I kind of succeeded solving this by defining a new service provider, so my
resource gets injected.
Maybe I didn't do it quite right though, because it works only if I declare
my to be injected property of type java.lang.Object like this:
@Resource(name = "configParams")
public Object configParams;
The actual injected value is still of type sample.jndi.ResourceBean.
If I declare the injected property consistent with the type of the injected
value like this:
@Resource(name = "configParams")
public sample.jndi.ResourceBean configParams;
it fails like below
javax.ejb.EJBException: An unexpected exception occured while invoking the
setSessionContext method on the Stateful SessionBean instance; nested
exception is:
org.apache.xbean.recipe.MissingAccessorException:
org.apache.xbean.recipe.StaticRecipe can not be assigned or converted to
sample.jndi.ResourceBean: public sample.jndi.ResourceBean
sample.CalculatorImpl.configParams

this is my service provider definition
<ServiceProvider id="Default Params"
service="Resource"
types="sample.jndi.ResourceBean, ResourceBean"
factory-name="create"
class-name="sample.jndi.GenericObjectFactory">
</ServiceProvider>
and here the deploy config
<Resource id="configParams" type="sample.jndi.ResourceBean">
</Resource>
