4:10 p.m.
Env: Tomcat 6.0.13, Spring 2.0.6, Seam CVS snapshot 08-07-2007.
Task: I try to get Seam-managed hibernate session to work. Datasource and
HibernateSessionFactory are wired by Spring. Then I want to get to that factory from
within components.xml, to enable Seam-managed session.
I tried both ways to integratie Seam-Spring described in manual. Both failed totally. Both
attempts are listed below.
components.xml is the same in both cases:
| <core:init debug="false"/>
|
| <core:manager conversation-timeout="120000"
| concurrent-request-timeout="500"
| conversation-id-parameter="k"/>
|
| <persistence:managed-hibernate-session
name="pecpSeamManagedHibernateSession" auto-create="true"
| session-factory="#{hibernateSessionFactory}"/>
|
| <transaction:hibernate-transaction
session="#{pecpSeamManagedHibernateSession}"/>
|
1. Attempt: use <seam:component>: FAILED
1.1 Spring context file:
| <bean id="hibernateSessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
scope="prototype">
| <seam:component name="hibernateSessionFactory"
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="pecp.persistence.hibernate.extensions.UnderscoreAwareNamingStrategy"/>
| </property>
| <property name="hibernateProperties">
| <props>
| <prop
key="hibernate.hbm2ddl.auto">create</prop>
| </props>
| </property>
| </bean>
|
1.2. Result: nasty exception at startup (in both cases - when Seam listener is before
Spring listener in web.xml and the other way):

2.2 Spring EL resolver added to faces-config.xml,
2.3 Result: Seam enters infinite loop, looks like it simply instantiates
hibernateSessionFactory Spring bean over an over again.
