I am using Spring 2.0.6 and Hibernate 3.2.x on apache tomcat5.5,now we planed to changed our hybernate mapping files into hybernate+jpa support mapping files. for that we created files like this

First of all, you're creating both a Hibernate SessionFactory and a JPA EntityManagerFactory. That does not make very much sense unless you have a very odd setup, and you should very likely throw out the SessionFactory configuration. You can either configure plain vanilla Hibernate, or you can configure JPA, you don't need both.
首先，您要创建 Hibernate SessionFactory 和 JPA EntityManagerFactory。除非您的设置非常奇怪，否则这没有多大意义，并且您很可能应该丢弃 SessionFactory 配置。您可以配置普通的 Hibernate，也可以配置 JPA，两者都不需要。
The creation of the entity manager factory fails because you specified JTAas the transaction type, but the JTA transaction manager lookup class is not defined. (You defined it in the Hibernate SessionFactory config, but not in your JPA config.)
实体管理器工厂的创建失败，因为您指定JTA为事务类型，但未定义 JTA 事务管理器查找类。（您在 Hibernate SessionFactory 配置中定义了它，但未在您的 JPA 配置中定义。）
Add this to your persistence.xml:
将此添加到您的persistence.xml：
<persistence-unit name="payhub" transaction-type="JTA">
...
<properties>
<property name="hibernate.transaction.manager_lookup_class"
value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/>
</properties>
</persistence-unit>

For those who are using Jboss AS, this configuration could be used:
对于使用 Jboss AS 的用户，可以使用此配置：
<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
