A web service application, such as a JAX-WS or JAX-RS application, can be configured to use a policy set which will attach the policies in the policy set to the application. If you are unfamilar with policy sets, check our our policy sets article.
Expand Applications > Application Types, and select WebSphere enterprise applications. In the Web Services Properties section, select Service client policy sets and bindings. If the Service client policy sets and bindings option is not displayed, this suggests that the application is not a JAX-WS or JAX-RS application.
In Service client policy sets and binding, select Attach Client Policy Set, and select a policy set.
