JAXP: Java API for xml processing. It PROVIDES the validation capability and parsing XML documents. There are three BASIC parsing interfaces in JAXP are DOM, SAX and Straming API for XML STAX.

JAXB: Java Architecture for XML Binding: The java classes are mapped to XML representations. The two main features of JAXB are the ability to marshal Java objects into XML and UNMARSHAL XML back to Java objects.

The Java API for XML Messaging (JAXM) enables distributed software applications to communicate using XML (and SOAP). JAXM supports both asynchronous and synchronous messaging.

JAX-RPC: Java API for XML based RPC. Allows a java based web service that is to be invoked by a Java application provided the description, still being consistent with WSDL description. This can resemble as Java RMI over web SERVICES.

Allowing a web service to be implemented at server side as a servlet/jsp or EJB container is the advantage of JAX-RPC.
