jpa-2.1

I am migrating my application to Hibernate 5 from Hibernate 3. We are using DatabaseMetadata class to get TableMetadata . Hence using TableMetadata object to get DB table column information like column size, type..etc. It seems in Hibernate 5 DatabaseMetadata class got deprecated (removed!). Are there any alternatives for DatabaseMetadata class in Hibernate 5? Or else how to get TableMetadata in Hibernate 5 env? It got removed in 5.0 as we moved to a new approach to schema tooling. DatabaseMetadata represented the existing catalog/schema information from the underlying database. In 5.0 that

I'm using Hibernate 4.3.8.FINAL and have the following model where a Department has many Employees, and an Employee can be a Manager. Manager has a set of Foo which can be either Foo or Bar. The Employee entity: @Entity @Table(name = "employee", schema = "payroll") @Inheritance(strategy = InheritanceType.JOINED) public class Employee { @Id private Long id; @Basic(optional = false) @Column(name = "name") private String name; @JoinColumn(name = "department_id", referencedColumnName = "id") @ManyToOne(optional = false, fetch = FetchType.LAZY) private Department department; } The Manager entity:

The following database schema: Employee[EMP_ID (PK), name, salary] Phone[ID (PK), number_str, OWNER_ID (FK)] Employee_aud[EMP_ID (PK), REV (PK/FK), REVTYPE, name, salary] Phone_aud[ID (PK), REV (PK/FK), REVTYPE, number_str] Employe_phone_aud[REV(PK/FK), OWNER_ID(PK/FK), REVTYPE(PK/FK)] can be expressed with the following Java Entities: Employee : @Entity @Audited public class Employee { @Id @GeneratedValue @Column(name = "EMP_ID") private long id; @Column private String name; @Column private int salary; @OneToMany @JoinColumn(name = "OWNER_ID", referencedColumnName = "EMP_ID") private final

Everything worked fine until I added toSting() in my entity classes. After which I start getting the following error in runtime: Exception in thread "main" java.lang.StackOverflowError at java.lang.AbstractStringBuilder.append(Unknown Source) at java.lang.StringBuilder.append(Unknown Source) at java.lang.StringBuilder.<init>(Unknown Source) at entity.Guide.toString(Guide.java:51) at java.lang.String.valueOf(Unknown Source) at java.lang.StringBuilder.append(Unknown Source) at entity.Student.toString(Student.java:45) ... @Entity public class Teacher { @Id @GeneratedValue(strategy=GenerationType

I am not having any idea how to use Enum in @ColumnResult Type while using @ConstructorResult of @SqlResultSetMapping @SqlResultSetMapping(name="DetailAndResult", classes={ @ConstructorResult(targetClass=DetailAndResult.class, columns={ @ColumnResult(name="id", type= String.class), @ColumnResult(name="runId", type=Integer.class), @ColumnResult(name="subRunId", type=Integer.class), @ColumnResult(name="transactionId", type=Integer.class), @ColumnResult(name="referenceNumber", type=String.class), @ColumnResult(name="customerName", type=String.class), @ColumnResult(name="transactionType", type

I'm trying to migrate an application from Hibernate 3.4.0.GA to Hibernate 5.1, and after complete the required changes on java code, when I deploy the application I'm watching how Hibernate is trying to create HT_ tables (global temporary), one for each @Inheritance annotated entity. Searching on Google I've found why the tables are being created. But in my case we are not allow to change de database to add new tables. My Inheritance model only has one level of Inheritance and its simple, example Does anyone knows any alternative representation for a hierarchical table structure that I can use

On JavaEE environment, I use JPA 2.1 implementation with EclipseLink, I have some entities that contain enums . So I have created converters for these enumerations. Car entity : @Entity public class Car implements Serializable { private static final long serialVersionUID = 6L; @Id private String id; @Convert (converter = CarColorConverter.class) private CarColor color; public enum CarColor { Black, Gray, White, Red }; public Car () { id = GenerateUUID.id (); } .... } CarColor Converter : @Converter (converterClass = CarColorConverter.class, name = "CarColorConverter") public class
