Re: Struts 6.1.1. // Ok to migrate to JDK 17, Spring 6, Hibernate 6?

[John]

I believe Spring6 and Hibernate6 are the branches including the JDK17 
javax to jakarta change.

Rather no, yet I'm not sure if Spring 6 and Hibernate do not require 
Jakarta API

Struts2 JQuery plugin failed on Strut2 + Tiles + Hibernate project

[THAN_HVFC]

Hi all!
I am new to Struts2.  I downloaded Strust-2.5.8-all which bundled with Tiles.  
I created my web application with Strust-2.5.8 and Hibernate-5.1.  I deployed 
on Wildfly10 and the app ran fine.  
Now I decide to add JQuery to my project.  So I downloaded 
struts2-jquery-plugin-4.0.2 jar and put it inside my project lib folder and 
deployed on Wildfly10.  I got the error below.   As you can see the JQuery 
plugin breaks the Struts2 web app.  Please help!

i just use the following session approach       in the application.xml          
bean id=cartmgr class=CartManagerImpl scope=prototype                  
property name=cartDao ref=cartDao/          /bean

struts2 json return null if involve hibernate or spring

[john lee]

 is hibernate dao manipulation could affect struts 2 json return?
or spring framework could affect struts2 json return?
my program's struts2 json execution is success if not involve dao or spring 
call.
but if involve hibernate/spring/dao manipulation, then json return is null and 
not returned.

struts integrate with hibernate and spring

[phoenix]

I want to integrate struts2 with hibernate4 and spring4,but i don't know if  i 
need to use spring to manager struts action, is spring manager struts action 
better than struts manage action itself? Which method is better?  I am puzzled 
with how to integrate struts2 with hibernate4 and spring4, Anyone could give me 
whole code which i can learn and run struts2 with hibernate4 and spring4? 
Thanks.

How to implement multi tenancy with separate database in struts and hibernate?

Hi, 

We have an application wherein we want to keep separate database for each 
client. We want to achieve this using multi tenancy approach. A working example

Oracle 12c should fit your needs. Unless you want to recreate this feature

Re: How to implement multi tenancy with separate database in struts and hibernate?

[Néstor Boscán]

If you want to recreate this feature yourself with different databases
you're going to have to map your entrypoint (initial URL) to your specific
client and from there to the specific database datasource. Once you have
the data source, associate it with the SessionFactory and everything will
work correctly from there.

Regards,

Néstor

Re: Hibernate problem with OGNL

[Lukasz Lenart]

2013/3/26 Markus Demetz mar...@demetz.eu:
 Hi,

 I don't know if this is the right place to ask, but maybe there is anyone
 who has experienced the same problem.

 I'm using Struts2 (latest version), with Hibernate (latest version)
 My database models all have getId().

 I have situations, where the getId() method of my model class returns null
 when navigating through OGNL e.g. when
 calling s:property value=#user.gallery.id/.

Have you tried s:property value=user.gallery.id/ or s:property
value=%{user.gallery.id}/

 When I call getId() from the method in my action class (e.g. UserListAction
 iterating though users and calling user.getGallery().getId()), it returns
 the id as expected.
 If I do that first in my action class, then also my s:property.../ renders
 the id as expected; so I thought about a lazy loading issue... all my
 getId() methods are public, NOT final, and the Long id members are
 protected.

 I also tried to add a getMyId() method in the model which calls getId() from
 within the same class.
 getMyId() { return getId(); }

 This surprisingly works and outputs the correct id when calling s:property
 value=#user.gallery.myId/

You know, HHH uses all that magic with proxies, baytecode manipulation
and so ;-)

I've seen this behavior on newly created instances. Hibernate doesn't 
know the ID until the object is persisted to the DB. Hibernate tries to 
delay this as long as possible to minimise DB writes. You would have 
thought a request for the ID would force a DB write but Hibernate 
doesn't seem to implement this behavior. If you want the ID you need to 
force the DB write first.

Hi,

I think I've found the problem.

Now it seems to work!

Thank you, and sorry for misplacing my question here!

