I am trying to include a jar in my struts2 project so that its actions are available to use in my main project. After adding the line
struts.convention.action.includeJars=.*?survey.*?
to my struts.properties and trying to redeploy to Tomcat with Maven, I get the errors:
WARN InterceptorBuilder 14 Nov 2012 09:58:09: Unable to load config class com.googlecode.scopeplugin.ScopeInterceptor at interceptor - jar:file:/other/dev/survey/webapp/target/survey-4.4-RC11-SNAPSHOT/WEB-INF/lib/survey-controller-4.4-RC11-SNAPSHOT.jar!/struts.xml:12:91 probably due to a missing jar, which might be fine if you never plan to use the bean-scope interceptor

and down the trace a bit further:

I’ve seen in other posts that this is because it can’t find the struts.xml because there are two struts.xml files – one in my main project, and another in the jar that I am including. Is there some way to exclude that dependency struts.xml if that is the issue? Or is this related to something else altogether?
Removing the includeJars line allows me to deploy my app, but I can’t access the actions in the jar that is being included.
Make sure you have the bean-scope interceptor in your struts.xml, and also as a dependency in your pom.xml.
