I have never tried to use this with Mule but if someone has, please let me know so I can update this post.

I have uploaded the Java code for the BasicAuthAuthorizationInterceptor class. There are a few changes over the original version. This one includes a Map of authorized users and their corresponding passwords. I believe the original example I created was for Apache CXF 2.0. This version works with Apache CXF 2.1.1.

In the original post, I also did not include a sample of how to use this code in a real application. The following section shows a sample of how to define the security interceptor and enable it on a simple endpoint.

      <property name="users">
        <map>
          <entry key="username" value="password"/>
        </map>
      </property>
    </bean>

    <bean id="service" class="sample.Service"/>

    <jaxws:endpoint
      id="serviceEndpoint"
      implementor="#service"
