Difference between LocalSessionFactoryBean.hibernateProperties.hibernate.c3p0.timeout and HibernateTransactionManager.defaultTimeout

In our project's code, we are initialising slave DB Spring HibernateTransactionManager through xml as shown below:
<bean id="slaveSessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">com.swiggy.delivery.deliveryboy.model.dao.CustomMySql5Dialect</prop>
<prop key="hibernate.show_sql">${hibernate.slave.showSql}</prop>
<prop key="hibernate.format_sql">${hibernate.slave.formatSql}</prop>
<prop key="hibernate.connection.url">${hibernate.slave.connection.url}</prop>
<prop key="hibernate.connection.driver_class">com.mysql.jdbc.ReplicationDriver</prop>
<prop key="hibernate.connection.username">${hibernate.slave.connection.username}</prop>
<prop key="hibernate.connection.password">${hibernate.slave.connection.password}</prop>
<prop key="hibernate.c3p0.min_size">${hibernate.slave.c3p0.min_size}</prop>
<prop key="hibernate.c3p0.max_size">${hibernate.slave.c3p0.max_size}</prop>
<prop key="hibernate.c3p0.timeout">300</prop>
<prop key="hibernate.c3p0.max_statements">0</prop>
<prop key="hibernate.c3p0.idle_test_period">3000</prop>
<prop key="hibernate.c3p0.max_idle_time_excess_connections">60</prop>
</props>
</property>
</bean>
<bean id="slaveTransactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="slaveSessionFactory" />
<property name="defaultTimeout" value="10" />
</bean>
Here, I want to understand that for DB read timeouts, which value would be used during the transaction, the hibernate.c3p0.timeoutvalue of 300 ms or the defaultTimeout value of 10 ms.
I tried to go through both Spring and Hibernate docs for this but could not get a clear answer on whether the defaultTImeout would override the hibernate.c3p0.timeout or not.
My hunch is that the timeout value picked would be 300 ms. But cannot confirm that.

Tomcat Data Source Losing Connection With DB

I need a solution about tomcat datasource configuration.
I have 2 nginx front of my tomcats.These are feeding my app, these are Webservice.
Tomcat machines and database are in different ip blog so its going firewall in each request.
When i started my tomcats everythigs well.But for example after 10 hour our after 20 hour later everythings going bad.That tomcats can not set connection.All service down.I share my datasource file and hope you find some solution or some other suggestions other than datasource file.

Got the scenario . I changed the value of cron expression to run it in every 1 minute but it was still set to my previous value (i.e. early morning 3 AM) . i added below property and then new cron expression startd working ..
<property name="overwriteExistingJobs" value="true"/>

Strange Behavior packageToScan and annotatedClasses when using multiple sessionFactory?

So here it goes..
I have configured two jndi in my glassfish server for communicating two different databases.And in my applicationContext.xml I have following configuration
<!-- Database connection 1 STARTS HERE-->
<jee:jndi-lookup id="JNDI1" jndi-name="jdbc/db1"/>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="JNDI1" />
<!-- <property name="annotatedClasses">
<list>
<value>com.test.db1.Person</value> //THIS WORKS FINE
</list>
</property>-->
<property name="packagesToScan" value="com.test.db1" /> //THIS IS STRANGE
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.connection.autocommit">false</prop>
</props>
</property>
</bean>
<!-- Database connection 1 ENDS HERE-->
<!-- Database connection 2 STARTS HERE-->
<jee:jndi-lookup id="JNDI2" jndi-name="jdbc/db2" />
<bean id="sessionFactory2"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="JNDI2" />
<property name="packagesToScan" value="com.test.db2" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.connection.autocommit">false</prop>
</props>
</property>
</bean>
<!-- Database connection 2 ENDS HERE-->
In package com.test.db1 I have only Person class and in com.test.db2 package I have two entities named Employee and Company.
The problem occurs when I use packageToScan property in both SessionFactory beans all 3 tables are created in both databases.And when I explicitly define entity classes using annotatedClasses property tables are generated in relevant databases as configured in jndi.I am not getting why this kind of results I am getting while using packageToScan.
I'll be grateful If someone can explain me in detail.
Thank you

spring hibernate configuration using resource_local or jta by default?

may i know as my configuration is done directly on applicationContext.xml, i do not have persistence.xml . by default this is resource_loca or jta? do i need to add extra parameter if i want to use jta?

RESOURCE_LOCAL only applies to JPA EntityManager, not to a Hibernate SessionFactory. Hibernate's Spring integration is rather smoother than it is with JPA, and so the only thing that determines the transactional behaviour is which transaction manager you use with it (either HibernateTransactionManager or JtaTransactionManager). It'll work with either one without you having to explicitly configure the SessionFactory.