Store Interceptor not working with field error (using Hibernate validation)

[cyanoboy]

I have a Jsp with some textfields, these are validate using Hibernate
validation annotation (@Valid or @NotNull in the action) except one (input
image file) that is validate with default Struts2 validation (using
ActionName-validation.xml). I want to redirect to another action when the
submitted form is invalid (when textfields are null), and I want to store
fields error.

I tried with this:

interceptors
interceptor name=SessionCheckInterceptor
class=util.SessionCheckInterceptor/
interceptor-stack name=mySessionValidationStack  
interceptor-ref name=defaultStackHibernate /
interceptor-ref name=SessionCheckInterceptor /
/interceptor-stack  
/interceptors 

default-interceptor-ref name=mySessionValidationStack/ 

action name=insert class=actions.InsertAction
interceptor-ref name=mySessionValidationStack
image/png
/interceptor-ref 
interceptor-ref name=store
STORE
/interceptor-ref
interceptor-ref name=defaultStack /
result name=success type=tiles baseLayout/result
result name=error type=redirectAction 
showinsertform
/result
result name=input type=redirectAction 
showinsertform
/result
/action

action name=showinsertform class=actions.ShowInsertFormAction  
interceptor-ref name=mySessionValidationStack /
interceptor-ref name=store
RETRIEVE
/interceptor-ref
result name=success type=tiles insert/result
result name=error type=tiles baseLayout/result
/action 

But when I sumbit the form, the redirect succeed without showing me fields
error messages. Maybe I'm setting wrong the interceptor? Using hibernate I
need to override something? If I try to set manually error messages in the
action (with addActionError), they works! Can it be that hibernate error
fields messages are not stored in the session?

[pirzada rashid]

Hi,

I am using struts2-fullhibernatecore-plugin-2.2.2-GA in a demo strut2

using all the latest jars.

Problem is in the above code when Session and Transaction is injected. I am
wondering that this might be problem of
struts2-fullhibernatecore-plugin-2.2.2-GA not supporting

hibernate-validator-4.3.0.Final

because plugin site
http://code.google.com/p/full-hibernate-plugin-for-struts2/ mentioned that
only supported versions are

*This plugin is compatible with Hibernate Validator 3.1.0 and 4.0.2 (since
2.2 version)*.

*Is that the problem. Have anyone used this plugin with above mentioned

You must initializate session attribute.

 Hi,

 I am using struts2-fullhibernatecore-plugin-2.2.2-GA in a demo strut2
 project with Hibernate. I tried my best but can not make it work. I am
 using all the latest jars.

 *Am I missing something?*

 Please help

 Problem is in the above code when Session and Transaction is injected. I am
 wondering that this might be problem of
 struts2-fullhibernatecore-plugin-2.2.2-GA not supporting

 hibernate-release-4.1.6.Final
 hibernate-validator-4.3.0.Final

 because plugin site
 http://code.google.com/p/full-hibernate-plugin-for-struts2/ mentioned that
 only supported versions are

 *This plugin is compatible with Hibernate Validator 3.1.0 and 4.0.2 (since
 2.2 version)*.

 *Is that the problem. Have anyone used this plugin with above mentioned
 versions?*

 *One more question: Can we use this plugin in the production environment?*

Thanks. How initialize session where it should auto inject? . Please give
me example.

DAOImpl for hibernate got few general and specific questions

[pirzada rashid]

Hi,

I have CustomerDAOImpl where I am doing CRUD. Few questions.

*Q1 -* Should I declare Session at class level or each method level OR
declare at class level and initialize at each method level?

*Q2 -* When fetching data like in listCustomer, Should I
session.beginTransaction(); and than commit it? . I think on fetch,
transaction shouldn't apply but if I am not atleast
session.beginTransaction(); gives error saying need active transaction.

*Q3 -* I have read that session is expensive and should not close it till
application is running. Where should I close and open it if not using
Spring etc?

*Q4 -* I get *WARNING* Note:
C:\Struts2_HelloWorld\src\com\myapp\dao\CustomerDAOImpl.java uses unchecked
or unsafe operations. Why is that and how to fix this?

