I have a problem integrating Spring, Hibernate, and Apache DBCP. I have used the DBCPConnectionProvider from here.
I have the following xml configuration for the above said.
<context:component-scan base-package="com.my.app"/>
<tx:annotation-driven/>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

</bean>
When the database schema i.e. app is empty two tables will be created in mysql. But I am getting NullPointerException in the getConnection() method of the DBCPConnectionProvider that I mentioned. That means the dataSource is not instantiated. I think I have configured everything in the xml. What am I missing. How do you configure DBCP version 1.4 with Spring and Hibernate? Please provide your insights.
Here is the stack trace:

Don't do it like that. Configure the datasource you want to use in Spring as well as Hibernate. Ditch the hibernate.dbcp and hibernate.connection properties.
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/app"/>
<property name="username" value="foo"/>
<property name="password" value="bar"/>
// Other DBCP properties here
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"
<property name="packagesToScan">
<list>
<value>com.my.app.model</value>

<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
Just add the dataSource property to your AnnotationSessionFactoryBean as dependency and done. Note you don't need the configurationClass property as it is already annotation based.
A tip I wouldn't suggest using Commons-DBCP anymore as a datasource instead take a look at HikariCP as a better datasource implementation.
For more information in integrating/configuring Hibernate with Spring I suggest this section of the Reference Guide.

I am getting the following error after upgrading from Spring 4.3.2 to Spring 4.3.16:

This worked in Spring 4.3.2 up until 4.3.14. I see https://jira.spring.io/browse/SPR-16439 was backported to 4.3.15 so I am wondering if it changes the way I am supposed to use this class?
schedulerFactory had autowire="byName" on its configuration.
I am not sure why that was on there, but removing it seems to have fixed the exception.
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.

I overrided all ImprovedNamingStrategy methods and placed for them breakpoints, but methods were not called in debug mode.
I have only one hibernate factory, so mistake because of other instance is impossible.
I think, the problem is in the key "hibernate.ejb.naming_strategy" or no?

Hibernate 5 doesn't have any ImprovedNamingStrategy. It uses ImplicitNamingStrategy and PhysicalNamingStrategy interfaces. Strictly speaking, there is the class ImprovedNamingStrategy, for an example, in the Hibernate 5.1. But you can't use it to configure the SessionFactory.
An example to set ImplicitNamingStrategy
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="implicitNamingStrategy">
<bean class="com.github.fluent.hibernate.cfg.strategy.hibernate5.Hibernate5NamingStrategy">
<property name="tablePrefix" value="spring_" />
</bean>
</property>
</bean>
You can use hibernate.implicit_naming_strategy and hibernate.physical_naming_strategy properties as well
<bean id="sqlSessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.implicit_naming_strategy">
com.stub.utilities.dao.sql.hibernate.ImplicitNamingStrategy
</prop>
<prop key="hibernate.physical_naming_strategy">
com.stub.utilities.dao.sql.hibernate.PhysicalNamingStrategy
</prop>
</props>
</property>
<property name="annotatedClasses"/>
</bean>
</beans>
You can refer my other answer about how to implement LowerCaseNamingStrategy

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">

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
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.
