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 {
private Short profileId;
private String profileName;
private String profileDescription;
private Set userses = new HashSet(0);
public Profiles() {
}
public Profiles(String profileName, String profileDescription) {
this.profileName = profileName;
this.profileDescription = profileDescription;
}
public Profiles(String profileName, String profileDescription, Set userses) {
this.profileName = profileName;
this.profileDescription = profileDescription;
this.userses = userses;
}
#Id #GeneratedValue(strategy=GenerationType.AUTO)
#Column(name="profile_id", unique=true, nullable=false)
public Short getProfileId() {
return this.profileId;
}
public void setProfileId(Short profileId) {
this.profileId = profileId;
}
#Column(name="profile_name", unique=true, nullable=false, length=15)
public String getProfileName() {
return this.profileName;
}
public void setProfileName(String profileName) {
this.profileName = profileName;
}
#Column(name="profile_description", nullable=false, length=140)
public String getProfileDescription() {
return this.profileDescription;
}
public void setProfileDescription(String profileDescription) {
this.profileDescription = profileDescription;
}
#OneToMany(fetch=FetchType.LAZY, mappedBy="profiles")
public Set getUserses() {
return this.userses;
}
public void setUserses(Set userses) {
this.userses = userses;
}
}
And this is my hbm.xml
<hibernate-mapping>
<class name="com.besolapp.model.pojos.Profiles" table="profiles" catalog="metaestudiante_project_v1" optimistic-lock="version">
<id name="profileId" type="java.lang.Byte">
<column name="profile_id" />
<generator class="identity" />
</id>
<property name="profileName" type="string">
<column name="profile_name" length="15" not-null="true" unique="true" />
</property>
<property name="profileDescription" type="string">
<column name="profile_description" length="140" not-null="true" />
</property>
<set name="userses" table="users" inverse="true" lazy="true" fetch="select">
<key>
<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?

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.

Updating nested field using JSP and Spring

Good evening all,
I am trying to update a field in my page and keep getting an exception thrown.
I have a main object "car" that has a foreign key to "Model"
when I built my page I created a select box to list all the models. So now when I choose a model and submit the form I get the exception thrown below. All of the fields that are in the Car table update fine as long as I do not include the model field. Once I try to include the model field, code breaks on submitting.
org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/sellcar.jsp at line 28
25: <c:forEach items="${cars}" var="car">

JSP code: (I did not include all but only what is necessary)
<spring:bind path="command.model">
<select name='<c:out value="${status.expression}"/>'>
<option value=""></option>
<c:forEach items="${cars}" var="car">
<option value='<c:out value="${car.model.modId}"/>'
<c:if test="${car.model.model == status.value.model}">SELECTED</c:if>>
<c:out value="${car.model.model}" />
</option>
</c:forEach>
</select>

I got it fixed. It seems I had to add the foreign key property in the Car.hbm along with adding the foreign keys variables, getters and setters to Car.

Based on the error message you might want to change line 28 from:
status.value.model
to
status.value

First is the main method 2nd the class to be persitet and 3rd the hibernate mapping for the class. This is the error message:
843 [main] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: -104, SQLState: 23505
843 [main] ERROR org.hibernate.util.JDBCExceptionReporter - integrity constraint violation: unique constraint or index violation; SYS_PK_10585 table: MEAL

You declared that you want to assign values to id property manually (<generator class="assigned" />), but don't actually assign it.
So, you need to assign the value manually or declare different id generation strategy.

Hibernate mapping and query

The hibernate mapping of my hbm.xml is:
<class name="UserCalendar" table="user_calendar">

public List<UserDate> getUserDates() {

The UserDate.java:

}
Now I want to select those UserCalendar object which has a specific itemId. In my thought if I insert userCalendarId in UserItem and execute
SELECT USERCALENDAR
FROM USER_CALENDAR
WHERE USERCALENDAR.USERCALENDARID IN
(SELECT USERCALENDARID
FROM USERITEM
WHERE USERITEM.ITEMID=ID)
then it might be possible.
Am I right?
How can I insert userCalendarId in UserItem? What is the mapping needed for this?
Thanks and regards.

To have one-to-many you will need column in UserDate that refers to UserCalendar.userCalendarId and column in UserItem to refer to UserDate.userDateId. You will need to specify those columns via many-to-one in those classes.
Then you can use join
SELECT * FROM user_calendar uc
JOIN user_date ud ON ud.user_calendar_id=uc.user_calendar_id
JOIN user_item ui ON ui.user_date_id=ud.user_date_id
WHERE ui.user_item_id=<your value>
Assuming that you have those new columns user_calendar_id and user_date_id in user_date and user_item.
In HQL it will be simpler but I don't remember on top of my head. Check docs.
It could be something like
select ui.userDate.userCaledar from UserItem ui where ui.userItemId=:id
Provided that you added properties userDate and userCalendar via many-to-one