*if you answer most of my problems will be clear. Thanks*

*CustomerDAOImpl.java*

package com.myapp.dao;

import com.myapp.model.Customer;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;

import java.util.List;

public class CustomerDAOImpl implements CustomerDAO {

Session session = HibernateUtil.getFactory().getCurrentSession();
Transaction tx = null;

//add the customer
public void addCustomer(Customer customer) {
tx = session.beginTransaction();
try {
session.save(customer);
tx.commit();
} catch (HibernateException e) {
if (tx != null) tx.rollback();
e.printStackTrace();
}
}

//return all the customers in list
public ListCustomer listCustomer() {
tx = session.beginTransaction();
return session.createQuery(from Customer).list();
}
}

*HibernateUtil.java*

package com.myapp.dao;

import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil {

private static SessionFactory factory = getSessionFactory();
private static ServiceRegistry serviceRegistry;

private static synchronized SessionFactory getSessionFactory()
throws HibernateException {
Configuration configuration = new Configuration().configure();
serviceRegistry = new
ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
return configuration.buildSessionFactory(serviceRegistry);
}

Not sure; can't really read your post. It looks like there's a parsing

Re: cant list data with hibernate struts

[Dave Newton]

Do all those classes in your config exist? Are they really all in the
default package?

Re: Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

You might take a look at [1], particoularly the section called root
object.
That's because I'm afraid that json plugin is trying to serialize your EJB
service.

Re: Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

[Ken McWilliams]

Solved! I've seen a number of posts relating to this issue but none with
solutions...

In searching for how $JAVASSIST_READ_WRITE_HANDLER came into existence
we find:
http://www.docjar.com/html/api/org/hibernate/tool/instrument/javassist/FieldTransformer.java.html


There we can see the getter for $JAVASSIST_READ_WRITE_HANDLER is
actually getFieldHandler so the exclude parameter becomes:

@Action(value = list-clients, results = {
@Result(type = json, params = {
excludeProperties,
^list\\[.*\\]\\.fieldHandler\\..*
})
})

And it all works... 

Just tested the shorter .*\\.fieldHandler\\..* and it works too, which
is much better because now there is one solution for all such
instrumented entities!

Re: Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

[Ken McWilliams]

I need the root object to be list so this isn't going to help.

I'm pretty sure it is not trying to serialize the EJB service, the json
plugin will only try to serialize properties which have getters. 

According the debugger there seems to be a public property directly in
the entity called $JAVASSIST_READ_WRITE_HANDLER, I'm quite confident
that is in the attempt to serialize this object the issue occurs.

To be extra sure I set list as the root and the issue still occurs.

RE: How to implement EJB 3.0, JPA, Hibernate and Struts 2 in one application?

[Marcus Bond]

Have never tried this out with ejb since it isn't isn't my thing but just
the same as a spring / struts (or any other framework) app your service
layer would be called from your struts actions such that struts isn't likely
to know about or care about the fact that the service  classes are ejb,
spring beans or anything.

Sooo.. each technology you mention has different purposes in your app and
should work together fine, Struts will provide your controllers and  the
actions will reference an ejb service layer with some ejbs using JPA via an
injected entity manager for which the underlying implementation for JPA
would be hibernate.. job done.

In answer to your second question, afaik Seam may be worth a look if you're
after ejb webapps..

struts2 hibernate

[Saeed Najahi]

hello guys, plz i need some help concerning struts 2.2.3 and hibernate
3.6.3,
the problem i'm having is that the jars seem to keep fighting with each
other :( exceptions that stop me from even daring to write a single line of
code that implicates hibernate and struts, the documentation doesn't help
much unfortunatly, explanation or indication of what version of what jar is
needed isn't mentioned, i've never even thought that javassist was needed
untill i downloaded a struts project from google code, there was no
mentioning of it whatsoever in the tutorial
would anyone kindly give me a pom.xml of a working struts2 and hibernate
project (in addition to the full hibernate plugin), please help me out i'm
pretty much depressed right now,

RE: RE: Re : Re : ModelDriven Hibernate Entities

[CRANFORD, CHRIS]

Burton -

I continued to dig around the code yesterday despite my frustration with the 
situation in not being able to find a way to make all this work.  It just 
didn't seem right that this wouldn't work IMO.  After turning on Spring's DEBUG 
and watching the transaction management statements happen, I stumbled across 
what I feel was the culprit.

We have a number of interceptors in our code base that perform various 
initialization activities before the destination action is ever invoked along 
with some which do pre-result and post-result activities.  After looking at my 
interceptor stack, one of them was doing a merge action to write some 
breadcrumb data to an audit table during a pre-result listener.  

