Web Services Addressing: firewalls and intermediary nodes
Using the Web Services Addressing (WS-Addressing) support in this product, we can create endpoint references that can be distributed across firewalls and intermediary nodes.
Using the WS-Addressing support, we 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 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. The client communicates with the HTTP server, which then routes the client requests to a specific server based on the HTTP server configuration.
