Control Interceptor order

[Richard Sayre <ri...@gmail.com>]

I added an Interceptor locally to one of my Actions.  This Interceptor
implements SessionAware and has a setSession(Map session) method to
get the session.  The problem is when my interceptor runs session is
null.  I am assuming this is because the interceptor that populates
the session aware objects is not running before this one.  How can I
insure that my interceptor runs after the interceptor that sets the
session?
My package extends struts-default so I know that the SessionAware
interceptor should be running.  I want my Interceptor to run after the
struts-default interceptors are finished.

Here is my XML

<interceptors>
            <interceptor name="accessChecker"
class="interceptors.design.GlobalDesignAccessInterceptor"/>
</interceptors>

<global-results>
       <result name="noAccess" type="redirect-action">
         <param name="actionName">Home</param>
         <param name="namespace">/</param>
       </result>
</global-results>

<action name="selectCustomer" class="actions.design.Customer"
method="populateCustomerList">
            <interceptor-ref name="accessChecker"/>
            <result name="success">/GlobalDesign/selectCustomer.jsp</result>

</action>

I can get it to work if I get the session by using
ActionContext.getContext().getSession(); but the FAQ Question
referenced from this page
http://struts.apache.org/2.x/docs/interceptors.html called "How do we
get access to the session?" says the preferred method is to implement
SessionAware.

Thank you,

Rich

Others should definitely correct me if I'm wrong, but interceptors don't
inject other interceptors, just actions.  If you need access to the Session,
just use the one in the ActionInvocation.
