Release 5.0.0.20

Date: Apr 7, 2013

Juno 5.0.0.20 is a major update.

Core API changes​

  • New Jena-based RdfSerializer for serializing POJOs to RDF/XML, RDF/XML-ABBREV, N-Triple, Turtle, and N3. Serializes ANY POJOs to RDF, even simple objects and primitives.

  • New Jena-based RdfParser for parsing RDF/XML, RDF/XML-ABBREV, N3, Turtle, and N-Triple back into POJOs.

  • XmlSerializerContext.XML_autoDetectNamespaces default changed to true. The old default value would cause XML with unmapped namespaces if you didn't manually specify them via the XmlSerializerContext.XML_namespaces annotation. While setting the default to true is somewhat slower (since the serializer must crawl the POJO tree to find namespaces), the benefits of having it work out-of-the-box outweighs the performance concerns. For developers concerned about performance, they can always change it back to false and specify the namespaces themselves.

REST server API changes​

  • Allow inheritance of @RestResource annotation. Serializers, parsers, filters, properties , guards, and converters definitions are automatically inherited from parent classes and interfaces.

  • Enhancements to @RestMethod annotation:

    • New RestMethod.filters() annotation for defining POJO filters at the method level.
    • New RestMethod.serializersInherit() and RestMethod.parsersInherit() annotations for controlling how serializers and parsers (and associated filters and properties) are inherited from the class. This replaces the previous addSerializers and addParsers annotations.

  • New RestServletJenaDefault servlet that includes serialization/parsing support for all Jena-based serializers and parsers.

  • New DefaultJenaProvider JAX-RS provider that includes serialization/parsing support for all Jena-based serializers and parsers.

  • Eliminated RestServletChild class. It's redundant with the introduction of inheritable annotations.

  • New methods on RestServlet:

    • RestServlet.createConfigFactory()
    • RestServlet.createSerializers()
    • RestServlet.createParsers()

    These augment the existing getBeanContext() / getSerializers() / getParsers() methods.

REST client API changes​

  • New RestCall.setDateHeader(String,Object) method for setting ISO8601 datetime headers.
