Type mappings associate a Java class and a corresponding XML type by dedicated Serializer 

and Deserializer implementations. This is a very powerful, yet extensible pattern and you 

see that even SUN can learn from flaws they built into their native serialization API. 

JAXR is the upcoming API to interface XML registries, such as UDDI, from Java. It is the 

youngest of the presented API s and yet rarely supported. 

What is Axis?  

Axis is an Open Source implementation of the JAX RPC API from Apache. It realizes the 

basic concepts of handlers and type mappings driven by a lightweight SAX based processing 

engine. Axis comes with a dedicated deployment format called Web Service Deployment 

Descriptor (WSDD) which configures the runtime engine with new request/response flows 

(these are named chains of handlers that together perform a reasonable preprocessing), 

service providers (these are special handlers that construct the end points of processing 

chains and that perform the actual logic of a Web Service call), and type mappings. Axis 

comes with a ready made http transport listener in the form of a Servlet that can be 

installed in any compliant web container.

Configuring JBoss.Net 

What is JBoss.Net 

JBoss.Net is an integration module that fits the Axis JAX RPC package optimally into the 

hot deployment environment of JBoss:  

JBoss.Net provides a new archive format called Web Service aRchive (WSR) which 

bundles serialization code, web service logic and WSDD descriptors.  

JBoss.Net comes with a set of suitable providers which interface the proper container 

managed JMX & J2EE  logic.  

JBoss.Net has the ability to bind JAX RPC enabled service stubs to external Web 

Services into the JNDI tree and hence make them visible to all parts of the container 

and your application. Usually, such stubs have been generated from WSDL 

descriptions.   

JBoss.Net has the ability to automatically publish your Web Services to global UDDI 

registries. JBoss.Net will have a non production use UDDI server implementation for 

test purposes.
