I would like to create a simple table "account" using hibernate in an oracle database.
Here's my bean class Account:
#Entity
#Table(name = "account")
public class Account implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(nullable = false)
private String id;
#Column(nullable = false)
private String iban;
#Column(nullable = false)
private String name;
#Column(name = "`usage`", nullable = false)
private String usage;
#Column(nullable = false)
private String type;
#Column(nullable = false)
private String ccy;
#Column(nullable = false)
private String psuStatus;
#Column(nullable = false)
private String balances;
public Account() {
}
public Account(String id, String iban, String name, String usage,
String type, String ccy, String psuStatus, String balances) {
this.id = id;
this.iban = iban;
this.name = name;
this.usage = usage;
this.type = type;
this.ccy = ccy;
this.psuStatus = psuStatus;
this.balances = balances;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getIban() {
return iban;
}
public void setIban(String iban) {
this.iban = iban;
}
public String getUsage() {
return usage;
}
public void setUsage(String usage) {
this.usage = usage;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getCcy() {
return ccy;
}
public void setCcy(String ccy) {
this.ccy = ccy;
}
public String getPsuStatus() {
return psuStatus;
}
public void setPsuStatus(String psuStatus) {
this.psuStatus = psuStatus;
}
public String getBalances() {
return balances;
}
public void setBalances(String balances) {
this.balances = balances;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Account other = (Account) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
}

The problem is, when I run the app, it doesn't create the table account in the database. I used the same example with an MySQL JDBC driver and a wampserver and it worked perfectly. But with an Oracle driver, for some reason, it doesn't work. Anybody knows why?
UPDATE: I was able to display the error by setting the hbm2ddl logger to true, and here's what I have now:
java.sql.SQLException: Listener refused the connection with the following error:

Does this mean that I need to define the oracle schema?
UPDATE 2: Now I have this error:
14:29:58.026 [Default Executor-thread-12] ERROR org.hibernate.tool.hbm2ddl.SchemaExport - HHH000389: Unsuccessful: create table account (id varchar(255) not null, balances varchar(255) not null, ccy varchar(255) not null, iban varchar(255) not null, name varchar(255) not null, psuStatus varchar(255) not null, type varchar(255) not null, `usage` varchar(255) not null, primary key (id)) ENGINE=InnoDB
14:29:58.027 [Default Executor-thread-12] ERROR org.hibernate.tool.hbm2ddl.SchemaExport - ORA-00911: invalid character
But what's strange is that I'm generating the query using Hibernate. I didn't write the query myself.

I am working on a Spring application which has a persistence unit configured in the application-context.xml. I need to add an additional package in in order to use new entities.
Even though this part of the persistence.xml file looks like below, my entities from the additional package are not seen by the application and I get an exception saying that the entity is unknown.
<bean id="transactionManager_students" class="org.springframework.orm.jpa.JpaTransactionManager">

#PersistenceContext(unitName = "unit_stud")
public EntityManager em;
public Student student;
#Transactional(value = "clientTransaction", propagation = Propagation.REQUIRED)
public long persistStudentObject() {
long studentId = 0;
try
{
logger.debug("Start Persisting...");
em.persist(student);
// unique ID
studentId = student.getId();
logger.debug("Persisting OK...");
}
catch (PersistenceException persistenceException)
{
logger.error("PersistenceException occur", persistenceException);
}
}
return studentId ;
}
The entity:
package com.students.entity;
#Entity
#Table(name = "STUDENTS", schema = "DEMO", catalog = "")
public class Student{
private long id;
private String firstname;
private String name;
private String streetnumber;
private String zipcodecity;
Can anyone help me? I do not know what to do in order to make my entities visible.
when i am going to execute this program.
my program is successfully executed but it doesn't store data in database.
what is the problem in this program.

In this configuration you are missing transaction management configuration. Use #transactional annotation over your service method.
In you situation data is not committing in the database it just save the data and not commit the data in database.
Our current development based on Discriminator model in Multi-tenancy. Following is the technical stack we are currently engage with,
Spring 3.1.1.RELEASE
Hibernate 4.1.6.Final
We are maintain tenant id by keep one column separately in each table. Tenant id filter when session is created.
Example model class.
#Entity
#FilterDef(name = "tenantFilter", parameters = #ParamDef(name = "tenantIdParam", type = "string"))
#Filters(#Filter(name = "tenantFilter", condition = "tenant_id = :tenantIdParam"))
#Table(name = "assessment")
public class Assessment implements java.io.Serializable, Comparable<Assessment> {
private static final long serialVersionUID = -2231966582754667029L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", unique = true, nullable = false)
private Long id;
#Column(name = "tenant_id", nullable = false, updatable = false)
private String tenantId;
// rest of the code...
}
This is the configuration of session factory

return assessment.getId();
} catch (HibernateException e) {

session.getTransaction().rollback();
return null;
} finally {
session.close();
}
}
}
I would like to know is there a way to get the spring transaction support with this Discriminator model for database transactions ?
And the other thing is I would like to know is there any advantage of give transaction handling to spring rather than handling it by our side?
Thanks in advance.
i had similar problem and i have resolved it using aspect instead of customizing sessionfactory, so i can leverage annotation driven transaction support
Below code is for aspect which works on annotation #Tennant
#Aspect
public class TennantAspect {
#Autowired
private SessionFactory sessionFactory;
#Around("#annotation(Tennant)")
public Object enableClientFilter(ProceedingJoinPoint pjp) throws Throwable {
Object obj;
boolean isDAO=(pjp.getTarget() instanceof BaseDAO<?,?>);
try {
if(isDAO){
Authentication auth=SecurityContextHolder.getContext().getAuthentication();
if(auth!=null){
User user=(User) auth.getPrincipal();
this.sessionFactory.getCurrentSession().enableFilter("clientFilter").setParameter("clientId", user.getClientId());
}
}
obj=pjp.proceed();
}finally {
if(isDAO)
this.sessionFactory.getCurrentSession().disableFilter("clientFilter");
}
return obj;
}
}
Hope this solves your problem.
Alternatively you can also look at tenancy support by hiberante & spring

I'm using Spring 3.1.0.RELEASE with Hibernate 4.0.1.Final. I'm trying to use the Spring transaction manager but am having an issue where Spring is returning old data for a find method. In my Spring application, I call a save method, and then a find method. After I call save, I can see the changes in the database, but when I call the find, it is returning the old state of the object. Here is the controller methods ...
// method to save
#RequestMapping(method = RequestMethod.POST)
public String saveUserEventFeeds(final HttpServletRequest request,
#ModelAttribute("eventFeeds") final Set<EventFeed> eventFeeds) {
final String nextPage = "user/eventfeeds";
try {
final String[] eventFeedIds = request.getParameterValues("userEventFeeds");
final Set<EventFeed> userEventFeeds = new HashSet<EventFeed>();
if (eventFeedIds != null) {
for (final String eventFeedId : eventFeedIds) {
final EventFeed eventFeed = getEventFeed(eventFeeds, Integer.parseInt(eventFeedId));
userEventFeeds.add(eventFeed);
} // for
} // if
final Registration currentUser = (Registration) securityContextFacade.getContext().getAuthentication().getPrincipal();
userService.saveUserEventFeeds(currentUser.getId(), userEventFeeds);
} catch (Exception exc) {
LOG.error(exc.getMessage(), exc);
} // try
return nextPage;
} // saveUserEventFeeds
// method to retrieve user
#ModelAttribute("user")
public UserDetails getUser() {
final Registration reg = (Registration) securityContextFacade.getContext().getAuthentication().getPrincipal();
final int id = reg.getId();
final Registration foundUser = userService.findUserById(id);
return (UserDetails) foundUser;
} // getUser
and here is the service where i declare everything transactional ...
#Transactional(rollbackFor = Exception.class)
#Component("userService")
public class UserServiceImpl implements UserService {
...
#Override
public void saveUserEventFeeds(Integer userId, Set<EventFeed> eventFeeds) {
final Registration searchUser = new Registration();
searchUser.setId(userId);
final Registration user = usersDao.getUser(searchUser);
if (user != null) {
user.setUserEventFeeds(eventFeeds);
usersDao.saveUser(user);
} else {
throw new RuntimeException("User with id " + userId + " not found.");
} // if
}
#Override
public Registration findUserById(Integer id) {
final Registration searchUser = new Registration();
if (id != null) {
searchUser.setId(id);
} // if
return usersDao.getUser(searchUser);
}
Below is the transaction manager I've declared in my application context file. If you can see how I can configure things differently so that I can get the most current data on my finds, please let me know.
