Hibernate: Program run persists new created entities together with entities which were persisted in previous program run and which I had deleted

This is maybe a beginner question on hibernate. I am doing my first steps, I designed a simple datamodel consisting of about 10 entities and I use hibernate to persist them to my Oracle XE database. Now I am facing the following problem: First time, when I do a transaction to persist some entities, they are persisted properly. I verify, that the data exists in the database and then I delete all the entries from all database tables. I verify that all tables are empty again. Then I run my program again to persist some new entities - and here happens something really strange: Afterwards I find in my databse the new entries as well as the old ones, which were persisted last time and which I had deleted! They contained the old IDs and the old data fields! How can this be? This happens even if I shut down my computer after the first time the program runs! How does it remember the old entries and where are they saved? Do you have any ideas?
Some information, that might be useful:
I am using annotations (instead of config files) for the mapping.
Following you see the classes used for persisting as well as one example of an entity (I am showing only one entity to avoid making the question too long).
As you see, I am using FetchType = EAGER on my MANY to MANY mappings (as I understand, this makes sure, that all related entities are loaded immediately together with any loaded entity). Can this have any impact?
Thanks for any help!

public void addForeignLanguage(Language language) {foreignLanguages.add(language);}
public Set<Language> getForeignLanguages() {return Collections.unmodifiableSet(foreignLanguages); }
}

Clarified by the comment of Jagger (see comments). Indeed, I was using Oracle SQL command line to delete the entries and I had rgotten, that I need to explicitely commit after deleting. The solution can be so easy :)

ORM in Morphia for a Nested Class

My Json document in the Morphia DB looks like this -
{
"_id" : ObjectId("58fcdf7e"),
"status" : "ACTIVE",
"user" : {
"id" : NumberLong(228),
"email" : "testing#domian.com"
}
}
I have created a Java class for this collection which looks like this -
#Entity("member_offer")
public class MemberOffer {
#Id
private ObjectId objectId;
#Property("status")
private String status;
#Embedded("user")
private UserDetail user;
#Embedded
class UserDetail {
#Property("id")
public long memberId;
#Property("email")
public String email;
UserDetail() {
}
}
public ObjectId getObjectId() {
return objectId;
}
public void setObjectId(ObjectId objectId) {
this.objectId = objectId;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public UserDetail getUser() {
return user;
}
public void setUser(UserDetail user) {
this.user = user;
}
}
Now when I am trying to fetch the data I am getting this exception -
java.lang.RuntimeException:
org.mongodb.morphia.mapping.MappingException: No usable constructor
for vo.MemberSubscription$UserDetail
Caused by: org.mongodb.morphia.mapping.MappingException: No usable
constructor for vo.MemberSubscription$UserDetail
Caused by: org.mongodb.morphia.mapping.MappingException: No usable constructor for vo.MemberSubscription$UserDetail
Caused by: java.lang.NoSuchMethodException: vo.MemberSubscription$UserDetail.()
Any idea how I can resolve this issue? I want UserDetail to be nested class only, I know if I create it as an independent class this error can be resolved. But my question here is can something like this (having nested class) can be achieved in Morphia?
Also if there is some fundamental flaw in my design please educate me about it.

You should try to use public modifier for the constructor, also make UserDetail (inner class) is static.

DB Collection:

Only for clarifying purposes. I do not pretend this to be a definitive answer.
Maybe you have misunderstood me. You must respect java naming conventions for beans.
#Document(collection="employee-territories")
public class EmployeeTerritory {
#Id
private ObjectId id;
#Field
private String EmployeeID;
#Field(value="TerritoryID")
private Integer TerritoryID;
// setters and getters
}
Should be
#Document(collection="employee-territories")
public class EmployeeTerritory {
#Id
private ObjectId id;
#Field
private String employeeID;
#Field(value="TerritoryID")
private Integer territoryID;
// setters and getters
}
It may, I repeat, it may be the reason of your exception.

