Hi,

During startup the tomcat server. Found the error as below:

could not instantiate CacheProvider: net.sf.ehcache.hibernate.Provider

Do u have any idea?

hauboon,
Not sure if this will help but ...
It appears that if no cache property is defined Hibernate uses ehcache. My problem was I had defined a cache and it kept looking for ehcache. The real problem was a space inside the double quotes (see below).
Code:
<!-- Wrong -->
      <property name="hibernate.cache.provider_class ">net.sf.hibernate.cache.HashtableCacheProvider</property>
<!-- Right -->
      <property name="hibernate.cache.provider_class">net.sf.hibernate.cache.HashtableCacheProvider</property>



The other option is to download ehcache at http://ehcache.sourceforge.net/

Either put ehcache.jar in your classpath or specify another cache provider
