TopLink Essentials, like JBoss's Hibernate product, is an open source object-relational persistence framework or layer used in Java applications. While both products strive to deliver a non-intrusive highly flexible and performant solution there are some key differences. TopLink Essentials, derived from Oracle TopLink has been in production Java applications scaling to large deployments and high transaction volumes for over a decade.

TopLink Essentials is the open-source community edition of Oracle's TopLink product. It is derived from Oracle TopLink providing core Object-Relational Mapping (ORM) functionality necessary for the reference implementation of JPA in EJB 3.0. TopLink Essentials is available in source and binary distributions as the entity-persistence module of GlassFish Open Source Java EE 5 Application Server or can be separately downloded from here.

TopLink Essentials is a subset of the functionality available in Oracle TopLink. The initial goal of TopLink Essentials is to provide a commercial quality reference implementation of JPA. They share the same core Object-Relational Mapping capabilities that have been key infrastructure of many enterprise Java application for over a decade. Oracle TopLink offers additional functionality beyond TopLink Essentials and the JPA specification. See similar questions...

TopLink Essentials is freely licensed and distributed under CDDL. "The OSI-approved CDDL license is being used for project GlassFish which allows developers to view, use, edit, and alter the code, and distribute it or use it in production." For more information on the CDDL licensing using in GlassFish please refer to the GlassFish FAQ as well you can find more details here. See similar questions...

Within GlassFish there is a persistence mailing list persistence@glassfish.dev.java.net. The archives of this mailing list are available here. See similar questions...

TopLink Essentials supports any JDBC and SQL compliant database. It ships with several data platform configurations that can be selected to allow native or non-standard SQL operations to be generated. As part of ongoing testing and certification efforts TopLink Essentials is also tested against many of the leading databases. The JPA specification defines the core object-relational capabilities most applications require. See similar questions...

Yes, TopLink Essentials through the pluggable persistence capabilities will function as the persistence provider in an compliant EJB 3.0 container. See similar questions...

There is no mapping tool support directly within TopLink Essentials or GlassFish. Developers can use any development environment that supports JDK 1.5 or higher allowing the use of annotations and some of the new features leveraged in the API. There are currently efforts going on in most leading IDE's to deliver better support for using JPA. Oracle is leading the way with the early support for JPA in JDeveloper 10.1.

Yes, TopLink Essentials offers support for deployment within an EJB 3.0 container or outside the container. This includes using the persistence API in Web Containers, other non-EJB 3.0 Java EE containers, or in Java SE. This allows the persistence API to be used anywhere Java is used.

JPA is a specification for persistence in Java EE and SE applications. As with all specifications they still require vendors or open source projects to implement them. TopLink Essentials is the first compliant JPA implementation providing the persistence functionality to the EJB 3.0 reference implementation. Oracle TopLink is Oracle's commercial implementationcurrently providing preview functionality of JPA. See similar questions...

Yes, but you should watch the cost of fittings and plastic must be supported every two feet. Do not substitute fittings with Radiantec tubing. If you are using an open system, be sure that the materials are rated potable. All Radiantec polyethylene tubing is highly resistant to nearly everything. The reactivity charts show only a slight reaction to fuming nitric acid (above 1700° F) See similar questions...

Technically it's not hibernation, but they will slow down their body functions (they become "torpid") if the room temperature of the room they are in gets unusually low, but shouldn't just go into hibernation just because it's the winter season. If your hamster reaches this state, in most cases do not to disturb them. Let them come out of it naturally. Golden hamsters become sluggish at about 14C and torpid at about 10C.
