19 JAX-RPC 1.1 specification 167 pages

20 JAX-RPC 1.1 an API for building –web services –web service clients JAX-RPC is dependent upon SAAJ # - Remote Procedure Call

21 JAX-RPC packages javax.xml.rpc javax.xml.rpc.encoding javax.xml.rpc.handler javax.xml.rpc.handler.soap javax.xml.rpc.server javax.xml.rpc.soap

22 SAAJ versus JAX-RPC “Most developers will not use the SAAJ API, but will use the higher-level JAX-RPC API instead.” (Sun, J2EE 1.4 Tutorial)

23 JAXR 1.0 specification 119 pages

24 JAXR 1.0 standard API for accessing XML registries supports UDDI and ebXML registries
