Unable to connect to database after migrating to Hibernate 4

I am trying to update hibernate from 3.6.10.Final to 4.3.6.Final. With 3.6.10 everything worked fine. I renamed the changed classes to the new classnames and get no errors on that side, but when I run the webapplication I get an error:
2015-06-12 10:44:35.345 ERROR SchemaUpdate:201 - HHH000319: Could not get database metadata
java.sql.SQLException: Connections could not be acquired from the underlying database!
With hibernate 3.6.10 the application-context.xml looked like this:

Did I mis some change which is causing the connection to fail now?

You need to remove the following properties:
<prop key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider
<prop key="hibernate.c3p0.min_size">3</prop>
<prop key="hibernate.c3p0.max_size">50</prop>
<prop key="hibernate.c3p0.timeout">1800</prop>
<prop key="hibernate.c3p0.idle_test_period">100</prop>
Hibernate already uses the external dataSource so it doesn't use the internal ConnectionProvider mechanism.
You are getting an exception, because Hibernate might ignore the properly configured dataSource and try to use the C3P0ConnectionProvider, for which you don't supply an URL, user, password.

Exit program on Spring jpa/Hibernate connection exception

I want my program to exit if it cannot connect to the database on startup. Currently this connection is setup using the following:
application-context.xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>${db.driver}</value>
</property>
<property name="url">
<value>${db.url}</value>
</property>
<property name="username">
<value>${db.username}</value>
</property>
<property name="password">
<value>${db.password}</value>
</property>
</bean>
<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>
<property name="packagesToScan" value="com.template" />
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.ejb.naming_strategy">${naming_strategy}</prop>
<prop key="hibernate.connection.autoReconnect">true</prop>
<prop key="hibernate.connection.autoReconnectForPools">true</prop>
<prop key="hibernate.connection.check-valid-connection-sql">SELECT 1</prop>
<prop key="hibernate.connection.failOverReadOnly">false</prop>
<prop key="hibernate.connection.maxReconnects">${maxreconnects}</prop>
<prop key="hibernate.connection.initialTimeout">${reconnect.interval}</prop>
</props>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
Repository:
#Repository
public interface Repository extends CrudRepository<Object, String> {
}
It's not obvious where I should place code to catch the runtime exceptions created by the connection failure. Are there any other settings I can use to exit if the database doesn't exist.

Usually, spring will stop, if it could not create a bean at startup. If DB connection fails, then it will stop automatically anyway. Do you want to catch that exception, and do something before exit ?

Unable to start hibernate session factory bean

Here is the exception
Caused by: java.lang.IllegalStateException: Expected method not found: java.lang.NoSuchMethodException: org.hibernate.cfg.Configuration.addAnnotatedClass(java.lang.Class)

What am I missing here?

It looks like your hibernate annotations jar file is the incorrect version.
You should already have hibernate-core as a dependency. If so you can comment out your hibernate-annotations dependency in your POM file.

The solution was to use hibernate 3 and Adding this
<prop key="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</prop>
So the final config is
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="packagesToScan" value="sample.model"/>
<property name="annotatedPackages">
<list>
<value>sample.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect"> org.hibernate.dialect.H2Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</prop>
</props>
</property>

Quartz NotSerializableException Exception

What should i do? Thanks in advance.

Use inner classes. No serialization is required.
http://shyarmal.blogspot.com/2011/07/quartz-20-schedule-cron-with-spring.html

EmailSenderJob and all of its members need to implement Serializable.
