javax.persistence.PersistenceException: No Persistence provider for EntityManage

还发工具：IDEA14+jdk1.7。

文件结构以及hibernate对应的jar包：如附件中的各图所示。

persistence.xml代码：

<persistence 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"
   version="2.0">
   <persistence-unit name="j2cmsSSH" transaction-type="RESOURCE_LOCAL">
   	  <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/> 
         <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>		
		 <property name="hibernate.connection.username" value="root"/>
		 <property name="hibernate.connection.password" value="111"/>
		 <property name="hibernate.connection.url" value="jdbc:mysql://127.0.0.1:3306/j2cms-ssh?useUnicode=true&amp;characterEncoding=utf8"/>
         <property name="hibernate.hbm2ddl.auto" value="update"/>
	     <property name="hibernate.show_sql" value="true"/>
	     <property name="hibernate.format_sql" value="true"/> 

	     <property name="hibernate.cache.region_prefix" value="org.j2cms"/>
	     <property name="hibernate.cache.use_query_cache" value="true"/>
	     <property name="hibernate.cache.use_second_level_cache" value="true"/>
	     <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>

      </properties>
   </persistence-unit>
</persistence>

 在启动tomcat时，出现异常：Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named j2cmsSSH
