Native EclipseLink: enable second level cache for some objects

Our project uses the "old" (non-JPA) version of EclipseLink. These mappings are configured using the Workbench application (which generates XML configuration files and some Java code).

What we see in the workbench tool: it looks like for all objects, the cache of which is enabled with the Shared isolation level (default).

What we see in the application: no entity is cached

What we need: Enable second-level caching for only a few objects

EDIT

Configuration in Workbench EclipseLink:

Generated XML config:

  [...]
  <refresh-cache-policy/>
  <caching-policy/>
  [...]

      

        
        
        
      

    

Generated project code:

    // ClassDescriptor Properties.
    descriptor.useSoftCacheWeakIdentityMap();
    descriptor.setIdentityMapSize(100);
    descriptor.useRemoteSoftCacheWeakIdentityMap();
    descriptor.setRemoteIdentityMapSize(100);
    descriptor.setReadOnly();
    descriptor.setAlias("SomeAlias");

    // Cache Invalidation Policy
    TimeToLiveCacheInvalidationPolicy policy = new TimeToLiveCacheInvalidationPolicy(1000);
    policy.setShouldUpdateReadTimeOnUpdate(false);
    descriptor.setCacheInvalidationPolicy(policy);

    // Query Manager.
    descriptor.getQueryManager().checkCacheForDoesExist();
