JQT is a query editor for Java that supports multiple ORM APIs (Java Persistence API, Hibernate Annotations, and more to come...) The project's main mission is to create an ORM implementation independent tool that can be used to browse entities and properties published by a session factory, edit and run queries in a user friendly editor, browse queries results, persist and remove objects using visual editors, and provide an extensible architecture to help developers add more functions. JQT parses entities located in its classpath, creating an entity metadata using a simple plug-in architecture to support multiple ORM APIs implementations. Current version has support to latest versions of plain Hibernate Annotations, Hibernate JPA Entity Manager, TopLink Essentials (JPA) and OpenJPA.
