Using Spring data JPA with MS SQL server - spring-data-jpa

Question

I am setting up an app using Spring data JPA, Hibernate and MS SQL Server and unfortunately, I got a beat messed up with the configurations.
I hope someone here code make things clearer:.
This is my mvc-dispatcher.xml which is the application context:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<context:component-scan base-package="com.yyy.yyy" />
<context:property-placeholder location="classpath:db.properties"/>
<!-- DATA BASE -->
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true" />
<property name="database" value="SQL_SERVER" />
</bean>
</property>
<property name="persistenceUnitName" value="punit" />
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClass}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.user}" />
<property name="password" value="${jdbc.pwd}" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<jpa:repositories base-package="com.yyy.yyy.yyy.repository"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
Now, I also have a persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="punit">
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect" />
<property name="hibernate.connection.url" value="${jdbc.url}" />
<property name="hibernate.connection.driver_class" value="${jdbc.driverClass}" />
<property name="hibernate.connection.username" value="${jdbc.user}" />
<property name="hibernate.connection.password" value="${jdbc.pwd}" />
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
</properties>
</persistence-unit>
</persistence>
I don't understand where should I put the DB connection data?
And I also cant connect to the DB (I get connection refused) - I am getting exception at server startup.
My project runs on Tomcat and I used https://github.com/SpringSource/spring-data-jpa-examples as a template.
EDIT
I managed to overcome the problems and publish to tomcat successfully,by removing the persistence XML file and use only the spring context file:
<?xml version="1.0" encoding="UTF-8"?>

</bean>
</beans>
The app now loads fine, but when I use my repository and call save, I get connection refused exception.
Anyone knows why?
Help please.

You are refering to db.properites file here:<context:property-placeholder location="classpath:db.properties"/>
Where is it located in the project?
