with reference to the coding example in the posting instructions and many of your other examples posted in the forums. While I appreciate the recommended coding style as shown makes for convenient minimal examples ... for entities, compliant entity classes belong in separate files. Secondly, in many forum posting examples

these manual pages . We do not have specific NetBeans examples in addition to  the tutorials ... and Transactions? I'm finding these examples : http://www.objectdb.com/java/jpa/persistence/crud difficult as they don't really give a full example of what to do. This makes it difficult as

Following previous questions on the subject I'd like to share a simple working example of ObjectDB and Spring Boot. The code of the  example can be found here: https://github.com/kirshamir/spring-data-jpa-objectdb  The example uses the automatic query generation performed by

you for your quick reply. But thats a maven example . If i place the object-jee.jar to th /Web-inf/lib ... examples have been updated and tested successfully with TomEE 1.7.2 and ObjectDB 2.6.2_02. support Support

The maven plugin example here is incomplete:  https://www.objectdb.com/java/jpa/tool/enhancer#Maven_and_ANT_Enhancement_ Taken literally it can't work because it's missing this:     ... ; May I suggest you also link from there to the tutorial example :  https://www.objectdb.com

Hello! Where can I find classes for example database world.odb? Thanks for the answer.   Robin_2005 Kompan Serge The source code of the relevant entity classes is attached. support Support ... the relationships OneToMany and ManyToMany? I want to see a working example :-) Robin_2005 Kompan Serge

specified. In this example , the parent entity has simple primary key: @Entity public class Employee

. Example : Concrete class as a mapped superclass @MappedSuperclass public class Employee { @Id

is retrieved for the constructed object. Example : Query q = em.createNativeQuery( "SELECT c.id, c.name

can be included in the query result by specifying this annotation in the metadata. Example : Query q = em

may be used to override mappings declared or defaulted by the embeddable class. Example : @Embedded

to DiscriminatorType.STRING . Example : @Entity @Table(name = "CUST") @Inheritance(strategy = SINGLE_TABLE

. The CollectionTable annotation specifies a mapping to a database table. Example : @Entity public class

, should be specified for each concrete entity class in the hierarchy. Example : @Entity @Table(name = "CUST

. Example : Query q = em.createNativeQuery( "SELECT o.id, o.quantity, o.item, " + "i.id, i.name, i

is permitted to eagerly fetch data for which the LAZY strategy hint has been specified. Example

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.FieldResult Implemented Interfaces: Annotation Used in conjunction with the EntityResult annotation to map columns specified in the SELECT list of a SQL query to the properties or fields of an entity class. Example : Query q = em

to be EnumType.ORDINAL . Example : public enum EmployeeStatus {FULL_TIME, PART_TIME, CONTRACT} public enum

. Example : enum Status { OPEN(0), CLOSED(1), CANCELLED(-1); @EnumeratedValue final int intValue; Status(int

to avoid the use of Path variables. For example : CriteriaQuery q = cb.createQuery(Person.class); Root p

the use of Path variables. For example : CriteriaQuery q = cb.createQuery(Person.class); Root p = q.from

of Path variables. For example : CriteriaQuery q = cb.createQuery(Person.class); Root p = q.from

the Path.get operation in order to avoid the use of Path variables. For example : CriteriaQuery q = cb

the use of Path variables. For example : CriteriaQuery q = cb.createQuery(Person.class); Root p = q.from

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.UniqueConstraint Implemented Interfaces: Annotation Specifies that a unique constraint is to be included in the generated DDL for a primary or secondary table. Example : @Entity @Table( name = "EMPLOYEE", uniqueConstraints

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.Transient Implemented Interfaces: Annotation Target: Method, Field Specifies that the annotated property or field is not persistent. May annotate a property or field of an entity class, mapped superclass, or embeddable class. Example

.get operation in order to avoid the use of Path variables. For example : CriteriaQuery q = cb.createQuery

from a get or join operation and the query result type is specified. For example : CriteriaQuery q = cb

the Path.get operation in order to avoid the use of Path variables. For example : CriteriaQuery q = cb

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.AttributeOverrides Implemented Interfaces: Annotation Target: Type, Method, Field Used to override mappings of multiple properties or fields. Example : @Embedded @AttributeOverrides({ @AttributeOverride(name = "startDate", column

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.AssociationOverrides Implemented Interfaces: Annotation Target: Type, Method, Field Used to override mappings of multiple relationship properties or fields. Example : @MappedSuperclass public class Employee { @Id protected Integer id

, the default values of the CollectionTable annotation elements apply. Example : @Embeddable public class

table of the superclass. Example : Customer and ValuedCustomer subclass @Entity @Table(name = "CUST

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.PrimaryKeyJoinColumns Implemented Interfaces: Annotation Target: Type, Method, Field Groups PrimaryKeyJoinColumn annotations. It is used to map composite foreign keys. Example : ValuedCustomer subclass @Entity @Table(name = "VCUST

SequenceGenerator annotation. Example : @SequenceGenerator(name = "EMP_SEQ", allocationSize = 25

Jakarta Persistence (JPA) Annotation Type jakarta.persistence.SqlResultSetMapping Implemented Interfaces: Annotation Target: Type Specifies a mapping of the columns of a result set of a native SQL query or stored procedure. Example : Query q = em.createNativeQuery( "SELECT o.id AS order_id, " + "o

the ElementCollection annotation when the element collection value is of such a temporal type. Example

is specified for an entity class, the default values apply. Example : @Entity @Table(name = "CUST", schema

how the native SQL query result set should be interpreted, for example : @NamedNativeQuery( name

.createNamedQuery . The following is an example of the definition of a named query written in

column value for the first element is 0 . Example : @Entity public class CreditCard { @Id long

to avoid the use of Path variables. For example : CriteriaQuery q = cb.createQuery(Person.class); Root

Jakarta Persistence (JPA) Method in jakarta.persistence.MapKeyColumn int length (Optional) The column length. Applies only to columns whose type is parameterized by length, for example , varchar or varbinary types. Default: 255 Since: Jakarta Persistence (JPA) 1.0

Jakarta Persistence (JPA) Method in jakarta.persistence.Convert String attributeName A name or period-separated path identifying the converted attribute relative to the annotated program element. For example : if an entity class is annotated @Convert(attributeName = "startDate

Jakarta Persistence (JPA) Method in jakarta.persistence.Column int length (Optional) The column length. Applies only to columns whose type is parameterized by length, for example , varchar or varbinary types. Default: 255 Since: Jakarta Persistence (JPA) 1.0

and the query result type is specified. For example : CriteriaQuery q = cb.createQuery(String.class); Root
