Endless Loop Configuring Hibernate SessionFactory

[cepage]

Hi!

I am running a Spring application inside JBoss 3.2.5. I decided to play with the Hibernate integration, so I set up a simple DAO, and used a configuration very similar to what is in the docs.

But when I start up my server, it appears to go into an endless loop, attempting to build my SessionFactory over and over again. Are there any obvious problems in the configuration?

My springcontext.xml (which is loaded through a SingletonBeanFactoryLocator) contains the following:

   <!-- Hibernate -->
   <bean id="bigdealDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
      <property name="jndiName">
         <value>java&#58;/BigDealDS</value>
      </property>
   </bean>

   <bean id="bigdealSessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
      <property name="mappingResources">
         <list>
            <value>bigdeal.hbm.xml</value>
         </list>
      </property>
      <property name="hibernateProperties">
         <props>
            <prop key="hibernate.dialect">net.sf.hibernate.dialect.FirebirdDialect</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
         </props>
      </property>
      <property name="dataSource">
         <ref bean="bigdealDataSource"/>
      </property>
   </bean>

   <bean id="bigdealHibernateInterceptor" class="org.springframework.orm.hibernate.HibernateInterceptor">
      <property name="sessionFactory">
         <ref bean="bigdealSessionFactory"/>
      </property>
   </bean>

   <bean id="userDaoTarget" class="com.blued.bigdeal.dao.UserDaoBean">
      <property name="sessionFactory">
         <ref bean="bigdealSessionFactory"/>
      </property>
   </bean>

   <bean id="userDao" class="org.springframework.aop.framework.ProxyFactoryBean">
      <property name="proxyInterfaces">
         <value>com.blued.bigdeal.dao.UserDao</value>
      </property>
      <property name="interceptorNames">
         <list>
            <value>bigdealHibernateInterceptor</value>
            <value>userDaoTarget</value>
         </list>
      </property>
   </bean>

When I start up my server, the following messages are printed over and over in an endless loop:

16:24:26,376 INFO  [DefaultListableBeanFactory] Creating shared instance of singleton bean 'bigdealSessionFactory'

I can not find any other reports of this problem searching the forums, so I must be doing something really dumb!

Ach, I found it. There was an exception (ClassNotFound) being thrown during the bean instantiation, but DefaultListableBeanFactory masks it in debug-level logging.

Thanks anyway!

Sorry but I see you had this issue sometime in 2004 - I am having the same. Didn't mean to resurrect the thread. But is there any way you can guide me to resolve this?

Hi!

You might want to set logging level to debug to see if that can tell you if you too get a ClassNotFound exception, and if so, please post the stacktrace.

I have added the following to my log4j.properties file but still dont get any exception, just a continous loop.

#log4j.logger.org.hibernate=info
log4j.logger.org.hibernate=debug

### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug

### log just the SQL
#log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ###

I have taken hibernate and session related definitions out of my context xml. This upon run still loops but ends with this exception;

Sorry, no idea.
