Hi All,
I am using spring-hibernate in my application and IDE as eclipse/myeclipse. I have created the mappings for the huge database(about 1000+ tables). This is done using myEclipse hibernate plugin.

I have configured an application in OC4J (10.1.3.0.0). On starting the of the application server all the spring-beans are loaded. Configuration related to the ORM as follows

[COLOR="Blue"]<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>datasource.properties</value>
<value>application.properties</value>
</list>

</property>
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>${jdbc.driverClassName}</value>
</property>
<property name="url">
<value>${jdbc.url}</value>
</property>
<property name="username">
<value>${jdbc.username}</value>
</property>
<property name="password">
<value>${jdbc.password}</value>
</property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="mappingDirectoryLocations" >
<list>
<value>com/iba/ehis/dobj</value>
</list>
</property>


<property name="hibernateProperties" >
<props>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>

<prop key="jta.UserTransaction">java:comp/UserTransaction</prop>
<prop key="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JOTMTransactionManagerLookup</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</prop>

<prop key="hibernate.cache.provider_class">org.hibernate.cache.TreeCacheProvider</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
<prop key="hibernate.cache.use_second_level_cache">true</prop>

<prop key="hibernate.cache.use_structured_entries">true</prop>
<prop key="hibernate.generate_statistics">true</prop>
<prop key="hibernate.cache.use_minimal_puts">true</prop>
</props>
</property>

</bean>

When I start the application server instance I am getting stack overflowerror. What could be the possible reason. Is there any configuration where i can restrict the class loading process to the required classes.
