Class EclipseLinkJPACacheLoader

java.lang.Object
com.tangosol.util.Base
oracle.eclipselink.coherence.integrated.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 the Coherence Cache Loader that should be used with EclipseLink Coherence interceptors and redirectors set in your PeristenceUnit. No special Persistence Unit updates should be required when used with this Cache Loader.

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 integrated EclipseLinkJPACacheLoader can be configured.

 <cachestore-scheme>
    <class-scheme>
       <class-name>oracle.eclipselink.coherence.integrated.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>
