Using the Web Services Addressing (WS-Addressing) support
in this product, you can create endpoint references that can be distributed
across firewalls and intermediary nodes.
Using the WS-Addressing support, you can automatically generate
endpoint references that represent endpoints on the node on which
the references are generated. These endpoint references contain appropriate
address information, based on the URL configured for the endpoint
and any valid proxy configuration for the server that hosts the endpoint.
Messages targeted at the endpoint reference from the client are routed
to the endpoint through the appropriate intermediary node or nodes,
as described in the following topology scenarios.
Direct connection
In this topology, there is no intermediary node.
The client communicates directly with the server that hosts the target
endpoint. In this topology, the WS-Addressing APIs automatically generate
the appropriate endpoint reference address, based on the URL configured
for the Web service module. This scenario is illustrated in the following
diagram.
Endpoint
references created by using the standard JAX-WS API are not workload
managed.
HTTP server, such as IBM HTTP
Server
In this topology, the
IBM WS-Addressing API automatically generates the appropriate endpoint
reference address based on the URL prefix of the HTTP server that
is configured for the target Web service module.
You must provide
HTTP endpoint URL information, that is, configure the HTTP URL prefix
for each deployment of each application. The client communicates with
the HTTP server, which then routes the client requests to a specific
server based on the HTTP server configuration.
