Subject Re: Why is CXF creating a new instance of my controller for each request?
Date Fri, 05 Aug 2016 10:04:40 GMT
Hi David

By default JAX-RS assumes a service lifecycle is per-request.
When one uses CXFServlet directly it is nearly always a singleton unless 
a user specifies a non-singleton scope in Spring.

So I'd need to configure it somehow at the Tomee level, I've asked at 
#openejb, here is what Romain (@rmannibucau) said:

Either disable a Tomee jaxrs subsystem classpath scanning to avoid a 
double scanning
use JAX-RS Application.getSingleton
@ApplicationScoped @javax.ejb.Singleton and @javax.inject.Singleton (but 
this one is a bit slower casue the lookup is done per invocation where 
@AppScoped is cached)

By the way, I saw at "#openejb" a user who I thought might've been 
yourself. If it is indeed the case then please talk to Romain who is the 
TomEE expert who can always help.

Cheers, Sergey

then I noticed that when I got into the controller method after handling a web request, the
service object was null, even though I saw the setter breakpoint being hit.  I then discovered
that CXF appears to be creating a new instance of the controller for every request, and the
controller instance that it uses isn't wired up.
