I have found a solution for @Resource issue. Thanks to that conversation:
http://forums.java.net/jive/message.jspa?messageID=239405
I followed the solution provided by 'hildo' and added the "name" of
the resource like this:
----------------------------------------
@Resource(mappedName = "jms/IVTCF", name = "eis/IVTCF")
private ConnectionFactory ivtcf;
@Resource(mappedName = "jms/IVTQueue", name = "eis/IVTQueue")
private Queue ivtQueue;
----------------------------------------
Notice the "eis/" prefix of the "name" attribute.
So now, everything works perfect (because NamingManagerImpl does not
try to return a copy of resources).
I can use that injected resources to send messages, because there is
no longer NotSerializableException when creating that bean.
The other problem still remains: I cannot deploy MDB.
I was trying everything like adding a >name="eis/IVTQueue" into @MessageDriven<
or declaring extra @Resource annotation on the MDB class and binding
mappedName to name and then using that name in @MessageDriven and
everything I found possible to do, but always the same:
MDB00017: [eis/IVTQueue]: Exception in creating message-driven bean
container: [com.sun.enterprise.connectors.ConnectorRuntimeException:
Could not find physical destination : null]
com.sun.enterprise.connectors.ConnectorRuntimeException
com.sun.enterprise.connectors.ConnectorRuntimeException: Could not
find physical destination : null
The stack trace was attached few posts above (wmqtest-stacktrace_2.txt)
Do you think I should start a new topic on this problem?
Thanks,
