JPA-Hibernate Join table Inheritance cannot query subclass

I am trying to query the subclass by the parent attributes. However hibernate always try to map the query result to parent class.
Framework used: JPA 2.0, Hibernate 3, Spring 3
Exception thrown:
org.springframework.orm.hibernate3.HibernateObjectRetrievalFailureException: Object with id: com.hkbea.zpm.entity.PositionPk#1dee9de was not of the specified subclass: com.hkbea.zpm.entity.FundPosition (loaded object was of wrong class class com.hkbea.zpm.entity.Position); nested exception is org.hibernate.WrongClassException: Object with id: com.hkbea.zpm.entity.PositionPk#1dee9de was not of the specified subclass: com.hkbea.zpm.entity.FundPosition (loaded object was of wrong class class com.hkbea.zpm.entity.Position)

I've tried to change the parent class to abstract, but hibernate will throw exception for failed to instantiate object of abstract class.
Caused by: org.hibernate.InstantiationException: Cannot instantiate abstract class or interface: com.hkbea.zpm.entity.Position
I've also searched some other post said, the cascade mode need to be set for many-to-one property. So i have tried but still not working.
Query:
(List<FundPosition>) sessionFactory.getCurrentSession()
.createQuery("from FundPosition where activeFlag='A' and accountNumber=?")
.setString(0, accountNumber)
.list();

how to handle ERROR: Duplicate entry in spring jpa

I was trying to execute below code :
public void createScarceVouchers(long numberOfVouchers,int productId,String fileType,int userId) {
EntityManager entityManager=this.emf.createEntityManager();
try {
entityManager.setFlushMode(FlushModeType.COMMIT);
Product product = productService.getProductById(productId);
UserMaster userMaster = userMasterService.getOrignalUserMasterById(userId);
entityManager.getTransaction().begin();
int batchSize = 30;
for(int i=0;i<100;i++) {
Voucher voucher = null;
String strVoucher = AcfUtils.getRandom();
if(i>=2 && i<=5) {
strVoucher = "abcdefg";
System.out.println(i+"> abcdefgh");
voucher = new Voucher(product, userMaster, strVoucher, 'G',new Date());
}
else {
System.out.println(i+"> "+strVoucher);
voucher = new Voucher(product, userMaster, strVoucher, 'G',new Date());
}
entityManager.persist(voucher);
if (i % batchSize == 0 && i > 0) {
entityManager.flush();
entityManager.clear();
}
}
entityManager.getTransaction().commit();
}
catch(Exception ex) {
ex.getMessage();
}
finally {
entityManager.close();
}
}
And I was getting below exception.

I intentionally wanted this exception. Means, I was storing some keys to my Map collection. And if there exists the same key in DB then I wanted to remove that particular key from map.
So here I wanted to collect abcdefg from exception so that I can remove it from Map. Also this exception/error is marked in red color. How can I handle it to collect that value in my catch block.

From what it looks like your voucherStr is a key field and in your code it is not unique between 2-5(inclusive), which could be the cause of this exception.

Embedded Sqlite database with Ormlite and JavaFX: error creating table

I am trying to persist some data in my JavaFX application.
My code fails when attempting to create a table in my PersistenceManager class:
private final static String DATABASE_URL = "jdbc:sqlite:my.db";
private final static String DATABASE_DRIVER = "org.sqlite.JDBC";
// ...
Class.forName(DATABASE_DRIVER);
DriverManager.getConnection(DATABASE_URL);
connectionSource = new JdbcConnectionSource(DATABASE_URL);
// here it fails:
TableUtils.createTable(connectionSource,MyClass.class);
A file my.db is actually created, but it is empty. When executing TableUtils.createTable, it triggers the following:

My Class is this:

public class MyClass {
#DatabaseField(id = true)
private String nome;
#ForeignCollectionField(eager = false)
private Collection<MyOtherClass> risposte;
protected MyClass() {
super();
}
}
and MyOtherClass is:
#DatabaseTable(tableName = "myotherclass")
public class MyOtherClass {
#DatabaseField(id = true)
private String nome;
#DatabaseField(foreign = true)
private MyClass scheda;
protected MyOtherClass() {
super();
}
}
I am using ormlite-core-4.49-SNAPSHOT.jar.
What should I look for correcting this?

For me solution has been to switch to ormlite-core-4.48. Same version for ormlite-jdbc driver. Now it works correctly.

Thanks in advance.

In some cases this error is also caused when you use JDK 8 java.time.LocalDateTime with hibernate and don't have a Converter for this registered. (This is not the case in the OP's question, but other people might stumble about this.)

Looks like Hibernate try to deserialize a column that holds not serialized data. Hibernate thinks that this column has VARBINARY format. I think it is Timestamp property or other object property. Try to comment all columns in Facilities and Images except id and hotels.

You can use java SQL Date for date option and try again. Basically it happens sometimes when you try to convert date. So you can try with java SQL Date.
