Re: ApplicationAware not triggering setApplication? Or, how best to reference a Connection pool?
My understanding is that the webwork API for ApplicationAware means that the
interceptor will have it's setApplication(Map applicationData); triggered
when the interceptor is run, thereby giving me access to the
applicationcontext.
ApplicationAware should be used with Actions not with interceptors, to
access application just use
public String intercept(ActionInvocation invocation) {
Map appScope = invocation.getInvocationContext().getApplication();
}

ApplicationAware not triggering setApplication? Or, how best to reference a Connection pool?
Hi folks - i'm trying to write an interceptor in struts2 that has access
to the ApplicationMap in the application context.
My understanding is that the webwork API for ApplicationAware means that
the interceptor will have it's setApplication(Map applicationData);
triggered when the interceptor is run, thereby giving me access to the
applicationcontext.
Problem is, it isn't :)
Here's the relevant parts...
public class DBInterceptor extends AbstractInterceptor implements
ApplicationAware {
...
@Override
public void setApplication(Map arg0) {
logger.info(Receiving applicationMap...);
this.applicationMap = arg0;
}
That logger is never triggered, 'applicationMap' is always null.
My struts.xml is:
interceptors
interceptor name=dbsetup
class=com.stonekeep.congo.interceptors.DBInterceptor /
interceptor-stack name=mystack
interceptor-ref name=dbsetup /
interceptor-ref name=defaultStack /
/interceptor-stack
/interceptors
(The goal here is to store a c3p0 connection pool object in the
application context, so that I can get a connection from it on every hit
- I assume this is the proper way to do this?)
Thanks, any help would be appreciated...

My understanding is that the webwork API for ApplicationAware means that the interceptor will have it's setApplication(Map applicationData); triggered when the interceptor is run, thereby giving me access to the applicationcontext. The ApplicationAware interface only applies to actions. It's actually a feature of the ServletConfigInterceptor. That interceptor inspects the target action for the interface and injects the Map if present. XWork's dependency injection uses the @Inject annotation on properties and constructions. It can inject beans it knows of, however the application context is not one of them. The simplest way to access the application context in your interceptor is via the ActionInvocation argument: ie. Map applicationContext = actionInvocation.getIncovationContext().getApplication(); You can also inject beans directly into you interceptor via spring or guice if you're using one of those DI frameworks.

That's done it, thank you very much. I was really stymied.
