JAXB and java.util.Map

Is it ironic that it can be difficult to map the java.util.Map class in JAXB (JSR-222)?  In this post I will cover some items that will make it much easier.

Applying a Namespace During JAXB Unmarshal

For some an XML schema is a strict set of rules for how the XML document must be structured.  But for others it is a general guideline to indicate what the XML should look like.  This means that sometimes people want to accept input that doesn't conform to the XML schema for some reason.  In this example I will demonstrate how this can be done by leveraging a SAX XMLFilter.

JAXB and Namespace Prefixes

In a previous post I covered how to use namespace qualification with JAXB.  In this post I will cover how to control the prefixes that are used.  This is not covered in the JAXB (JSR-222) specification but I will demonstrate the extensions available in both the reference and EclipseLink MOXy implementations for handling this use case.

JAXB and JSON via Jettison - Namespace Example

In a previous post I described how Jettison can be leveraged by a JAXB implementation to produce/consume JSON.  A reader correctly pointed out that I did not describe how to handle namespaces.  Since JSON does not support namespaces you would not normally include them in your mappings.  However if you wanted to map your object model to both JSON and XML with namespaces, this post will demonstrate how it can be done.

JAXB & Namespaces

The majority of XML documents are namespace qualified, yet most XML binding examples do not demonstrate namespaces (sometimes because the XML binding solution does not support them). In this post I'll demonstrate how easy namespace handling is using JAXB.
