Thank you! That makes perfect sense now.

Hi Ryan
In Convention, as well as in XML, if you try to use an interceptor or
result outside the package where it is defined, you will get an error.
You interceptor is defined in your package, and your actions are
getting mapped in Convention into another package. To fix this you
need to either: make convention put your actions in the package where
the interceptor stack is defined (using @ParentPackage, or setting
"struts.convention.default.parent.package"), or if you really need
your actions to be on a different package, you can create a new one in
xml, that extends the one that contains the interceptor, and use
@ParentPackage to point to it.
does that make some sense?

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
