Extending the interceptor: While not very common for users to extend, this interceptor is extended by the Example code: <action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="token"/>
<interceptor-ref name="basicStack"/>
<result name="success">good_result.ftl</result>
</action>
<-- In this case, myMethod of the action class will not
get checked for invalidity of token -->
<action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="token">
<param name="excludeMethods">myMethod</param>
</interceptor-ref name="token"/>
<interceptor-ref name="basicStack"/>
<result name="success">good_result.ftl</result>
</action>
