Hi Fay,

yes both are in the same directory. I tried with and without mapping entry in persistence. For reference I attached the content of my source directory. It is a very tiny example

If someone wants to test this, please run Main.java.

Best regards, Lars

Hi Lars,
    I ran your example as a standalone one. and the PCEnhancer works for me.  Here is my persistence.xml:

    <persistence-unit name="person">
      <provider>com.ibm.websphere.persistence.PersistenceProviderImpl</provider>
      <mapping-file>META-INF/orm.xml</mapping-file>
       <class>datamodel.Person</class>
      <properties>
         <property name="openjpa.jdbc.DBDictionary" value=""/>
...


and my orm.xml:
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/ormorm_1_0.xsd"
    version="1.0">
    <entity class="datamodel.Person">
      <table name="MYAPPLICATION.PEOPLETABLE"/>
        <attributes>
            <id name="id" />
            <basic name="firstName" />
            <basic name="lastName" />
            <transient name="nonsenseField" />
        </attributes>
    </entity>
</entity-mappings>

 They are almost identical as yours. Did you put your orm.xml in the same directory as your persistence.xml?
