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.
