Re: [eclipselink-users] descriptor.disableCacheHits() does not disable cache hits 
Again thanks for the quick reply

My problem still the same: How can is see that now cache is being hit not
the databse

My spring configuration file enable to show sql

	<bean id="entityManagerFactory"
	
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="jpaVendorAdapter">
			<bean
				class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter">
				<property name="showSql" value="true" />
				<property name="generateDdl" value="false" />
				<property name="databasePlatform"
value="org.eclipse.persistence.platform.database.oracle.OraclePlatform"/>
			</bean>
		</property>
		<property name="loadTimeWeaver">
			<bean
				class="org.springframework.instrument.classloading.SimpleLoadTimeWeaver"
/>
		</property>
	</bean>




Modified Code snippet to link pk and entity manager refresh

@Cache (
	    type=CacheType.WEAK,
	    expiry=600000,
	    refreshOnlyIfNewer=true,
	    disableHits=false,
	    coordinationType=CacheCoordinationType.SEND_NEW_OBJECTS_WITH_CHANGES
	    )
@NamedQueries( {
		@NamedQuery(name = "CodFlexCodesB.findAll", 
		            query = "select o from CodFlexCodesB o"),
		@NamedQuery(name  = "CodFlexCodesB.timeValidity", 
				    query = "SELECT em FROM CodFlexCodesB em " +
				    		"WHERE em.id = :pk AND em.codFlexCodeSystemsB.id =  :id AND " +
				    		"(em.startDate <= :endDate OR  :endDate IS NULL ) AND (em.endDate
>= :startDate OR  em.endDate IS NULL) ",
				    hints = {@QueryHint(name=QueryHints.CACHE_USAGE,
value=CacheUsage.ConformResultsInUnitOfWork
),@QueryHint(name=QueryHints.REFRESH,value=HintValues.TRUE)}
				    
				   )
})



Still log shows two quries
