Can someone help me understand how to use custom interceptors with the
convention plugin?
In my struts.xml I have:
<interceptor-stack name="defaultAuthenticationStack">
<interceptor-ref name="initialStack"/>
<interceptor-ref name="autoLoginStack"/>
<!-- now check for authentication -->
<interceptor-ref name="authenticationRequired"/>
<interceptor-ref name="endingStack"/>
</interceptor-stack>
Currently, we use a package via XML config and it works as expected:
<package name="account" namespace="/account" extends="default">
<default-interceptor-ref name="defaultAuthenticationStack"/>
</package>
But ideally we could use the convention plugin like this:
@InterceptorRef("defaultAuthenticationStack")
@Namespace("/account" )
public class UserAccount extends ActionSupport
{
....
}
When trying to init the framework I see my struts.xml file get loaded
but when the convention plugin tries to process the actions I get the
following error:

I noticed on the convention-plugin page that there is a reference to
using a default interceptor stack and a custom interceptor but not a
custom interceptor stack. I assumed you could use either.
@InterceptorRefs({
@InterceptorRef("interceptor-1"),
@InterceptorRef("defaultStack")
})
public class HelloWorld extends ActionSupport
{}
Ideas?
Thanks
