Subject Orchestra, Spring and AspectJ
Date Sun, 05 Dec 2010 00:23:02 GMT
Hi

I'm having LazyInitializationException in my web application even if I'm 
using Orchestra's conversation scope. I checked already my Spring and 
Orchestra configurations and everything should be ok. Has it maybe 
something to do because I use the AspectJ support from Spring for the 
annotated transactions? I can see in my log files, that at the end of 
the transaction the entity manager is always closed and thats definitly 
not what I want when I use the conversation scope:

DEBUG [http-8080-5] org.hibernate.engine.StatefulPersistenceContext 
initializing non-lazy collections
TRACE [http-8080-5] org.hibernate.jdbc.JDBCContext after autocommit
DEBUG [http-8080-5] org.hibernate.jdbc.ConnectionManager aggressively 
releasing JDBC connection
TRACE [http-8080-5] org.hibernate.impl.SessionImpl after transaction 
completion
DEBUG [http-8080-5]

EntityManager
TRACE [http-8080-5] org.hibernate.impl.SessionImpl closing session
TRACE [http-8080-5] org.hibernate.jdbc.ConnectionManager connection 
already null in cleanup : no action
ERROR [http-8080-5] org.hibernate.LazyInitializationException failed to 
lazily initialize a collection of role:

The handling from the JSF beans works perfect, I have only the problem 
with the persistence.

The application run's on tomcat6 (with the spring-instrument-tomcat.jar 
in the classpath), Spring 3.0.3 and JPA 2.0 (Hibernate).

Best regards,

And here is the application.xml configuration:
