Can you post your hibernate.cfg.xml? Looks like it contains reference to the earlier version of EHCache.

Hi Jai,

here is the hibernate configuration file

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/hibernatetutorial</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password"></property>
<property name="hibernate.connection.pool_size">10</property>

</session-factory>
</hibernate-configuration>

Interesting, the hibernate.cfg.xml doesnt have any reference to the cache provider. But the exception stacktrace shows that while the session factory is being built, the cache provider is being configured. Are you sure, this is the hibernate.cfg.xml that is being refered by Hibernate? Is there any hibernate.properties in your classpath, which might be containing references to the cache provider?
