Explain JAXR Architecture

Main components of JAXR

Registry Provider

• Provides an implementation of a registry specification
• is not expected to implement JAXR specification
• examples: UDDI registry, ebXML registry

JAXR Provider

• Implements JAXR specification
• Typically functions as facade to existing registry providers
• example: JAXR reference implementation

JAXR Client

• Uses JAXR APIs to access services provided by JAXR Provider

Remote communication occurs between JAXR provider and Registry providers.

JAXR client and JAXR provider are expected to be co-located in a same JVM in most implementations.

JAX-R provider implementation

JAX-R provider implementation can be composed of :

1. JAXR pluggable provider

• Provides a single abstraction for multiple registry-specific JAXR providers.
• Provides a Pluggable ConnectionFactory implementation that can create JAXR Connections using the appropriate registry-specific JAXR provider.

2. Registry-specific JAXR provider

• Plugs into JAXR pluggable provider.
• Translates client request to registry provider specific request and dispatch them using registry provider specific protocol.
