Cannot inject Spring-bound HibernateSessionFactory to Seam-managed Hibernate Session
------------------------------------------------------------------------------------

                 Key: JBSEAM-1636
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1636
             Project: JBoss Seam
          Issue Type: Bug
          Components: Spring
         Environment: Tomcat 6.0.13, Spring 2.0.6, Seam CVS 08072007
            Reporter: Przemyslaw Jaskierski
            Priority: Minor
         Attachments: seamComponentNamespaceStackTrace.txt.zip, springELResolverStackTrace.txt.zip, springStartedFromSeam.txt.zip

Filling this PR as requested by Mike.
For a full story please read related topic. As you requested I tried to reproduce environment from my previous unsuccessful attempts. It's a little bit frustrating but after assembling it once again now Spring EL resolver seams to working somewhat in some aspects. But let's try to report step by step.

1. Spring-EL approach: Spring-bound session factory, referenced in components, Spring EL resolver put into faces-config. There are two cases:
1.a. I have Seam-session-scoped bean that in @Create tries to get Hibernate session and retrieve some information from RDBMS. I have abstracted Seam-managed-hibernate-session access, and this additional layer simply invokes Component.instance(NAME_OF_SEAM_MANAGED_HIBERNATE_SESSION_COMPONENT_DECLARED_IN_COMPONENTSXML) instead of relying in @In. This layer is completely pluggable and allows to select HibernateSession manager (Seam, Spring OSIV, custom one for Test) and inject it into data access layer.
Ok, so this @Create call renders a bunch of extremely huge stacktreace (WORKED in Microncontainer/Seam 1.3 combo flawlessly). You can see these stracktraces in springELResolverStackTrace.txt.zip file.
1.b. Every following HibernateSession access seams to WORK now (I swear It didn't :(). Strange... Anyway I cannot use it because of 1.a.

1.1 components.xml
    <persistence:managed-hibernate-session name="seamManagedHibernateSession" auto-create="true" 
		session-factory="#{hibernateSessionFactory}"/>
    <transaction:hibernate-transaction session="#{seamManagedHibernateSession}"/>


2. Spring namespace approach: Spring-bound session factory, referenced in components.xml, <seam:component> added to Factory definition in application context:

<bean id="pecpHibernateSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" scope="prototype">
    	<seam:component class="org.hibernate.impl.SessionFactoryImpl"/>
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:conf/hibernate/hibernate.cfg.xml" />
        <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"/>
        <property name="namingStrategy">
        	<bean class="egd.persistence.hibernate.extensions.UnderscoreAwareNamingStrategy"/>
        </property>
</bean>

Spring listener put AFTER Seam listener in web.xml. App contexts configured from Spring listener.  Result: java.lang.IllegalStateException: No active application scope. See seamComponentNamespaceStackTrace.txt.zip.

2.1. components.xml like in 1.1.


3. <spring:context-loader> approach. Everything like in point 2., but Spring listener removed from web.xml.
Result: "Seam cannot wrap JDK proxied IoC beans. Please use CGLib or Javassist proxying instead" - stracktrace in 
springStartedFromSeam.txt.zip

3.1. components.xml
     <core:init transaction-management-enabled="true" debug="true"/>      
    <core:manager conversation-timeout="120000" 
                  concurrent-request-timeout="500"
                  conversation-id-parameter="k"/>
    <spring:context-loader config-locations="classpath:conf/spring/core.xml,
            classpath:conf/spring/persistence-common.xml,
			classpath:conf/spring/persistence-hibernate.xml,
			classpath:conf/spring/statistics.xml"/>
    <persistence:managed-hibernate-session name="seamManagedHibernateSession" auto-create="true" 
		session-factory="#{hibernateSessionFactory}"/>
    <transaction:hibernate-transaction session="#{seamManagedHibernateSession}"/>


That's all info I can get about this. Having a model example of such integration that I was struggling with would be a quite nice POC.
Now I need to get back to code, because I lost a lot of time lately :). Will happy live with my current workaround for a while :).
