Changes do not persists to DB?

Question

Hi all,
I managed to configure coherence but changes that I made do not persists to DB?
My cache-config.xml:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
  <caching-scheme-mapping>
    <cache-mapping>
        <cache-name>*</cache-name>
        <scheme-name>distributed-eclipselink</scheme-name>
    </cache-mapping>
  </caching-scheme-mapping>
  <caching-schemes>
    <distributed-scheme>
      <scheme-name>distributed-eclipselink</scheme-name>
      <service-name>EclipseLinkJPA</service-name>
          <serializer>
        <class-name>oracle.eclipselink.coherence.integrated.cache.WrapperSerializer</class-name>
      </serializer>
      <backing-map-scheme>
        <read-write-backing-map-scheme>
          <internal-cache-scheme>
            <local-scheme/>
          </internal-cache-scheme>
          <!-- Define the cache scheme -->
          <cachestore-scheme>
            <class-scheme>
              <class-name>oracle.eclipselink.coherence.integrated.EclipseLinkJPACacheStore</class-name>
              <init-params>
                <init-param>
                  <param-type>java.lang.String</param-type>
                  <param-value>{cache-name}</param-value>
                </init-param>
                <init-param>
                  <param-type>java.lang.String</param-type>
                  <param-value>HRPU</param-value>
                </init-param>
              </init-params>
            </class-scheme>
          </cachestore-scheme>
        </read-write-backing-map-scheme>
      </backing-map-scheme>
      <autostart>true</autostart>
    </distributed-scheme>
  </caching-schemes>
</cache-config>I'm trying to use TopLink Grid Cache Configuration.
Thanks in advance.

Ah. I missed that. If you are using container managed transactions then you need to change from RESOURCE_LOCAL to JTA and set the target-server property. You also need a JTA datasource. Here's an example from http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial#JTA_Datasource
Note that in an EE application there is no need to list your classes.
<persistence version="1.0" 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 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="example" transaction-type="JTA">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <jta-data-source>OracleDS</jta-data-source>        
    <properties>
      <property name="eclipselink.target-server" value="WebLogic_10"/>
      <property name="eclipselink.logging.level" value="FINEST"/>
    </properties>
  </persistence-unit>
</persistence>--Shaun
