this is my controller

query.setString("ID", docID);
List<Staff> DocDetailsList = castlist(Staff.class,query.list());
tx.commit();
return DocDetailsList;

In your hbm file, there are "timestamp" column type. Let hibernate guess the column type:
<property name="createDate" column="CreateDate" />
In other words, if you have the following property:
java.util.Date createDate;
hibernate3-maven-plugin hibernate3:hbm2ddl goal will create the following column in MySql:
`CreateDate` datetime DEFAULT NULL
Note: datetime and timestamp have different ranges. Same for Java Long (timestamp) and java.util.Date.

if yes how did you resolve it? Please help me with issue.
I appreciate your responses in advance. Thank you!!!!!!!!!!!!!!

In your java code, change a name of many to one relation, to anything but the current:
#ManyToOne
#JoinColumn(name="BATCH_JOB_CONFIG_ID", referencedColumnName="BATCH_JOB_CONFIG_ID")
private BatchJobConfigDetails batchJobConfigDtl;
something like
#ManyToOne
#JoinColumn(name="MY_NEW_NAME", referencedColumnName="BATCH_JOB_CONFIG_ID")
private BatchJobConfigDetails batchJobConfigDtl;
and also change it in your hbm.xml file appropriately.
UPDATE:
Also, change a name of columns in your hbl.xml file. One second.
from
<many-to-one name="BatchJobConfigDetails" column="BATCH_JOB_CONFIG_ID"
class="BatchJobConfigDetails" not-null="true" />
to
<many-to-one name="BatchJobConfigDetails" column="MY_NEW_NAME"
class="BatchJobConfigDetails" not-null="true" />

In your mapping, you have this

But property labJoin has type int. The type of this property has to be Set<Laboratorio>.

How to resolve this issue "org.hibernate.AssertionFailure: null id in com.xxxxxx.Profiles entry (don't flush the Session after an exception occurs)?

How to resolve this issue org.hibernate.AssertionFailure: null id in com.xxxxxx.Profiles entry (don't flush the Session after an exception occurs)
I'm using hibernate and Mysql, I want to insert the data into a table of my database but I was unable to do it.
Thanks.
This is my Dao:
public class ProfilesDao {
public void addProfile(Profiles profile){
Transaction tx = null;
Session session = HibernateUtil.getSessionFactory().openSession();
try{
tx = session.beginTransaction();
session.save(profile);
session.getTransaction().commit();
} catch (Exception e){
e.printStackTrace();
if(tx != null){
tx.rollback();
}
} finally {
session.flush();
session.close();
}
}
}
This is my Bean:
public void addProfile(){
Profiles profiles = new Profiles(getProfileName(),getProfileDescription());
ProfilesDao profilesDao = new ProfilesDao();
profilesDao.addProfile(profiles);
}
This is my POJO:
#Entity
#Table(name="profiles"
,catalog="metaestudiante_project_v1"
, uniqueConstraints = #UniqueConstraint(columnNames="profile_name")
)
public class Profiles implements java.io.Serializable {

And this is my hbm.xml

<column name="profile_id" not-null="true" />
</key>
<one-to-many class="com.besolapp.model.pojos.Users" />
</set>
</class>
</hibernate-mapping>
All this looks like easy but I am getting an error:
org.hibernate.AssertionFailure: null id in com.besolapp.model.pojos.Profiles entry (don't flush the Session after an exception occurs)
Can anybody help me please?

Why am I getting org.hibernate.id.IdentifierGenerationException?

As I run my main class (Runner) program I get the following exception :
org.hibernate.id.IdentifierGenerationException: attempted to assign id
from null one-to-one property: country
I don't know the reason, why am I getting this exception.
The mapping xml :
<hibernate-mapping>
<class name="pojo.Country" table="country">
<id name="countryID" column="c_id">
<generator class="increment" />
</id>
<property name="countryName" column="c_name" />
<one-to-one class="pojo.PM" name="pm" cascade="all" />
</class>
<class name="pojo.PM" table="pm">
<id name="countryID" column="c_id">
<generator class="foreign">
<param name="property">country</param>
</generator>
</id>
<property name="pmName" column="pm_name" />
<one-to-one class="pojo.Country" name="country" constrained="true" />
</class>
</hibernate-mapping>
POJO Classes :
Country
public class Country {
private int countryID;
private String countryName;
private PM pm;
public PM getPm() {
return pm;
}
public void setPm(PM pm) {
this.pm = pm;
}
public int getCountryID() {
return countryID;
}
public void setCountryID(int countryID) {
this.countryID = countryID;
}
public String getCountryName() {
return countryName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
}
PM
public class PM {
private int countryID;
private String pmName;
private Country country;
public int getCountryID() {
return countryID;
}
public void setCountryID(int countryID) {
this.countryID = countryID;
}
public String getPmName() {
return pmName;
}
public void setPmName(String pmName) {
this.pmName = pmName;
}
public Country getCountry() {
return country;
}
public void setCountry(Country country) {
this.country = country;
}
}
and this is the class that tries to commit the transaction :
public class Runner {
public static void main(String args[]) {System.out.println("dfdf");
Configuration config = new Configuration().configure();
SessionFactory sessFact = config.buildSessionFactory();
Session session = sessFact.openSession();
Transaction trans = session.beginTransaction();
Country c = new Country();
PM pm = new PM();
pm.setPmName("Manmohan Singh");
c.setCountryName("India");
c.setPm(pm);
session.save(c);
trans.commit();
}
}
SQL that created table :
CREATE TABLE country(c_id INTEGER,c_name TEXT,PRIMARY KEY(c_id));
CREATE TABLE pm(c_id INTEGER,pm_name TEXT);

The problem is the country variable. You should initialize all the attirbutes before trying to do some transactions.
EDIT: In your Hibernate file, you want to generate the PM ID from the ID of the country property. However, this property has never been initialized.
<class name="pojo.PM" table="pm">
<id name="countryID" column="c_id">
<generator class="foreign">
<param name="property">country</param>
</generator>
</id>
<property name="pmName" column="pm_name" />
<one-to-one class="pojo.Country" name="country" constrained="true" />
</class>
So, add pm.setCountry(c); to your code.

hibernate returning null objects

i am new in using hibernate and for some reason i am getting a list of null objects when i am using the following code:
public static void main(String args[])
{
Session s = HibernateUtil.currentSession();
ArrayList lst = (ArrayList) s.createQuery("from Users").list();
for(Object obj : lst){
Users user = (Users)obj;
System.Out.println(user.getUserid()); // null
}
}
my hibernate mapping xml looks like this:
