EclipseLink Filters How-To

I have been assisting customers with their comparison of JPA/Object-relational frameworks as well as assisting them with migrating to EclipseLink JPA. One issue I ran into recently involves migrating users of Hibernate who use Filters over to EclipseLink. A filter is basically an additional set of criteria with session specific (more...)

Using partial EclipseLink JPA entities with JAXB

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 (more...)

EclipseLink Summit 2010 Wrap Up


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 (more...)

EclipseLink Summit 2010

In an effort to increase the community of committers and contributors with in-depth knowledge of EclipseLink we have decided to host a 3-day Summit. The goal of this Summit will be to exchange detailed technical information and discuss future direction for the project and its persistence services.

All interested parties are welcome to participate.

More info on Summit is available here.

EclipseLink on LinkedIn

I was back in the field last week helping a customer with their migration to EclipseLink from a 3rd party developed solution using TopLink Essentials. Generally these migrations are very straight forward but in this case we bumped into a few unique wrinkles caused by the original solution being developed (more...)

EclipseLink 1.0 Released

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:
