The following examples are provided to assist developers with their adoption and usage of EclipseLink's JAXB and native OXM functionality.
EclipseLink provides standards based JAXB implementation with many extensions. These references are for the JAXB 2.0 reference implementation which is included within EclipseLink for its XSD compiler capabilities (XJC).
EclipseLink MOXy Examples
- Getting Started
- No metadata is required to convert your existing object model to XML. Supply metadata (using annotations or XML) only when you need to fine tune the XML representation. Get started using MOXy.
- Using EclipseLink MOXy's JAXB
- Java Architecture for XML Binding (JSR 222) is the standard for XML Binding in Java. JAXB covers 100% of XML Schema concepts. Learn how to use MOXy as your JAXB provider.
- Meet in the Middle Mapping
- Normally in XML Binding solutions there is a one-to-one correspondence between the object model and the levels of nesting in the resulting XML document. Learn how to leverage MOXy’s XPath based mapping to remove these limitations.
- Using EclipseLink MOXy's XML Mapping (eclipselink-oxm.xml)
- Externalizing the JAXB and extended mappings in an eclispelink-oxm.xml mapping file can separate the XML bindings from the domain classes.
- Dynamic JAXB
- Traditional JAXB maps static classes (POJOs) to XML. Dynamic JAXB uses objects (instances of DynamicEntity) with generic get/set methods instead avoiding the need for the class generation step entirely.
- Mapping JPA Entities to XML
- JPA provides an easy and powerful means to use Java objects to interact with a relational database. These Java objects are called entities, and have their own characteristics. Some of these characteristics (bidirectional relationships, compound keys, embedded key classes, and lazy loading) can cause challenges when mapping these objects to XML. Learn how to easily map JPA entities to XML using MOXy.
- Converting POJOs to/from SDO DataObjects using the POJO/SDO Bridge (via JAXB)
- Using SDO or SCA and want to leverage JPA to access your persistent data? Learn how to expose your objects through SDO using MOXy.
