I think it's "prop.value =:identifier" (not ':identifier') otherwise
hibernate will consider you use the value ":identifier" and will not
replace it.

Looks like the component manager is not initialized when you are
trying to use Query Manager.
You are working in a specific servlet ? In that case you have to
initialize it. You can look at shared-test, webdav work made by Asiri
(in sandbox) or at standard sevlet initialization.
