Class EclipseLinkNativeCacheLoader

java.lang.Object
com.tangosol.util.Base
oracle.eclipselink.coherence.integrated.EclipseLinkNativeCacheLoader

All Implemented Interfaces:

com.tangosol.net.cache.CacheLoader

Direct Known Subclasses:

EclipseLinkNativeCacheStore

public class EclipseLinkNativeCacheLoader

extends com.tangosol.util.Base

implements com.tangosol.net.cache.CacheLoader

This is the Coherence Cache Loader that should be used with native EclipseLink configuration (sessions.xml) when Coherence interceptors and redirectors have been set through a customizer. This is equivalent to the JPA integration but is used when the pre-existing application uses native EclipseLink configuration.

Coherence Configuration: In order to use the integrated EclipseLinkNativeCacheLoader or EclipseLinkNativeCacheStore the Coherence configuration XML file must specify the loader/store class as well as providing parameters for the cache-name and session name. The 'sessions.xml' file must be available on the classpath or packaged within a jar within the META-INF directory.

The following is an example of how the integrated EclipseLinkNativeCacheLoader can be configured.

 <cachestore-scheme>
    <class-scheme>
       <class-name>oracle.eclipselink.coherence.integrated.EclipseLinkNativeCacheLoader</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>session name</param-value> 
          </init-param> 
       </init-params>
    </class-scheme>
 </cachestore-scheme>
