The chosen transaction strategy requires access to

问题:

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

daoConfig.xml

in my daoconfig.xml i given path for persistence.xml and this is my persistence.xml file

  <?xml version="1.0" encoding="UTF-8"?>

here i am specifying my orm mapping file name
orm.xml file is

when i am trying to run my server .i Am getting the error

give me any suggestions

回答1:

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.

The creation of the entity manager factory fails because you specified JTA as 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.)

Add this to your 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:

<property name="hibernate.transaction.manager_lookup_class"  
 value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
