again.
We replaced the Hard Drive.
We reinstalled XP SP3 onto it and now there is no option to hibernate the notebook. (When choosing "Shutdown" in the options field).
We click "shutdown" and there is no standby nor hibernate choice.
Yes we did go into the video properties under screen-saver -> power options and we found no hibernate button nor tab.
I have updated the BIOS. I have updated the video drivers. I have updated the chipset drivers.
There is no option in the BIOS regarding hibernate.
Any comments welcome.
Thanks,
RickHello there
My problem is quite different, and that´s why I might confuse de topic so apologies in advance.
Well the problem goes like this: a X61 WinXP pro, SP2 doesn´t go to standby or hibernate only on the docking station. Meaning that to make the options work I have to put it in the docking station, restart and the options are available. But after one restart disconnected from the docking station I get standby grayed out.
Tried almost everything, display driver update, chipset update, sonic DLA uninstalled, PM update for the battery, disabling all devices, page file increased, ... I don´t even remember all the stuff tried but nothing.
Any ideas on what might cause this?
My only option is to try SP3 although from my personal experience SP2 is less problematic.
Thanks,

Regarding Spring an hibernate as WebService
Dear All
I need to develop a Webservice with Spring and Hibernate and need to import
as Java Bean Model in NWDS!
Does any body have small application Source code to develop spring and Hibernate as Webservice?
or let me know how to proceed ?
Thanks
ShravanHi Shravan,
first of all I am wondering about the usage scenario. Why do you want to develop with Hibernate and Spring and then convert it to EJB? How about directly starting with EJBs. Developing Web Services based on EJB is pretty straightforward in NWDS. Even simpler if you are using Enterprise Service Builder to generate the wsdls.
If you want to stick with your choice I would recommend you to have a look on the official spring website. There are a lot of tutorials and samples for all components of spring, including web services: [http://static.springsource.org/spring-ws/sites/1.5/reference/html/tutorial.html|http://static.springsource.org/spring-ws/sites/1.5/reference/html/tutorial.html].
Kind Regards,

</service>Hi!
I am using Flash Builder 4.6, BlazeDS, and Hibernate. How to store a webcam snapshot into the MySql Database. I stored Form Items by using RemoteObject into the database. But I failed to store webcam snapshot. I captured that image on Panel component.I converted that image to ByteArray. Now I want to save that image into the database. Please help me in this regard.
thanks in advance.

Transfer Object in JSF, Spring, and Hibernate
The application on which I am working deploys the JavaServer Faces, Spring and Hibernate frameworks.
We are going to use the "transfer object" to move data between J2EE tiers from the front end to the back end and vice versa. In addition, data "types" may need to be converted --
At the front end, the "type" of the data that are entered by users may not match that in the database table. For example, checkboxes may be marked or left blank by users. The "type" of the checkboxes is "boolean" in the JSF backing bean. However, we have either "Y" or "N" for the corresponding field in the database table.
The JSF backing bean holds data as well as controller functionality. Of course, the transfer object holds data only.
With regard to class properties, Is the transfer object an exact copy of the JSF backing bean? And at which tier the data are converted to match their correspoding "types" in the database tables?
We also have the "data objects" which are exact representation of database tables.
Thanks for your advices.Small example: you can decide in the business layer
whether to convert it to boolean or Boolean (which
has a 3rd state: null).But it all goes back to your data model. If your data model supports null for that property, then of course boolean is a poor choice. If that case one could use Boolean. None of this has anything to do with re-usability, which was your objection.
I think the re-usability question goes back to the data model as well. Suppose your data model says this property is boolean valued. However if your database does not support booleans natively, then you need to map the value for storage in the database. But that is the data persistence layers problem.
OTOH, suppose your data model says that this property may be 'Y' or 'N'. Then the Java class represent the business object should not have a boolean property, we should make it match the data model.
However, I think that most cases where people are storing 'Y' or 'N' in a field in the database fall into the first case, where the data model is a boolean and they are working around limitations in the database. There is no reason in that case to perpetuate the same limitations in the Java code. -
How to use composite entities which driven by different PU via hibernate
Hi experts,
There are 2 different persistence unit in my project.
PU_A: Application entities, that can execute all crud operations.
PU_B: This one has some views which contains outside data. I can just read data from here
But i want to create foreign key in some entities which are in PU_A by using immutable-entity which managed by PU_B persistence-unit.
If you could view on following snippets. I have IncomingPaperwork entity which is driven by PU_A and ProjectView which is driven by PU_B.
After i applied this issue; When deploy the application exception that is below occured :

Edited by: webyildirim on Jan 30, 2013 5:36 AMNot quite what I meant - I was suggesting you load the entity immediately after reading it from PU_B, or anytime before associating it into PU_A, so before the merge. What you have not shown though is any code on how you are obtaining IntegrationDepartment and integrating it into PU_A, or what you mean by it is returning a refreshed version of Topic. This problem could also be the result of how your provider works internally - this is a TopLink/EclipseLink forum post so I cannot really tell you why you get the exception other than it would be expected to work as described with EclipseLink as the JPA provider.
So the best suggestions I can come up with are prefetch your entity, try posting in a hibernate forum, or try using EclipseLink/TopLink so someone here might be better able to help you with any problems that arise.

How to integrate hibernate with Stateless Session bean in weblogic10.0
Hi,
I need to invoke hibernate(3.x) DAO from EJB Stateless Session bean(EJB2.x). I am using mysql database. Can somebody please post the configuration.
Thanks in advance,
Rushi.Hi Deepak,
Thanks for your reply.
Actually, our stand alone java application already using spring-hibernate feature. Now we are planning divide our application into modules and deploy each module as ejb beans. As it is already integrated with spring-hibernate we are not using entity beans as of now. My understanding is container uses some default transcation management .so, my question is what are all the configurations needs to be done to let weblogic 10.0 server uses org.springframework.orm.hibernate3.HibernateTransactionManager. I mean, is there are any .xml file in weblogic to configure all these? please reply deepak I am struck here..
Regards,
Rushi. -
Starting Virtual Machine will not start from hibernate mode.
Hi. I had a BSOD and upon rebooting my machine one of my virtual machines is stuck in "hibernate" mode and will not boot up.
I attempted to restore to previous versions of the vmc, but that did not work.
The error i receive is.
"Could not enable integration functions"
Retry or Continue.
Selecting "Continue" states "the operation failed. The virtual machine is not running"
Does anyone have any idea how to get a VPC up and running from this situation?
