Re: local slsb lookup

dies, thanks for your message.
my POJO is not called from an EJB3-component or servlet or antyhing
else managed by the container.
it will called from a spring-component and the spring-component from
an external jcr-event(like a continous polling on the filesystem).
so no managed-component is involved until the lookup.


a local-ejb3-component can be looked up by any POJO within the same
classloader.
apparently glassfish does not provide this.
jboss does, though.
