Balazs Pataki commented on JBSEAM-3965:
---------------------------------------
Maybe it is a different issue, but it seems to be impossible to register a class as both
as @Provider and a Seam component (with @Name).
In ResteasyBootstrap there's this warning:
log.warn("not registering as provider Seam component, must be
APPLICATION or STATELESS scoped: "
+ seamComponent.getName());
however in ResteasyDispatcher i says:
throw new RuntimeException(
"Registration of STATELESS Seam components as RESTEasy
providers not implemented!"
);
This means that at the end only Scope.APPLICATION is allowed. However if I annotate my
StringConverter subclass like this:
@Name("MyConverterComponent")
@Scope(ScopeType.APPLICATION)
@Provider
it won't get registered or won't be invoked at all when marshalling the method
parameters of my REST calls.

@Providers not working - ResteasyDispatcher registers components and
providers in wrong order

Key: JBSEAM-3965
URL:
https://jira.jboss.org/jira/browse/JBSEAM-3965
Project: Seam
Issue Type: Bug
Components: WS
Affects Versions: 2.1.1.CR1
Reporter: Balazs Pataki
Assignee: Jozef Hartinger
While using the latest nightly build (from 2009.02.19) I found that my @Provider
annotated class is not used by Seam+RESTEasy. It seemed to be loaded but not used by
injection mechanism. By debugging the code I found out that it is not used because
org.jboss.seam.resteasy.ResteasyDispatcher#onStartup() first registers the resources and
after that the providers. However, as part of the resource registration the injection
mechanism including the converters are set up, however at this point the converters
(providers) have not been loaded.
It seems to first load the providers and then the resources.
This is my patch that worked in my setup:
