JPA not working with Tapestry 5.3.0

[saurabh . jain]

Hello,

 

I am working on integrating JPA with Tapestry 5.3.0.

I follow all steps mentions in site
http://tapestry.apache.org/integrating-with-jpa.html

 

But it throws following exception.

Unable to attach page Createperson: Exception constructing service
'PersistentFieldManager': Error invoking constructor
org.apache.tapestry5.internal.services.PersistentFieldManagerImpl(MetaDataLo
cator, Map) (at PersistentFieldManagerImpl.java:39) via
org.apache.tapestry5.internal.services.InternalModule.bind(ServiceBinder)
(at InternalModule.java:88) (for service 'PersistentFieldManager'): Error
invoking service contribution method
org.apache.tapestry5.hibernate.HibernateModule.contributePersistentFieldMana
ger(MappedConfiguration): Service contribution (to service
'PersistentFieldManager') conflicts with existing contribution (by
org.apache.tapestry5.jpa.JpaModule.provideEntityPersistentFieldStrategies(Ma
ppedConfiguration) (at JpaModule.java:137)).

 

My persistence.xml looks like as 

 

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

<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
persistence_2_0.xsd"

                version="2.0">

    <persistence-unit name="mydb" transaction-type="RESOURCE_LOCAL">

        <exclude-unlisted-classes>false</exclude-unlisted-classes>

        <properties>

            <property name="javax.persistence.jdbc.driver"
value="oracle.jdbc.driver.OracleDriver"/>

            <property name="javax.persistence.jdbc.url"
value="jdbc:oracle:thin:@172.20.1.115:5584:PLTDEV"/>

            <property name="javax.persistence.jdbc.user" value="rage"/>

            <property name="javax.persistence.jdbc.password" value="RAGE"/>

        </properties>

    </persistence-unit>

</persistence>

 

So please help what I do, to resolve the issue.
