EclipseLink 2.4.0 Released

I am very excited to announce that EclipseLink 2.4.0 is now available for download.

Highlights of this release include:....

RESTFul Persistence

Java Persistence units can now be exposed over REST using either JSON or XML media.

Tenant Isolation - Table per tenant

Developers can design and deploy applications where their persistent entities are stored in separate tables per tenant.

NoSQL

This release introduces EclipseLink's NoSQL support for MongoDB and Oracle NoSQL.

JSON

EclipseLink MOXy can now be used for the marshaling and unmarshaling of JSON object. This is core infrastructure to the JPA-RS feature.

... and much, much more...

Please see this link for a complete feature list and to download 2.4.0 to try it yourself!!

EclipseLink: Multitenancy with Oracle VPD

2011-08-24T08:14:06.330-07:00

As of EclipseLink Indigo (2.3.0) you have been able to use the @Multitenant feature to share a database schema between multiple tenants. Did you know that you can also use this feature together with the Oracle Virtual Private Database (VPD) support that has been available in EclipseLink since version 1.0?

This powerful combination of features allows for the shared tables to be managed directly on the database, and for inserts to be automatically associated with the proper client. Any SQL executed by EclipseLink (even if EclipseLink did not generate it - ie native queries) will go through VPD and return only the client specific rows.

Since VPD can be configured per table, applications can be configured to use VPD on some tables, and share others.

A running example, complete with source code is available on the EclipseLink wiki.





GlassFish 3.1.1 Ships with EclipseLink 2.3!

2011-07-28T11:34:01.906-07:00

GlassFish 3.1.1 shipped today which makes it the first application server with the new multi-tenancy and extensible persistence unit support as well as all the other new features included in EclipseLink 2.3. If you're a GlassFish developer and you're upgrading to 3.1.1 you can find out all about the new features available in EclipseLink 2.3 on the EclipseLink Wiki.

To wet your appetite, Alexis Moussine-Pouchkine posted a screencast of building a multi-tenant enabled application on a pre-release build of GlassFish 3.1.1 on his blog and now would be a great time to check it out!

EclipseLink 2.3.0 (Indigo) Released

2011-06-22T11:05:22.669-07:00

Since joining the family here at Eclipse a few years ago, one thing I can always count on is a hectic and exciting start to summer. This summer is no exception, and is kicked off with the release of EclipseLink 2.3.0 (Indigo).

Before I continue with brief descriptions of some of the new features of EclipseLink 2.3.0, I would like to thank everyone who was involved with this release. Whether your contribution to the project consisted of finding and entering bugs, contributing to the forums, or designing and implementing features, your contribution was important to the success of this project. Thank you, and I look forward to your contributions to our next major releases.

There are too many features and enhancement requests to touch on everything in this blog post, so I am going to limit it to what I believe are the highlights. For a complete 2.3.0 feature list, and to download and try out some of this stuff yourself, please click here.

Extend Entities
2.3.0 offers EclipseLink users the ability to extend their model (JPA entities or MOXy JAXB beans) so that a set of additional extended mappings can be used at runtime. These additional mappings offer more flexibility for developers that may not know all the mappings required for the application at design time.

Support Multiple Tenants
2.3.0 offers developers the ability to design and deploy applications where their persistent entities for multiple tenants are stored in a shared table. A column (or columns) in the table is designated as the discriminator for the tenant.

Externalize Mappings
Mappings for your model (JPA entities or MOXy JAXB beans) can now be stored externally to the running application. This allows mapping overrides and extended mappings (new in 2.3.0) to be easily and dynamically integrated into deployed applications.

Multiple Database
Developers can now store different entities in different databases, and even have relationships between them using Composite Persistence Units (PU). This feature gives developers the ability to build persistence units, each connecting to their own datasource, and compose them together under a parent PU. The parent PU is then used as if it is a standard persistence unit.

Click here for more information, including examples and docs, on the above features, and to download 2.3.0.

EclipseLink Indigo Preview: Shared Databases for Multiple Tenants

2011-06-17T12:42:35.876-07:00

Challenged to take an existing application and re-use it for a new customer or group of users (tenant)? Instead of customizing the application, adding new hardware or re-configuring the database for each new tenant, you can now build EclipseLink JPA enabled applications hosting requests from multiple tenants with all their data co-located.

Starting with EclipseLink 2.3, part of the annual Eclipse Indigo release, you can now have multiple application tenants sharing a database schema. EclipseLink enables you to configure your database tables for shared storage by simply providing tenant discriminator column(s) and providing values for these discriminators within your application. This allows your tenants to share the same schema without being aware of one another.

Of course in some instances, you may wish to share some data across tenants. No problem! EclipseLink allows you to share and isolate as much or as little as your application requires.

The beauty and ease of creating such an environment lies simply in decorating those entities that need to be isolated per tenants with an @Multitenant specification. Shared entities need not be configured any further then required by the JPA specification.

For more information on how to take advantage of this new functionality, follow the link:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/Multitenant

Please note: The final release date for EclipseLink 2.3 is June 22, 2011 and the examples and documentation will evolve as the release date approaches. If you would like more detail, please check back after the release date or take advantage of our mailing lists and forums.



Extend your Persistence Unit on the fly

2011-06-10T14:12:28.347-07:00

Imagine a system that keeps track of player statistics in a sports league. Personal information such as name, height, weight and basic statistics such as the number of games played is stored for all players.

A persistence unit is deployed with all the mappings described above.

The system admin of a basketball league wants to use the system and add mappings for points scored and fouls. As the system is running they tell EcliseLink about mappings for those fields and the next EntityManager they get uses them.

Starting with EclipseLink 2.3, you can do just that. To do that, all you have to do is:

- Build a traditional persistence unit
- Tweak your Entities so they can hold added mappings
- Build room for additional data into your database schema
- Define a repository to contain your additional mappings and tell EclipseLink about it

With those steps, any EntityManager created from your persistence unit will use your new mappings.

Additionally, you can refresh your EntityManagerFactory. Any EntityManager created after the refresh will use any new mappings added to the repository since the previous refresh.

The following link shows an example of how a system as described above could be configured. Please note: The final release date for EclipseLink 2.3 is June 22, 2011 and the examples and documentation will evolve as we get closer to that date. If you would like more detail, please check back after the release date or take advantage of our mailing lists and forums.

Using partial EclipseLink JPA entities with JAXB

2010-08-05T07:46:53.306-07:00

I spent much of the final months of the EclipseLink 2.1 (Helios) development championing the enhancements of our existing FetchGroup support to address additional uses cases around working with partial entities. The new functionality is referred to as AttributeGroup with support for FETCH (what columns get retrieved from the database), LOAD (what relationships are populated), COPY (what attributes and relationships and populated in detached copy), and MERGE (what attributes are merged from a detached partial entity). This additional support greatly simplifies application development where detached entities are used as well as providing additional performance tuning options and flexibility for other scenarios.The purpose of this blog post is to help a user we were assisting on Twitter who wanted to use JAXB to marshal JPA entities into XML but only wanted a portion of the entities to be used. By default JAXB will traverse all available relationships including lazy ones that have not been loaded to build a complete XML document for the provided entities.Here is a simple example reading a Customer with an Address (1:1) and PhoneNumber(s) (1:M) from a database and marshalling it into XML using EclipseLink JPA with EclipseLink MOXy.Setup code for JPA and JAXB: // JPA EntityManagerFactory emf = Persistence.createEntityManagerFactory("CustomerService");EntityManager em = emf.createEntityManager();// JAXBJAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); Example: Find & Marshall CustomerCustomer customer = em.find(Customer.class, 1);marshaller.marshal(customer, System.out); When executed this generates the following XML and causes the customer's address and phone numbers to be loaded from the database.Now, if we wanted to generate a partial XML document including only the Customer's basic attributes and its address's attributes we could use a copy group to create a partial copy and marshal it: Customer customer = em.find(Customer.class, (long) 1);CopyGroup cg = new CopyGroup();cg.addAttribute("id");cg.addAttribute("firstName");cg.addAttribute("lastName");cg.addAttribute("address.id");cg.addAttribute("address.city");cg.addAttribute("address.street");JpaEntityManger nativeEM = em.unwrap(JpaEntityManager.class);Customer custCopy = (Customer) nativeEM .copy(customer, cg);marshaller.marshal(custCopy , System.out); Now the generated XML appears as:There are other combined uses of AttributeGroup that can be used to control what is fetched and loaded as well but this copy example should illustrate some of the options available and how EclipseLink JPA and MOXy components can be easily used together.DougAdditional MOXy examples available here.[...]

EclipseLink Summit 2010 Wrap Up

2010-06-01T11:06:55.147-07:00

(image)
Last week we held our first EclipseLink Summit here in Ottawa with attendees from Canada, Germany, India, and the US. The principal goal of the summit was the exchange of technical information and ideas. We believe the event was a tremendous success!

We spent 2 days with committers leading technical sessions discussing areas from high level components and architecture to the detailed workings of EclipseLink's querying, caching, transactions, management, diagnostics, metadata processing, JPA 2.0 metamodel, and several other subsystems.

We would like to extend a big thank you to all of the committers who lead those sessions. The preparation time invested was obvious and the quality was amazing. We know it was tough to squeeze this additional work into your hectic pre-Helios schedules. The feedback from all attendees was excellent.

On the 3rd day of the Summit we focused more on the project itself. Starting with a talk from Jeff McAffer (EclipseSource) on OSGi and Eclipse RT technologies. We then discussed EclipseLink and OSGi, documentation, development process, build, testing and our road map planning.

While not all of these sessions allowed us to come to concrete conclusions the discussions were great and will hopefully carry on in our weekly committer meetings where we continue to improve our processes and refine our direction.

For those interested a more detailed summary of our Thursday sessions will be published to the eclipselink-dev@eclipse.org mailing list and topics requiring further discussion will be added to the weekly meeting agenda.

Thanks again to all the presenters and attendees. We are all looking forward to future EclipseLInk Summits where we can gather committers, contributors, and and users to share ideas and grow our community.

Your Summit Program Committee

Doug Clarke, Peter Krogh, and Shaun Smith

SDO 2.1.1 (JSR-235) Releases with EclipseLink as the Reference Implementation

2009-05-12T09:09:36.937-07:00

I am happy to announce that SDO 2.1.1 (JSR-235) has been approved by the JCP, and EclipseLink SDO is the reference implementation.


EclipseLink Download
http://www.eclipse.org/eclipselink/downloads/


Reference Implementation Download
http://www.eclipse.org/eclipselink/downloads/ri.php


SDO is a generic structure to represent data from many sources such as XML and relational databases, most commonly associated with SCA.
http://wiki.eclipse.org/EclipseLink/FAQ/WhatIsSDO


EclipseLink SDO was implemented as a thin layer on top of EclipseLink's object-to-XML layer (which is also the base for EclipseLink JAXB). EclipseLink SDO can be used alone, or as a means to expose POJOs as DataObjects so that components like EclipseLink JPA and JAXB can be used.

EclipseLink 1.0 Released

2008-07-09T12:34:57.201-07:00

The Eclipse Persistence Services project (EclipseLink) has completed its incubation phase and the 1.0 release is available for download. This release completes the transition of the persistence functionality developed in Oracle TopLink to being fully developed and maintained as an open source project at Eclipse. This also signifies the first release of a project under the recently created top-level Runtime (RT) project at Eclipse.EclipseLink delivers persistence services for efficiently working with Java and relational, XML, and non-relational data sources. The highlights include:· Compact: Standard Java distribution is composed of a single implementation jar and utility jars that can be used in any Java SE, IDE, or Java EE hosted environment.· OSGi: EclipseLink is also available as a set of OSGi bundles. This distribution offers out of the box support for compliant OSGi implementations, as well as Equinox-specific extensions.· JPA: Superior Java Persistence API 1.0 implementation with many advanced features offering greater flexibility and performance for mapping, caching, querying and transaction processing.· MOXy: Object-XML binding support with JAXB, offering highly flexible mappings as well as a meet in the middle configuration approach.· SDO: Service Data Objects 2.1 implementation enabling flexible service integration with dynamic and static models.· Utils: Migration utilities to assist developers currently using Oracle TopLink or TopLink Essentials in their upgrade to EclipseLink as well as the workbench for compatibility with classic object-relational and object-XML mapping.A complete index of features and the full user documentation for EclipseLink is available on the Eclipse wiki.Standards FocusedThe mandate of the EclipseLink project is to deliver a set of persistence services that leverage the leading Java standards. In addition, advanced features were added based on user requests but implemented in a way that allows developers to leverage them when needed but not be obstructed by them when they are not needed.This is particularly true in JPA, where many advanced features are available through JPA persistence unit properties and query hints, in addition to custom annotations and XML. With EclipseLink replacing TopLink Essentials as the reference implementation for JPA 2.0, some of these advanced features will evolve into the specification defined metadata and interfaces. This approach of leading through delivery of advanced functionality, and then contributing back to the standards, is an important aspect of the EclipseLink project.Growing The CommunityThe EclipseLink committers understand very well that developing in open source is much more than just providing access to the source code. Building a successful open source project is really about building an active community based on open communication and a transparent development process. We encourage the Java community to try out the 1.0 EclipseLink release and provide feedback. Your contributions and suggestions are valuable to us and will help ensure the project meets your current and future needs.EclipseLink is currently available directly from the EclipseLink project web site and is also included within the GlassFish and Spring Framework distributions. Going forward, the Oracle TopLink product releases within the Oracle WebLogic Server will also include EclipseLink as its strategic persistence provider.At present the project has committers from Oracle and Sun but we also have a growing community of users and d[...]

Welcome to our new committer, Mitesh Meswani

2008-04-04T08:17:14.965-07:00

I want to welcome Mitesh Meswani of Sun Microsystems who has just joined the EclipseLink project as a committer.

Mitesh has been working with us on the EclispeLink code base since the beginnings of the Java Persistence API. Most recently, he has been helping us get our distribution to a state where it is easier for people using maven to consume. In the past he wrote our Derby/JavaDB support, added code to allow us to automically detect what database is being used, and provided a number of complex bug fixes.

Welcome Mitesh, we are excited to have you on board, and looking forward to more great contributions!
