legacy spring service layer

[rshan.bob.shanahan.alascorp.com]

I have a legacy Spring based application that has a dao/domain layer and a service layer over that. The dao/domain layer uses Spring's HibernateDaoSupport. The service layer beans are injected with daos. The service and domain components are used by a couple of Struts applications and lazy loading is managed with Spring's OpenSessionInViewFilter.

I'm developing a Seam proof-of-concept, hoping to realize the benefits of RESTful JSF, ajax, etc., etc. and breathe new life into these applications. However, I'm at a loss with regard to configuring a persistence context for a legacy Spring dao based architecture.

   <!-- how do you configure this for legacy spring dao? 
   <persistence:managed-persistence-context name="entityManager"
                                      auto-create="true" 
                                      entity-manager-factory="#{entityManagerFactory}" /> 
   -->
   
   <spring:spring-transaction platform-transaction-manager="#{transactionManager}" join-transaction="true" auto-create="true"/>
   <security:identity authenticate-method="#{authenticator.authenticate}"/>

And finally, my authenticator, which fails with a LazyInitializationException, as expected, since it has no persistence context to manage its session scope.

@Scope(EVENT)
@Name("authenticator")
public class Authenticator
{
    @In Identity identity;
    @In ("#{authenticationManager}") private AuthenticationManager _authManager;
    
    public boolean authenticate()
    {
        Authentication a = new UsernamePasswordAuthenticationToken(identity.getUsername(), identity.getPassword());
        
        try
        {
            hibernateSession.setFlushMode(FlushMode.AUTO);
            
            Authentication principal = _authManager.authenticate(a);
            
            identity.setUsername(principal.getName());
            
            for(GrantedAuthority g: principal.getAuthorities())
            {
                identity.addRole(g.getAuthority());
            }
        }
        catch(AuthenticationException e)
        {
            return false;
        }
        
        return true;
    }
}

Hava you read this article?.

[rshan.bob.shanahan.alascorp.com]

I read the article and was inspired by it to devise a configuration that requires no alterations to the legacy Spring components. Seems straightforward, however, the app fails on startup with a java.lang.IllegalStateException: No active application scope

Prior to the exception, the log conveys Seam component loading, which requires an active application context, doesn't it? So what's happening to the active application scope?

HELP! PLEASE!

[gjeudy]

You need Seam to bootstrap the spring container and not the servlet container bootstrap the spring container.

So remove:

<listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>

from your web.xml and add the following in your components.xml:

<spring:context-loader config-locations="/WEB-INF/classes/applicationContext.xml" />

Modify config-locations at your leisure, depending where your spring config resides..

Let us know how it goes.

[rshan.bob.shanahan.alascorp.com]

I did as you suggested. Recall from my ContextLoaderListener config that my appContext has a parent. I configured like this:

components.xml

    <spring:context-loader>
         <spring:config-locations>
              <value>classpath:com/i2i/services/beanRefFactory.xml</value>
              <value>/WEB-INF/beanRefFactory.xml</value>
         </spring:config-locations>
    </spring:context-loader>

/WEB-INF/beanRefFactory.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
            "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>
     <bean id="i2i.web" lazy-init="false"

          </constructor-arg>
          <constructor-arg>
               <ref bean="i2i.services" />
          </constructor-arg>
     </bean>
</beans>

JBoss started cleanly, including loading of all Spring beans, and I was hopeful that something might actually work first try. No such luck. Seam can't find the PlatFormTransactionManager.

Any ideas?

[rshan.bob.shanahan.alascorp.com]

BTW, I was able to get the seam component working by setting auto create to false and using

@In(create=true)

In this configuration, there was no issue finding the PlatformTransactionManager.

Nevertheless, I'd like to be able get the components.xml spring:context-loader working and still interested in ideas why using beanRefFactory.xml style Spring bean loading would be problematic.

[rshan.bob.shanahan.alascorp.com]

Looking at the source of the spring context-config class, I can see that this will never work. Are there any plans to support ContextSingletonBeanFactoryLocator style context loading so that multiple webapps can share the same service layer context plus allow for setting context's parent?

[gjeudy]

I never tried a beanRefFactory.xml setup combined with Seam. Check out the JIRAs and file a new one if none exist that address your issue.

If your integration is mission-critical (there is no going back) then I suggest you override the Seam ContextLoader by declaring the same @Name but with a higher precedence Application and whip up your own implementation.

@Scope(ScopeType.APPLICATION)
@BypassInterceptors
@Startup(depends="org.jboss.seam.ioc.spring.springELResolver")
@Name("org.jboss.seam.ioc.spring.contextLoader")
@Install(value = false, precedence = APPLICATION)
public class ContextLoader

Thanks for the help.

New Jira issue:
https://jira.jboss.org/jira/browse/JBSEAM-3639

One last question as it relates to legacy Spring integration... all of the examples I've been able to find are based on Spring's Jpa template (EntityManager). Is it possible to create a Spring based persistence context with a traditional HibernateTemplate based persistence context? If so, how?

Examples look like this:

<persistence:managed-persistence-context name="entityManager"
                                      auto-create="true" 
                                      entity-manager-factory="#{entityManagerFactory}" />

My legacy Spring service component has HibernateTemplate based DAOs that are based on Hibernate SessionFactory.

Is it correct to do this?:

<persistence:managed-persistence-context name="entityManager"
                                      auto-create="true" 
                                      entity-manager-factory="#{sessionFactory}" />

If so, should the Spring DAOs then be injected with a SeamManagedSessionFactoryBean or a SeamManagedEntityManagerFactoryBean?

Or should the persistence context be defined in terms of Hibernate as in?:

<persistence:managed-hibernate-session name="hibernateSession" auto-create="true" session-factory="#{sessionFactory}"/>

[gjeudy]

If you are dealing with Spring's HibernateTemplate then I assume you use the SessionFactory not EntityManagerFactory in which case you will have to use the Seam native hibernate integration with:

<persistence:managed-hibernate-session name="hibernateSession" auto-create="true" session-factory="#{sessionFactory}"/>

likewise inject a SeamManagedSessionFactoryBean in your Spring DAOs.

I don't see any reasons why this shouldnt work, both Seam native hibernate integration and JPA integration are symmetrical to the only difference of the programming API you get.
