Configuring web service binding custom endpoints to support a proxy server

You can configure SCA composites that are accessed by Hypertext Transfer Protocol (HTTP) for custom service endpoints using web services bindings.

Before you begin

Before you begin this task, install your Service Component Architecture (SCA) application.

About this task

When a service is exposed over the SCA web services binding, the service endpoint is specific to the server in which the service is hosted. Clients use this endpoint URI to access the service. In some cases, you may want clients to indirectly reference the service by using a proxy server as the service endpoint. For example, a proxy server is required to implement clustered web service binding endpoints. To enable clients to use a proxied endpoints, there are two ways to do this:
  • If your endpoints are specified in the SCA contributions composite definition or WSDL document location attribute, you must specify the proxy server endpoint instead of the WebSphere® server specific endpoint.
  • If your client resolves the endpoint by using the <reference target=””> attribute in your client composite definition, use the administrative console to configure the custom endpoints for SCA composites that are accessed by the Hypertext Transfer Protocol (HTTP) protocol. This approach is the most flexible for SCA clients within the same domain as their service providers. When using <reference target=””> attribute, SCA references can resolve the service endpoints without the client specifying endpoints in the composite definition or WSDL document.

Procedure

  1. In the administrative console, click Applications > Application Types > Business-level applications > application_name > composition_unit_name > Provide HTTP endpoint URL information .
  2. Select the HTTP endpoint URL prefix.

    When entering custom endpoints, specify one and only one endpoint URL prefix each for the HTTP and HTTPS protocols.

Results

You have configured web services bindings custom endpoints.

What to do next

You can configure the bindings to do transport layer authentication.
