Hi, thanks for the quick answer. The code is quite simple, it just has
a few "if"s and I don't touch the channel during the method until the
"send" call. I've pasted underneath the important parts. As I said,
the implementation works perfectly until the @Transactional annotation
is put into its interface, so I believe it can't have nothing to do
with the code. Hope you can get something out of it. What do you think
could be the problem?
Implementation:
... //package, other imports
import javax.annotation.Resource;
import xxx.yyy.services.PersistenceService;
public class PersistenceServiceImpl implements PersistenceService,
MessageExchangeListener {
@Resource
private DeliveryChannel channel;
public void onMessageExchange(MessageExchange exchange)
throws MessagingException {
...
... //channel never used here
...
channel.send(exchange); // throws NPE
}
Interface:
import org.springframework.transaction.annotation.Transactional;
@Transactional
public interface PersistenceService {
...
}
xbean.xml:
...
<bean id="xxx.yyy.services.persistenceService"
class="xxx.yyy.services.impl.PersistenceServiceImpl" />
<bean:endpoint service="ns:persistenceService"
endpoint="persistenceService"
bean="#xxx.yyy.services.persistenceService" />
