Mapping Objects to Multiple XML Schemas - Weather Example

I have written previous posts on EclipseLink JAXB (MOXy)'s @XmlPath and external binding file extensions.  In this post I will demonstrate how powerful these extensions are by mapping a single object model to two different XML schemas.  To make the example more "real", the XML data will come from two different services that provide weather information:  Google and Yahoo.

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.

Map to Element based on an Attribute Value with EclipseLink JAXB (MOXy)

I am happy to announce that we are expanding MOXy's XPath based mapping in EclipseLink 2.3. You are now able to map to an element based on the value of an attribute.  This is done by leveraging XPath predicates via MOXy's @XmlPath annotation. 

You can try this out today by downloading one EclipseLink 2.3.0 nightly downloads starting on March 22, 2011 from:

XPath Based Mapping - Geocode Example

In a previous post I introduced MOXy's XPath based mapping JAXB extension.  In this post I'll use Google Maps Geocoding API V2 to demonstrate how powerful this extension is.

XPath Based Mapping

In this post we'll explore the XPath based mapping aspect of EclipseLink JAXB (MOXy).  XPath based mapping is what allows an existing object model to be mapped to an existing XML schema.  MOXy is the only XML binding solution I'm aware of with this ability and therefore the only true object-to-XML mapper (OXM).
