and following persistence.xml file:

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:orm="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" version="2.0" xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd">     <persistence-unit name="com.sample:eventbusinessrules:2.6" transaction-type="jta">         <provider>org.hibernate.ejb.hibernatepersistence</provider>         <jta-data-source>java:jboss/datasources/exampleds</jta-data-source>         <class>com.sample.eventdata</class>         <exclude-unlisted-classes>true</exclude-unlisted-classes>         <properties>             <property name="hibernate.dialect" value="org.hibernate.dialect.h2dialect"/>             <property name="hibernate.max_fetch_depth" value="3"/>             <property name="hibernate.hbm2ddl.auto" value="update"/>             <property name="hibernate.show_sql" value="false"/>             <property name="hibernate.id.new_generator_mappings" value="false"/>             <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.jbossappserverjtaplatform"/>         </properties>     </persistence-unit> </persistence>

<marshalling-strategy>                 <resolver>mvel</resolver>                 <identifier>new org.drools.persistence.jpa.marshaller.jpaplaceholderresolverstrategy("com.sample.rules:eventbusinessrules:2.6", classloader)</identifier>                 <parameters/>             </marshalling-strategy>
