Deploying and Packaging a Service Endpoint

point. This link element associates the Web service port to the actual endpoint

implementation defined in either the 

web.xml

 or 

ejb jar.xml

 file.

The JAX RPC mapping file, which is specified using the 

jaxrpc mapping 

file

 element in 

webservices.xml

, keeps details on the relationships and map 

pings between WSDL definitions and corresponding Java interfaces and defini 

tions. The information contained in this file, along with information in the WSDL,

is used to create stubs and ties for deployed services.

Thus, the Web services deployment descriptor, 

webservices.xml

, links the

WSDL port information to a unique port component and from there to the actual

implementation classes and Java to WSDL mappings. Code Example 3.23 is an

example of the Web services deployment descriptor for our sample weather Web

service, which uses a JAX RPC service endpoint.
