JPA Annotations

JPA defines dozens of annotations that can be divided into the following groups:

Annotations for JPA aware classes:

• JPA Annotations for Classes
• JPA Annotations for JPQL Queries

Annotations for fields in JPA persistable classes:

• JPA Annotations for Fields
• JPA Annotations for Relationships

Annotations for additional JPA configuration:

• JPA Annotations for Access Modes
• JPA Annotations for Value Generation

Annotations for JPA lifecycle event callbacks:

• JPA Annotations for Callback Methods

Java EE container annotations:

• JPA Annotations for Java EE

Many other JPA annotations are designated for Object Relational Mapping (ORM) JPA providers (for mapping between a relational database and an object model and for direct SQL queries):

• JPA Annotations for Mapping (ORM)
• JPA Annotations for SQL Queries

These ORM annotations are silently ignored by ObjectDB.