So the series of events were:

1. Model Driven action called
2. Model loaded from database (attached entity)
3. Parameters were loaded into model (entity now modified)
4. Validation occurred
5. Execute method fired (simply returns SUCCESS)

Well after the action returns SUCCESS and the PreResultListener gets executed 
that does the EntityManager MERGE call.  This not only persisted the audit 
record to the database but it also commits any changes pending, which would 
include the modified entity in #3 above.

From what I have gathered with OSIV, the transaction is opened and you can 
query the database and make changes to your entities but once a call is made 
to the entity manager to remove/persist/merge an entity, all bets are off; any 
pending changes will be flushed.

So what I decided to test was adding one more interceptor to the stack that 
clears the entity manager after the action's execution; effectively forcing a 
rollback for any entities which were not explicitly persisted.  Then the audit 
interceptor was changed from a pre-result to a post-result action and takes 
place right after the clearing of my entity manager.  Now the audit service 
doesn't persist any pending changes from my action environment.

Anyone see any flaws or issues with this?  So long as my action is making a 
single call in my execute() method to my business logic with my model, then I 
should be ok?

I think your fix sounds logical.

My true knowledge of the @Transactional annotation isn't that great
although I use it quite a bit (yikes), so this suggestion may be way
off base but would setting the code inside your pre-result or
post-result inteceptor as @Transactional(propagation =
Propagation.REQUIRES_NEW) help in any way?

 From: chris.cranf...@setech.com
 To: user@struts.apache.org
 
 I had started down a path of using the ModelDriven interface from Struts
 because I find it really helps maintain a class action class without
 large numbers of get/set methods for screens that contain a lot of form
 fields.  
 
 However, I am finding at least with how I have attempted to approach
 ModelDriven to have several drawbacks.  For example, by using the OSIV
 (Open Session In View) filter, I am finding that when Struts sets the
 properties on the entity and afterward if an exception is thrown, caught
 and handled and doesn't trigger Hibernate to actually rollback; the
 changes are persisted which leaves my entity in a dirty inconsistent
 state.
 
 How have others solved this by using your entity domain POJOs in your
 view?  
 
 Do you use them detached from the session so that you explicitly have to
 merge them to the session to be persisted?  If so, how do you deal with
 multiple lazy loaded collections in your entity?  
 
 Or would using DTO objects from my service layer a better alternative to
 insure that no data is actually persisted to the database that shouldn't
 be?

This is what has me confused.  I don't believe that Hibernate's FLUSHMODE is 
even being set and I am starting to question if that is because of how I am 
using JPA in conjunction with Hibernate with Spring's transaction management 
system.

  property name=persistenceXmlLocation

I question if this is because I am using the JpaTransactionManager?  
I checked Hibernate's FlushMode and it's being set to AUTO.

I don't use Spring to instantiate my actions, they're not defined like that.

Spring injects my services into my actions because I use the @Autowired 
annotation.  I then have all my services and DAO classes annotated with the 
@Service and @Repository annotations so that I can wire then through injection. 
 But each action instance itself is instantiated by Struts itself and not 
Spring.  The only other things that I have spring managing is the transactions 
and security.

 It's exactly what I meant (you can leave in your service class too).
 The object factory must be spring and your class name inside the
 action configuration must contain the bean id (instead of the real
 class name).
 I'm not sure if it works but it worth a try though.

  login
   page.
   
But prior to logging back in; I checked the database and
 noticed
  that
   the record was in fact persisted with the changes from the form.
  All I
   can gather is the following:
   
1. Request comes in for Struts
2. Hibernate Session opened via OSIV
3. Model is loaded from DB via prepare()
4. Struts copies parameters into the model
5. Validation/Interceptors fire
6. Authentication Interceptor detects timed out session,
 returns
   LOGIN
7. User presented with login page
8. OSIV filter closes, changes from #4 persisted.
   
I then created a simple test action where I load a persist
 entity
   from the DB in a ModelDriven action, I call the action passing
   parameters that are properties on the entity.  Then the execute()
   method does nothing more than return SUCCESS which maps to my
   /pages/done.jsp.  The changes are committed.
   
