JBOSS - Hibernate Tools

JBoss Tools eClipse plugin is very powerfull tool to manage your hibernate objects and queries.

Hibernate Tools provides easy generation, testing and prototyping of your Hibernate or JPA mapped projects. Use it to Run queries, browse mappings and generate code for your data projects.

Hibernate Code Generation Launch

Generate artifacts based on Hibernate model

Hibernate Tools provide a code generation launch configuration which can take the configured Hibernate model and use for various code generation tasks.

Since it is a launch configuration it is easy to run it repeatedly while developing via the Launch Configuration menu.

Hibernate Console

Browse your model & database

HQL Editor

Prototype your queries In the HQL editor you can prototype your HQL queries and see the result in the Hibernate Query Result viewer.
