Singleton ehcache CacheManager warning fix

If you experience the following warning in your hibernate+ehcache application:

2008-11-20 13:02:42,937 WARN  (CacheManager.java:322) -
  Creating a new instance of CacheManager using the diskStorePath
  "D:\apache-tomcat-5.5.26\temp" which is already used by an
  existing CacheManager.
The source of the configuration was classpath.
The diskStore path for this CacheManager will be set to
  D:\apache-tomcat-5.5.26\temp\ehcache_auto_created_1227178962937.
To avoid this warning consider using the CacheManager factory
  methods to create a singleton CacheManager or specifying a
  separate ehcache configuration (ehcache.xml) for each
  CacheManager instance.

then you need to set the following in your hibernate.cfg.xml file:

<property name="hibernate.cache.provider_class">
  net.sf.ehcache.hibernate.SingletonEhCacheProvider
</property>

    you also need to add this line

    org.springframework.cache.ehcache.EhCacheManagerFactoryBean
    shared=true

    in your applicationcontext.xml

    In hibernate 3.6.1 you need this in persistence.xml (if using jpa)

    for ehcache 2.2.0