I'd prefer that changes aren't committed unless I explicitly
 call
  to
   do so on the EntityManager; however I understand Hibernate/JPA's
   reasons behind why it works the way it does.

 It's exactly what I meant (you can leave in your service class too).
 The object factory must be spring and your class name inside the
 action configuration must contain the bean id (instead of the real
 class name).
 I'm not sure if it works but it worth a try though.

I can only conclude that either something is severely lost in my
understanding of a Struts2 ModelDriven action coupled with Spring3 and
Hibernate/JPA.  I have tried numerous configuration changes,
annotations, etc and nothing has appeared to avoid allowing dirty data
to make it to the database and I just cannot continue with this risk; it
just jeopardizes integrity.

So unless someone can shed some light on my implementation, showing what
could be flawed; then I need to go down a different path.  

I like the notion that the ModelDriven does a lot of the grunt work for
me with respect of populating my entity based on form properties and
keeps my action class very clean and free of form bloat; however I feel
it puts some risks on the table which I could easily avoid by not
allowing the framework to modify my persistent entity and force me to
manage the copy/update of the entity accordingly when applicable.

Re: RE: Re : Re : ModelDriven Hibernate Entities

[Burton Rhodes]

I have never run into this issue while using OiSV, but couldn't it be
easily solved by not referencing any related entity or collections
directly from the model you are modifying in your action?  In other
words, the object that is in your model (e.g Customer) would be in
getModel() and in the form for the JSP, but all other data dispayed on
the page would be reference by a clean version of Customer.  I'm
sure it can't be that simple, but trying to help.

ModelDriven Hibernate Entities

[CRANFORD, CHRIS]

I had started down a path of using the ModelDriven interface from Struts
because I find it really helps maintain a class action class without
large numbers of get/set methods for screens that contain a lot of form
fields.  

However, I am finding at least with how I have attempted to approach
ModelDriven to have several drawbacks.  For example, by using the OSIV
(Open Session In View) filter, I am finding that when Struts sets the
properties on the entity and afterward if an exception is thrown, caught
and handled and doesn't trigger Hibernate to actually rollback; the
changes are persisted which leaves my entity in a dirty inconsistent
state.

How have others solved this by using your entity domain POJOs in your
view?  

Do you use them detached from the session so that you explicitly have to
merge them to the session to be persisted?  If so, how do you deal with
multiple lazy loaded collections in your entity?  

Or would using DTO objects from my service layer a better alternative to
insure that no data is actually persisted to the database that shouldn't
be?

 I had started down a path of using the ModelDriven interface from
 Struts
 because I find it really helps maintain a class action class without
 large numbers of get/set methods for screens that contain a lot of form
 fields.
 
 However, I am finding at least with how I have attempted to approach
 ModelDriven to have several drawbacks.  For example, by using the OSIV
 (Open Session In View) filter, I am finding that when Struts sets the
 properties on the entity and afterward if an exception is thrown,
 caught
 and handled and doesn't trigger Hibernate to actually rollback; the
 changes are persisted which leaves my entity in a dirty inconsistent
 state.
 
 How have others solved this by using your entity domain POJOs in your
 view?
 
 Do you use them detached from the session so that you explicitly have
 to
 merge them to the session to be persisted?  If so, how do you deal with
 multiple lazy loaded collections in your entity?
 
 Or would using DTO objects from my service layer a better alternative
 to
 insure that no data is actually persisted to the database that
 shouldn't
 be?

I use the standard paramsPrepareParamsStack interceptor from Struts.

All I have done on my end is wrap this interceptor stack with a few application 
specific interceptors that control things such as authentication required, 
auditing, and logging.  I stepped upon my issue one day when I had returned 
from lunch and my session had timed out.  I hit the SAVE button on a form and 
it redirected me to our login page.  

But prior to logging back in; I checked the database and noticed that the 
record was in fact persisted with the changes from the form.  All I can gather 
is the following:

1. Request comes in for Struts
2. Hibernate Session opened via OSIV
3. Model is loaded from DB via prepare()
4. Struts copies parameters into the model 
5. Validation/Interceptors fire
6. Authentication Interceptor detects timed out session, returns LOGIN
7. User presented with login page
8. OSIV filter closes, changes from #4 persisted.

