7.6.6. Use a Client Side Interceptor in an Application

Summary

You can plug a client-side interceptor into an application programmatically or using a ServiceLoader mechanism. The following procedure describes the two methods.

Procedure 7.14. Plug the Interceptor into

    • Programmatically

      With this approach, you call the org.jboss.ejb.client.EJBClientContext.registerInterceptor(int order, EJBClientInterceptor interceptor) API and pass the order and the interceptor instance. The order is used to determine where exactly in the client interceptor chain this interceptor is placed.
    • ServiceLoader Mechanism

      With this approach, you create a META-INF/services/org.jboss.ejb.client.EJBClientInterceptor file and place or package it in the classpath of the client application. The rules for the file are dictated by the Java ServiceLoader Mechanism. This file is expected to contain a separate line for each fully qualified class name of the EJB client interceptor implementation. The EJB client interceptor classes must be available in the classpath. EJB client interceptors added using the ServiceLoader mechanism are added to the end of the client interceptor chain, in the order they are found in the classpath. The ejb-security-interceptors quickstart uses this approach.
