spring migration from 3x to 4x to create hibernate session factory - spring

Question

I have a working project for spring XA transaction (http://www.javaworld.com/article/2077714/java-web-development/xa-transactions-using-spring.html). I modified the project downloaded and created pom.xml since i had to integrate it with my project. Initially i started with spring 3x. I got it working properly for spring 3x. Now i have to integrate it with hibernate, so in order to create hibernate session factory, i stated migrating it to spring 4x.
i have following entries in my config file for spring 3x
spring config file:
<?xml version="1.0" encoding="UTF-8"?>

and the pom.xml is having following entry:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
<version>3.0.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.0.7.RELEASE</version>
</dependency>
This works completely fine. Now if i want to migrate to spring4x, i make the following changes:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd ">
and update my pom.xml as follows:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
<version>4.0.0.RELEASE</version>
</dependency>
When i make the above changes and run my program, i get the following error:
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

Is there any other changes i have to make to get this project working with spring 4x.
I am trying to migrate to spring 4x since i have to make session factory as follows:
<bean id="sessionFactoryPayment"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSourcePayment" />
<property name="configLocation">
<value>classpath:payment.hibernate.cfg.xml</value>
</property>
</bean>

Answer 1

You are mixing Spring4 and Hibernate4. You do not need to change anything to your configuration to migrate your application to Spring 4. Your latest code snippet would be valid if you were trying to migrate your application to Hibernate4.
You can also omit the version altogher in your XML configuration as there is a mapping in the spring's jar that ensure that the latest available version is always used.

Answer 2

This is what i did to solve the problem: I have my original program working for 3.0.7.RELEASE. I was trying to migrate to spring4 since i wanted to make use of org.springframework.orm.hibernate4.LocalSessionFactoryBean. Migrating to spring4 causing above exception by making use of 4.0.0.RELEASE.
Hibernate 4 support was added to Spring Framework in 3.1. So i replaced 3.0.7.RELEASE with 3.1.0.RELEASE and the problem (exception) is gone.
