Explore Jakarta EE, the cloud-native evolution of Java EE under the Eclipse Foundation. Learn to use Jakarta APIs to build a simple to-do app with Java.
Model a todo entity in Jakarta EE as a pojo with task, due date, created date, completed and archive flags, then annotate it as a jpa entity.
Learn how to mark a field as transient with the @Transient annotation to keep it out of database mapping, and model a one-to-many relationship between ToDo and user entities.
Map Java objects to relational database tables with JPA inheritance by using an abstract entity with common fields inherited by subclasses; avoid complex inheritance due to performance penalties.
Implement and map JPA inheritance with an abstract entity and map superclass to share audit fields, a common primary key, and persistence unit considerations across subclasses.
Define the persistence unit in a Jakarta EE app by configuring persistence.xml with a JTA transaction type, exclude-unlisted-classes, and database creation properties, including an in-memory database for development.
Activate CDI in jakarta ee by configuring beans.xml to set discovery to all. This enables CDI injection for non-annotated classes and helps manage application-scoped beans.
Define and expose a rest resource class for todos in Jakarta EE, inject a query service, and return a json list of todos at a configured path using producers.