I then created a simple test action where I load a persist entity from the DB 
in a ModelDriven action, I call the action passing parameters that are 
properties on the entity.  Then the execute() method does nothing more than 
return SUCCESS which maps to my /pages/done.jsp.  The changes are committed.

I'd prefer that changes aren't committed unless I explicitly call to do so on 
the EntityManager; however I understand Hibernate/JPA's reasons behind why it 
works the way it does.

 Hi Chris,
 first,
 you might have another pb, because struts2 does not change your model
 if a
 validation failed. In may case, the model is not changed so not
 persisted. Do u
 use validation and workflow interceptor ?
 second,
 you are right about MVC pattern, but, just be aware that when you use
 OSIV
 pattern, hibernate call backend service when loading data...:-)) so
 your JSP is
 not just a view in that case
 
 
 I wrote my first mail thinking you wanna rollback after an exception
 occured.

 While that may work for you, I wouldn't place anything Hibernate or
 persistence
 related in my JSP pages at all.  In my mind, this breaks the entire
 reasoning
 behind MVC and the view simply there to render data.  If the view is
 doing
 anything beyond that, I have a design problem, but again that's my
 opinion.
 
 But what about when you use the INPUT result code in your execute()
 method.
 
 If I return the user to the INPUT method because maybe I'm not using
 the Struts
 validation framework and doing it myself in my execute() method or I
 have some
 complex conditions I must check for before I save the data.  In this
 case, by
 returning INPUT and setting some action field or error messages to be

 isn't
 fired either; leaving your entity persisted with likely dirty data.

It might just be an order of interceptors problem.  One of your first
interceptors should be your login check.  That should definitely happen
before the standard paramsPrepareParamsStack is run.

Yes, that was the issue, it was interceptor order related.

Now if only I could get the persistent entity not to be flushed under specific 
conditions:

 - Exception 
 - Non-SUCCESS return code, etc.

 osiv filter (should) set flushing to never (now manual) to prevent accidental 
writes on the session so

MapString, String properties = new HashMapString, String();
properties.put( org.hibernate.flushMode, manual );
javax.persistence.EntityManager em = createEntityManager( properties );
em.getTransaction().begin();

/* * always reopen a new EM and clse the existing one*/
protected EntityManager createEntityManager(Map properties) {
if ( em != null  em.isOpen() ) {
em.close();
}
em = factory.createEntityManager( properties );
return em;
}

Re: RE: Re : Re : ModelDriven Hibernate Entities

[Maurizio Cucchiara]

It's exactly what I meant (you can leave in your service class too).
The object factory must be spring and your class name inside the
action configuration must contain the bean id (instead of the real
class name).
I'm not sure if it works but it worth a try though.

Re: generate SQL Hibernate Query using session

[Mead Lai]

I think you may use the Composite Class in Hibernate.
Query q = session.createQuery
( select new NewCompositeClass(members, classInfo.className)  +
 from Members members, ClassInfo classInfo  +
 where members.level = classInfo.classCode );
and you need a class:NewCompositeClass.java

Mead

RE: generate SQL Hibernate Query using session

[CRANFORD, CHRIS]

Jerson -

What I would likely suggest you consider is creating a DTO object that
resembles your result from the SQLQuery.  You can then use one of the
stock Hibernate Transformers to convert the SQL results into instances
of this DTO Bean and then you can return the beans to your view to
iterate over.

Here's a simple example:

public List getQueryUsingResultTransformer() {
  SQLQuery query = session.createSQLQuery(SELECT SOME FANCY DATA);
  /* do other stuff */
  query.setResultTransformer(new
AliasToBeanResultTransformer(YourDTO.class));
  return(query.list());
}

Another alternative would be to iterate the result set yourself 

public ListYourDTO getQueryDoingSelfInstantiation() {
  ListYourDTO myList = new ArrayListYourDTO();
  SQLQuery query = session.createSQLQuery(SELECT SOME FANCY DATA);
  /* do other stuff */
  List results = query.list();
  Iterator i = results.iterator();
  while(i.hasNext())
  {
Object[] row = (Object[]) i.next();
/* each row has a 0-based index for each column of query */
YourDTO dto = new YourDTO();
/* set values on dto */
myList.add(dto);
  }

Both basically do the same; however I find that using the AliasToBean

 Hi,
   I am trying to generate SQL query using session.createSQLQuery and

Jerson -

What I would likely suggest you consider is creating a DTO object that
resembles your result from the SQLQuery.  You can then use one of the
stock Hibernate Transformers to convert the SQL results into instances
of this DTO Bean and then you can return the beans to your view to
iterate over.

