Creating New Jakarta Persistence/JPA Applications
Java Enterprise Edition (Java EE) has gone through a major transformation and is now Jakarta EE. One of the most significant changes impacting developers is the namespace change from javax to jakarta. If you're new to JPA or creating new JPA applications, you might be wondering how to create your persistence applications. Your two options are: Create your new applications using the new jakarta namespace (Jakarta Persistence 3.0). Create your new applications using the existing javax namespace (JPA 2.2 and earlier). If you're writing a new application, you might think that option 1 is the ob
Creating a Simple JPA Application
In this blog, we're going to look at how to create a simple JPA application in IntelliJ IDEA Ultimate. JPA allow you to store, access and manage Java objects in a relational database. If you want to create a Jakarta Persistence application with the new jakarta namespace, checkout this version of the blog or watch this video. Creating a new JPA Project First, we'll create a new project in IntelliJ IDEA Ultimate by clicking on the New Project button in the Welcome screen. We'll select Java Enterprise from the left menu which allows us to take advantage of the enterprise framework support provid
Enjoy Spring Data JPA in IntelliJ IDEA 11
Spring JPA is a part of the Spring Data project that makes it easy to quickly implement JPA-based repositories. IntelliJ IDEA 11 recognizes repositories, provides quick navigation through the code, adds advanced completion, error highlighting and quick fixes. Download IntelliJ IDEA 11 Beta and try it.
JPA Console is Available in IntelliJ IDEA 10
In IntelliJ IDEA 10 a new JPA Console is added to existing Hibernate and Database consoles. Now you can run and test your JPA queries in a target environment of your application. Both Hibernate and JPA consoles are available if applicable. Note the new "Run Query in Console" Intention Action that is now available on all the supported types of queries: JPA QL, Hibernate QL and SQL. It allows you to quickly run a query directly from the editor in a corresponding console either new or already running.
Generate Persistence Mappings by Database Schema
The upcoming IntelliJ IDEA 8.1.1 includes a new option to generate separate XML mapping per entity.
Generating Persistence Mappings from Database Schema
With IntelliJ IDEA you can quickly generate persistence mappings from any database schema. This feature is not so easy to find, so here's the tip:
HQL Console with Pure JPA Facets
In IntelliJ IDEA HQL console can be used with pure JPA facets (as well as with Hibernate facets) to run JPAQL and HQL queries. All you need is Hibernate libraries and JDBC driver in a module classpath. If persistence.xml contains no Hibernate-specific database connection options, it should be mapped to an existing data source via JPA facet settings. Tip: HQL console can also be used to generate DDL statements for JPA and Hibernate mappings via its Generate DDL command. Update: If a Persistence Unit or Session Factory is mapped to a valid local Data Source there is no need to specify JDBC d
