Class EclipseLinkJPACacheLoader

java.lang.Object

com.tangosol.util.Base

oracle.eclipselink.coherence.standalone.EclipseLinkJPACacheLoader

All Implemented Interfaces:

com.tangosol.net.cache.CacheLoader

Direct Known Subclasses:

EclipseLinkJPACacheStore

public class EclipseLinkJPACacheLoader
extends com.tangosol.util.Base
implements com.tangosol.net.cache.CacheLoader

This is a Coherence Cache Loader that can be used when EclipseLink is is desired as the persistence provider and no Cache Interceptors or Query Redirectors from the EclipseLink-Coherence integration are set within the Persistence Unit for the specific class. This is intended to be used where the application uses Coherence directly and the cache store/loader are used behind the scene to persist and load data.

Coherence Configuration: In order to use the integrated EclipseLinkJPACacheLoader or EclipseLinkJPACacheStore the Coherence configuration XML file must specify the loader/store class as well as providing parameters for the cache-name and JPA persistence unit name.

The following is an example of how the standalone EclipseLinkJPACacheLoader can be configured.

 <cachestore-scheme>
    <class-scheme>
       <class-name>oracle.eclipselink.coherence.standalone.EclipseLinkJPACacheLoader</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>coherence-pu</param-value> 
          </init-param> 
       </init-params>
    </class-scheme>
 </cachestore-scheme>
