Content:Object Relational Mapping, Persistence and Caching for JavaApache Cayenne is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services. With a wealth of unique and powerful features, Cayenne can address a wide range of persistence needs. Cayenne seamlessly binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. Or, with native XML serialization, objects can be even further persisted to non-Java clients - such as an Ajax-capable browser. Cayenne is designed to be easy to use, without sacrificing flexibility or design. To that end, Cayenne supports database reverse engineering and generation, as well as a Velocity-based class generation engine. All of these functions can be controlled directly through the CayenneModeler, a fully functional GUI tool. No cryptic XML or annotation based configuration is required! An entire database schema can be mapped directly to Java objects within minutes, all from the comfort of the GUI-based CayenneModeler. Cayenne supports numerous other features, including caching, a complete object query syntax, relationship pre-fetching, on-demand object and relationship faulting, object inheritance, database auto-detection, and generic persisted objects. Most importantly, Cayenne can scale up or down to virtually any project size. With a mature, 100% open source framework, an energetic user community, and a track record of solid performance in high-volume environments, Cayenne is an exceptional choice for persistence services. Cayenne team is in the process of building a spec-compliant open source JPA Provider. NewsCayenne team is glad to announce a second milestone of Cayenne 3.0. It contains many new features, such as full EJBQL syntax (delete, update, select, aggregate queries, subqueries, etc.), much improved lifecycle callbacks (no need to wrap the DataContext or enable callbacks explicitly. Modeler callbacks support is coming in M3), to-many relationships mapped as sets and maps (with Modeler support), CayenneModeler search function, adapter for SQLite, and much more....

Cayenne team is glad to announce a new release of Cayenne 2.0 and 1.2. Both 2.0 and 1.2 are Cayenne stable branches so there are no new features. Still the release includes a number of important bug fixes. So it is a recommended upgrade for the current users. As always there is a patch-level compatibility between 1.2.4 and 2.0.4....

Apache Cayenne team is glad to announce the first milestone release of Cayenne 3.0. The milestone status means that the release is under active development, and some of the new features do not yet have all expected bells and whistles, still the existing core is stable and has been deployed in production by a number of users already. If you look at the list of new features, it has quite a few things....

Cayenne team is glad to announce a new release of Cayenne 2.0 and 1.2 branches. The new release features a long list of bug fixes and is a recommended upgrade for the current users. As always there is a patch-level compatibility between 1.2.3 and 2.0.3.... Cayenne Modeler
Persistent Java classes are generated and synchronized with the mapping using the Modeler or alternatively with an Ant task. A database SQL schema can be generated from the Modeler and also with simple API calls. |
