EclipseLink
Comprehensive open-source Java persistence solution addressing relational, XML, and database web services.
Try it today
JPA
Provides standards based Object-Relational persistence solution with additional support for many advanced features.
EclipseLink JPA provides advanced support for leading relational databases and Java containers.
View details »
MOXy
Enables Java developers to efficiently bind Java classes to XML Schemas. MOXy implements JAXB allowing developers to provide
their mapping information through annotations as well as providing support for storing the mappings in XML format.
The many advanced mappings enable developers to handle the complex XML structures without having to mirror the schema in their Java class model.

DBWS
Declarative Web Service solution for accessing relational databases. The DBWS Builder generates the
necessary configuration files based on the provided database artifacts so that EclipseLink's relational and persistence services
can be combined to handle the requests.
