XML Schema to Java - Generating XmlAdapters

In previous posts I have demonstrated how powerful JAXB's XmlAdapter can be when starting from domain objects.  In this example I will demonstrate how to leverage an XmlAdapter when generating an object model from an XML schema.  This post was inspired by an answer I gave to a question on Stack Overflow (feel free to up vote).

JAXB and Enums

Today I answered a question on Stack Overflow (feel free to up vote) about JAXB and generating Java enums from an XML Schema.  This is normally straight forward, but there are a couple "gotchas" to be aware of.  In this post I'll demonstrate an easy and a harder use case.

JAXB and Java IO (Files, Streams, Readers, and Writers)

JAXB supports many different XML sources and targets.  In this post I'll give an overview of how JAXB can be used with those found in the java.io package: File, InputStream, OutputStream, Reader, Writer and their subclasses.

Binding to JSON & XML - Geocode Example

In a previous post I introduced the JSON binding that was added in the MOXy component in EclipseLink 2.4.  In that post I explained how the same metadata that is used for XML binding can be directly applied to JSON binding.  In this post I will demonstrate how powerful this is, by mapping one object model to both XML and JSON using the same set of metadata.  Google Maps Geocoding API V2 will be used to provide the XML and JSON inputs for this example.

Using an Unmarshaller.Listener to Capture the Location

Recently I came across a question on Stack Overflow asking how find where in the document an object was unmarshalled from. In this post I'll expand on my answer of using an XMLStreamReader and Unmarshaller.Listener to accomplish this.

JSON Binding with EclipseLink MOXy - Twitter Example

In a previous post I described how the Jettison library could be used with any JAXB implementation (Metro, MOXy, JaxMe, etc) to produce/consume JSON.  Now I'll demonstrate the native object-to-JSON binding MOXy JAXB introduced in EclipseLink 2.4.  With MOXy as your JAXB provider you can produce/consume JSON using the standard JAXB APIs (available in Java SE 6) without adding any compile time dependencies.