I was able to resolved this errors. Please see my code snippet below. As per spring data mongo docs (Refer section 12.1.1): http://docs.spring.io/spring-data/mongodb/docs/current/reference/html/
Your Mongo DB fields are using camel case letters and it's respective setters and getters, but as per doc "The default field name for identifiers is '_id' and can be customized via the #Field annotation."
For Ex: #Field('x') String id
Resulting Id-Fieldname in MongoDB ==> x,
Similar logic you need to apply for all your field if you're willing to get data by any field(s).
Use below and will work.
#Document(collection="employee-territories")
public class EmployeeTerritory {
#Id
private ObjectId id;
#Field("EmployeeID")
private Integer employeeID;
#Field("TerritoryID")
private Integer territoryID;
public ObjectId getId() {
return id;
}
public void setId(ObjectId id) {
this.id = id;
}
public Integer getEmployeeID() {
return employeeID;
}
public void setEmployeeID(Integer employeeID) {
this.employeeID = employeeID;
}
public Integer getTerritoryID() {
return territoryID;
}
public void setTerritoryID(Integer territoryID) {
this.territoryID = territoryID;
}
}

Class instance in the heap

I try to create a simple JPA application based on spring framework and Eclipselink JPA.
First of all initialize an EntityManagerBean:
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws Exception {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setJpaDialect(new EclipseLinkJpaDialect());
EclipseLinkJpaVendorAdapter vendorAdapter = new EclipseLinkJpaVendorAdapter();
vendorAdapter.setShowSql(true);
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setDatabasePlatform("org.eclipse.persistence.platform.database.PostgreSQLPlatform");
entityManagerFactoryBean.setJpaVendorAdapter(vendorAdapter);
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPackagesToScan("org.egzi.diplom.model");
entityManagerFactoryBean.setLoadTimeWeaver(new SimpleLoadTimeWeaver());
//to update existing table (alter table)+
Properties additionalProperties = new Properties();
additionalProperties.setProperty("eclipselink.ddl-generation", "create-or-extend-tables");
additionalProperties.setProperty("eclipselink.ddl-generation.output-mode","database");
entityManagerFactoryBean.setJpaProperties(additionalProperties);
return entityManagerFactoryBean;
}
And in a DAO class a try to persist some entity:
#PersistenceContext
EntityManager entityManager;
#Transactional(propagation = Propagation.REQUIRED)
public void createTODO() {
Todo todo = new Todo();
todo.setSummary("a");
todo.setDescription("b");
entityManager.persist(todo);
}
And entity class:
#Entity
public class Todo {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String summary;
private String description;
public String getSummary() {
return summary;
}
public void setSummary(String summary) {
this.summary = summary;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
#Override
public String toString() {
return "Todo [summary=" + summary + ", description=" + description
+ "]";
}
}
but when i run such code i have an exception:
java.lang.IllegalArgumentException: Object: Todo [summary=a, description=b] is not a known entity type.

and when i look into a eclipselink sources i find HashMap with Class as a key:
org.eclipse.persistence.internal.sessions.AbstactSession.getDescriptor(Class):
descriptor = this.descriptors.get(theClass);
When i started to debug my code i find that descriptors map already have a key of Todo.class. And i find that identityHash of class in HashMap and Todo.class is a different. I start my code from Inteliji IDEA.
What's wrong in my example?
UPDATE:
find that classes in descriptors HashMap have a link on org.springframework.instrument.classloading.SimpleInstrumentableClassLoader#14bb2297
but my Todo object have another one:
sun.misc.Launcher$AppClassLoader#58644d46

Try to add getter and setter for field ID too!

Fix exception by setting another LoadTimeWeaver - InstrumentationLoadTimeWeaver and exception is gone

any help are appreciated
Thank you for your help

In short, methods of EntityManager such as persist, remove, merge must be called inside a transaction, hence the error message which is actually self explaining:
javax.persistence.TransactionRequiredException: no transaction is in progress
Spring provides support for transaction management (see links below), including when writing tests... if you use one of the Spring testing class providing transactional support.