Here's a simple example:

public List getQueryUsingResultTransformer() {
  SQLQuery query = session.createSQLQuery(SELECT SOME FANCY DATA);
  /* do other stuff */
  query.setResultTransformer(new
AliasToBeanResultTransformer(YourDTO.class));
  return(query.list());
}

Another alternative would be to iterate the result set yourself 

public ListYourDTO getQueryDoingSelfInstantiation() {
  ListYourDTO myList = new ArrayListYourDTO();
  SQLQuery query = session.createSQLQuery(SELECT SOME FANCY DATA);
  /* do other stuff */
  List results = query.list();
  Iterator i = results.iterator();
  while(i.hasNext())
  {
Object[] row = (Object[]) i.next();
/* each row has a 0-based index for each column of query */
YourDTO dto = new YourDTO();
/* set values on dto */
myList.add(dto);
  }
  return(myList);
}

Both basically do the same; however I find that using the AliasToBean
transformer is much cleaner code :)

 I'm pretty sure that your action class contains a reference to a

 If I'm right you could simply change your root parameter via action

RE: JSON Error - Hibernate Entities

[CRANFORD, CHRIS]

I eventually decided to write a DTO wrapper that took my POJO as a constructor 
argument and extracted the fields I wanted to pass instead of trying to 
serialize the entire object and that seemed to work.  It just appears that the 
amount of information within the POJO was creating issues for JSON to serialize 
it; however I cannot isolate exactly what is the problem in the POJO.  All of 
the properties in the POJO are serializable :=/.

My guess is that the json plugin was navigating the entire graph object,
trying to serialize the entire java world.

 when i run the same code via struts i get the following exception,
 the code is:

 public static void main(String[] args) {
        ProductsDAO pd = new ProductsDAO();
        ListProducts l = pd.findByPUrlcomponent(ABC);
        Products pr = l.get(0);
        System.out.println(pr.getPId().toString());
    }
 Pl. advice i am using myeclipse,

 the exception is

Re: error while running code of struts2.x and hibernate 3.3: java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I

[Maurizio Cucchiara]

It looks like there something wrong in your dependencies. Check your
classpath (I'm not sure, but at first glance it'd seem the antlr library
version).
I could be proprably wrong but it not seems a struts problem.

[abhishek jain]

hi,
I am using myeclipse , and using its own default classpath.
I have two antlr-2.7.2.jar in Struts core libraries and antlr-2.7.6.jar in
hibernate core libraries.

I tried removing antlr-2.7.2.jar  and still the problem persists.

thanks

Re: error while running code of struts2.x and hibernate 3.3: java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I

[Dave Newton]

You need to determine which versions you're actually depending on.

Are you attempting to do dependency management manually?!

How are you doing dependency management?

I'm not sure; I haven't used MyEclipse in some time (but I did for
quite awhile; very often worth the (minimal) cost.

I would strongly pursue the library conflict idea people have
mentioned--perhaps you could ask for support from MyEclipse in
determining how to configure it to avoid the conflict, or at least
they could point you in the right direction if it's not an issue
directly related to MyEclipse.

Do you know if you're working with a Maven-based project or not?

Decent tutorial or working example of Hibernate 3 + Struts 2 + Tiles 2 on myeclipse

[abhishek jain]

Hi,
Can anyone forward me to a good  tutorial or a working example of Hibernate
3 + Struts 2 + Tiles 2 on myeclipse. Maybe a project i can import in
myeclipse or so,
any simple skeleton will do,

I tried my hand directly but cannt get through i get some exceptions
everytime i add struts and hibernate with tiles capabilities in myeclipse. I
think some libraries default in Myeclipse are conflicting each other .

thanks

[adam pinder]

make sure you only add additional jars into the web app itself and avoid 
(mostly) adding jars into common library folders.
i use struts2 and hibernate3 but not tiles and have no problems like yours.
