[Hibernate] Uncommitted transaction using Hibernate + Bitronix

[Murthy G. <mur...@ho...>]

Hi All: I am having problems with committing transactions using Hibernate + Bitronix where the call to persist occurs in another jar. For example, if I have jarA and jarB. JarA begins a transaction and calls a method in jarB. The method in jarB persists its data. Finally jarA commits the transaction. However, the commit doesn't go through as Bitronix throws an exception saying there is no transaction.

Some relevant code:

Jar A:
void doStuffInJarA() {
    BitronixTransactionManager btm = TransactionManagerServices.getTransactionManager();
    btm.begin();
    callMethodInJarB();
    btm.commit();
}
...
Jar B:
void callMethodInJarB() {
    MyDAO mydao = new MyDAO();
    mydao.persist(myObject);
}

[Hibernate] Exception message throwing in Query.iterate() in HQL is partially wrong .

[Ganesh K. C. <gan...@gm...>]

Hi ,

When i am trying to execute iterate method on Query Object (Query Object is
created from HQL) the exception massage "fetch may not be used with scroll()
or iterate()" is throwing out. This massage is misleading the developer
because it is correct that we can't use Join condition with iterate but we
can use it with scroll . So i think this is a small bug which has not any
impact on the execution of the program but it is creating wrong conception
among developers.

Thanks,
Ganesh

There is no piont.  However, it's not part of any public API.  There are probably more practical bugs to fix.

Why do you need to serialized the parse trees?  It would be better to re-parse the string in order to get all the other non serializable references anyhow.

Otherwise it is not worth to implement serializable interface by DotNode class because ultimately we are not able to serialize it in the current form .

Is it a bug or something else ??

[Hibernate] Typo in manual hibernate entitymanager

[Geoffrey De S. <ge0...@gm...>]

In the hibernate entitymanager manual, section 6.1. Bulk update/delete:


String ejbqlUpdate = "update Customer set name = :newName where name = 
:oldName"
int updatedEntities = entityManager.createQuery( hqlUpdate )


The variable name changes: from ejbqlUpdate to hqlUpdate. It should be 
the same.

2) Do you agree that hibernate needs improvement to support this kind of

I am able to fetch the mapping using workarounds (filters & a change in
hibernate source code to enable filter for one-to-one).
The problem is with save operation..

active? Moreover i saw JBOSS JIRA for hibernate (
https://jira.jboss.org/jira/secure/IssueNavigator.jspa)..
Are these different or same ?

2) I changed the hibernate source code. Hence one-to-one with filters are
working fine in my case.. How can i contribute my changes to hibernate ?

[Hibernate] Hibernate Newbie Question

[Francisco R. E. <fri...@4m...>]

Hello everyone!,

I have a newbie question about hibernate, later of try and try to understand
I cannot and then I m here, my question is the following:

I have 3 Classes: Form.java  / Question.java  / Option.java
in which I formulate the relationship like a survey: Form has many
Questions  / Questions has many Options  ....and in code I have:

Form.java:
   @OneToMany(mappedBy="form",cascade = CascadeType.ALL, fetch =
FetchType.LAZY)
     private List<Question> questions = new ArrayList<Question>();

Question.java
  @ManyToOne (cascade = {CascadeType.PERSIST, CascadeType.MERGE})
    public Form getForm() {
        return form;
    }
    @OneToMany(mappedBy="question",cascade = CascadeType.ALL, fetch =
FetchType.EAGER)
    public List<OptionValue> getOptionValues() {
        return optionValues;
    }

Option.java
 @ManyToOne
    public Question getQuestion() {
        return question;
    }

Later when I try to Create a Form form another form already created... I
have the following error:
Object references an unsaved *transient instance* - *save the transient
instance before flushing*: x.yyy.Question
I don't understand very well the concept of cascade and how this works ...it
seems that I want to save one option value before Question ?

Its is the code for create other form from another:

List questionsToAdd = formManager.getQuestionsById(new Long(idNewForm));

  form.setQuestions(questionsToAdd);

       //formManager.saveForm(form);


        for(int i=0; i<questionsToAdd.size();i++){
            Question questionOld = (Question) questionsToAdd.get(i);

            Question questionNew = new Question();
            questionNew.setLabel(questionOld.getLabel());
            questionNew.setTypeQuestion(questionOld.getTypeQuestion());
            questionNew.setPosition(questionOld.getPosition());

questionNew.setHasOptionsToAdd(questionOld.getHasOptionsToAdd());
            questionNew.setQuestionText(questionOld.getQuestionText());

             questionNew.setForm(form);
             questionManager.saveQuestion(questionNew);



            List optionsToAdd = questionOld.getOptionValues();

                         for(int j=0; j<optionsToAdd.size();j++){
                             OptionValue optionValueOld = (OptionValue)
optionsToAdd.get(j);
                             OptionValue optionValueNew = new OptionValue();

optionValueNew.setValueOption(optionValueOld.getValueOption());

optionValueNew.setValue_column(optionValueOld.getValue_column());

optionValueNew.setValue_row(optionValueOld.getValue_row());

optionValueNew.setIsOptionColumn(optionValueOld.isIsOptionColumn());

optionValueNew.setIsOptionRow(optionValueOld.isIsOptionRow());

optionValueNew.setLabel(optionValueOld.getLabel());

optionValueNew.setImage(optionValueOld.getImage());

optionValueNew.setIsFieldOther(optionValueOld.isIsFieldOther());

optionValueNew.setValueFieldOther(optionValueOld.getValueFieldOther());

optionValueNew.setIsActive(optionValueOld.getIsActive());

optionValueNew.setType(optionValueOld.getType());

[Hibernate] Logical Delete with cascade

[Emanuel G. <est...@gm...>]

Hi all, my name is Emanuel, i'm from Brazil and working with a large project
using Hibernate, a great software.

in it easy.
Any help will be appreciated, i need it quick for the project.

Many thanks

[Hibernate] Select with oldest index of join

[Mitchell, S. <Ste...@um...>]

Assume you have two tables: Order and ChangeHistory.  Order has a
one-to-many relationship with ChangeHistory mapped to
order.changeHistory.  Order history has an update date.  How can I do a
select an Order based on a specific Date that the FIRST update occurred?
In pseudo code this is what I am trying to do:

order.getChangeHistory().get(0).getUpdateDate() = aDate

-- OR --

order.getChangeHistory().get(0).getUpdateDate()  between startDate and
endDate

Below would return any change history for a given date, not just the
first change.  

final Criteria criteria = getSession().createCriteria( Order.class );
if ( searchCriteria.getUpdateDate() != null ) 
{  
     criteria.createCriteria( "changeHistory" ).add( Restrictions.eq(
"updateDate", searchCriteria.getUpdateDate() ) );
}

How do I only get the OLDEST change for an order that happened on a
given date?

[Hibernate] what isAssociationFetch() method does ??

[Ganesh K. C. <gan...@gm...>]

Hi,

There is a method isAssociationFetch() in org.hibernate.event.LoadEvent
class which returns boolean value .

actually i have a situation in which i have "Person" class and this class
has a reference of "Address" class . when the person class is loading the
isAssociationFetch() method returns true . but it is the outermost class .

so, could anybody tell me please what this method does actually and what is
meaning of its return value ??? why is returns true for Person class ??

Thanks,
Ganesh
