Im having great difficult binding the value of a checkbox to an object thats nested inside a List during a post back. Is there an issue with webflow and nested objects inside a list?.
jsp
<div style="margin-left: 15px; margin-bottom: 8px;">
<form:checkbox id="firmUserBeingEditedPermissionList[${status.index}].cascading" path="firmUserBeingEditedPermissionList[${status.index}].cascading"
onclick="toggleCascading(${status.index}, this, event);"/><spring:message code="setFirmPermissions.cascading" />
</div>
flow.xml
<input name="userName" required="true"/>
<on-start>
<evaluate expression="firmUserPermissionDetailViewBuilder.createFirmUserPermissionDetailView(userName)" result="flowScope.firmUserPermissionView" />

thank you #mechkov for your time and help,
My problem is resolved by changing my configuration file, so I have used a Configuration Class with annotations and its works so fine, I still Don't know where the problem was
#Configuration
#ComponentScan(basePackages = "your package")
#EnableTransactionManagement
public class DatabaseConfig {
protected static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "password";
protected static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://localhost:3306/databasename";
protected static final String PROPERTY_NAME_DATABASE_USERNAME = "login";
private static final String PROPERTY_PACKAGES_TO_SCAN = "where your models are";
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter){
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource);
entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);
return entityManagerFactoryBean;
}
#Bean
public BasicDataSource dataSource(){
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);
ds.setUrl(PROPERTY_NAME_DATABASE_URL);
ds.setUsername(PROPERTY_NAME_DATABASE_USERNAME);
ds.setPassword(PROPERTY_NAME_DATABASE_PASSWORD);
ds.setInitialSize(5);
return ds;
}
#Bean
public JpaVendorAdapter jpaVendorAdapter(){
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabase(Database.MYSQL);
adapter.setShowSql(true);
adapter.setGenerateDdl(true);
//I'm using MySQL5InnoDBDialect to make my tables support foreign keys
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect");
return adapter;
}
#Bean

return new JpaTransactionManager(entityManagerFactory);
}
}
I do not know if anyone who is reading this (today) has the same case as mine, but I had the same problem. Luckly, I could fix it by simply putting the following in my spring-conf.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
...
xmlns:tx="http://www.springframework.org/schema/tx"
...
xsi:schemaLocation="
...
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<bean id="tManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emf" />
</bean>
<!-- This does the trick! -->
<tx:annotation-driven transaction-manager="tManager" />
Note: I'm using declarative transactions through annotations. So, if you do, annotating your method with #Transactional can also solve your problem.
REFERENCE:
http://blog.jhades.org/how-does-spring-transactional-really-work/
http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/transaction.html
Just to confirm, that adding last bean definition solves this issue !
My config class is as below :
#Configuration
#EnableTransactionManagement
#ComponentScan
public class OFSConfig {
#Bean
public IDAO<FuelStation> getFSService() {
return new FSService();
}
#Bean
public LocalEntityManagerFactoryBean emfBean() {
LocalEntityManagerFactoryBean e = new LocalEntityManagerFactoryBean();
e.setPersistenceUnitName("org.superbapps.db_OWSDB_PU");
return e;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory em) {
return new JpaTransactionManager(em);
}
}
The service itself is as follows :
#Transactional
#Repository
public class FSService implements IDAO<FuelStation> {
#PersistenceContext
private EntityManager EM;
public EntityManager getEM() {
return EM;
}
public void setEM(EntityManager EM) {
this.EM = EM;
}
#Override
public List<FuelStation> getAll() {
return EM.createNamedQuery("FuelStation.findAll")
.getResultList();
}
#Override
public FuelStation getByID(String ID) {
FuelStation fs = (FuelStation) EM.createNamedQuery("FuelStation.findById")
.setParameter("id", ID)
.getSingleResult();
return fs;
}
#Override
public void update(FuelStation entity) {
EM.merge(entity);
}
}
In earlier version of Hibernate , saveorUpdate fires insert or update query based on the entity.
But in hibernate 4.3.7 fires update query after every insert.I see both insert and update query.

Log4j Logs:-So when i run createOrUpdate method of MessageLoggerDAOImpl for inserting MessageLogger entity first time , i see below two query
[05 Mar 2015 12:11:15:365] DEBUG SQL::logStatement:109 - insert into LOGGER (LAST_UPDATED_TIMESTAMP, VERSION, ACTION, CP, REQUEST, RESPONSE, SEND_FROM, SEND_TO) values (?, ?, ?, ?, ?, ?, ?, ?)

Its not the bug.Its my mistake.I have also the event listener on saveorUpdate and i am also saving the object in it.
#Component
public class SaveOrUpdateDateListener extends DefaultSaveOrUpdateEventListener {
/**
*
*/
private static final long serialVersionUID = 1L;
#Override
public void onSaveOrUpdate(SaveOrUpdateEvent event) {
if (event.getObject() instanceof LastModifiable) {
LastModifiable record = (LastModifiable) event.getObject();
record.setLastUpdatedTimestamp(new Date());
}
//super.onSaveOrUpdate(event); // remove this line solve my problem
}
}
Sorry for inconvenience
Hi i am trying to integrate jpa with spring mvc and getting "no transaction is in progress" when trying to call flush() method.
I can make out that something is wrong with transactions even though i have used #Transactional the method is not running in a transaction.

You may try creating a persistence.xml file .
You can take a look at te following example : JTASessionContext being used with JDBCTransactionFactory; auto-flush will not operate correctly with getCurrentSession()

Generic DAO:
public interface DAO<T> {
T save(T t);
void delete(T t);
}
#Transactional
public abstract class DAOImpl<T> implements DAO<T> {
#Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public Session getSession() {
return sessionFactory.getCurrentSession();
}
#Override
public T save(T t) {
getSession().persist(t);
return t;
}
#Override
public void delete(T t) {
getSession().delete(t);
}
}
AccountDAO:
public class AccountDAO extends DAOImpl<Account> implements DAO<Account> {
}
MVC Controller:
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
//System.out.println("is null? " + sessionFactory);
AccountDAO dao = new AccountDAO();
Account account = new Account();
account.setUsername("hello");
account.setPassword("test");
dao.save(account);
model.addAttribute("message", "Hello world!");
return "hello";
}
}
I've searched thru StackOverflow and Google but I cannot find anything that helps.
I've tried using a Transaction on DAOImpl.save(T t) but it still has the same issue.
public T save(T t) {
Transaction tr = getSession().getTransaction();
tr.begin();
getSession().persist(t);
tr.commit();
return t;
}
Annotations are not inherited.
Add the transactional annotation to the concrete dao, not the abstract class.
