EclipseLink MOXy and the Java API for JSON Processing - Object Model APIs

The Java API for JSON Processing (JSR-353) is the Java standard for producing and consuming JSON which was introduced as part of Java EE 7.  JSR-353 includes object (DOM like) and stream (StAX like) APIs.  In this post I will demonstrate the initial JSR-353 support we have added to MOXy's JSON binding in EclipseLink 2.6.  You can now use MOXy to marshal to:

• javax.json.JsonArrayBuilder
• javax.json.JsonObjectBuilder

 And unmarshal from:

• javax.json.JsonStructure
• javax.json.JsonObject
• javax.json.JsonArray

You can try this out today using a nightly build of EclipseLink 2.6.0:

The JSR-353 reference implementation is available here:

Mapping Bad XML - Enumerated Collection Elements

In a previous post I introduced EclipseLink JAXB (MOXy)'s @XmlVariableNode extension.  In this post I'll demonstrate how @XmlVariableNode could be leveraged to handle an interesting question I came across on Stack Overflow.  In that question instead of a collection being represented with an element that appeared multiple times, the element name contained the index.  While I would never recommend structuring your XML document this way sometimes you encounter it and need to be able to map it.

MOXy's @XmlVariableNode - Using a Map's Key as the Node Name

People often ask me how they can map a java.util.Map such that the keys become the node names.  In this post I will demonstrate how this can be done using the new Variable Node mapping that we have added in EclipseLink MOXy.

MOXy's @XmlVariableNode - JSON Schema Example

We are in the process of adding the ability to generate a JSON Schema from your domain model to EclipseLink MOXy.  To accomplish this we have created a new Variable Node mapping. In this post I will demonstrate the new mapping by mapping a Java model to a JSON Schema.
