cache.getCacheManager() returns null.

[vinshar <vi...@gmail.com>]

Hi,

Below code prints null. is this expected? is there any way to get Ignite
instance from a cache instance?


ignite = Ignition.start("cache-server-test-node.xml");
		System.out.println("#################################################
"+ignite.cache("TEST_REPLICATED").getCacheManager());

below is cache configuration

<bean class="org.apache.ignite.configuration.CacheConfiguration">
					<property name="name" value="TEST_REPLICATED" />
					<property name="cacheMode" value="REPLICATED" />
					<property name="managementEnabled" value="true" />
					<property name="statisticsEnabled" value="true" />
					<property name="evictionPolicy">
						<bean
class="org.apache.ignite.cache.eviction.fifo.FifoEvictionPolicy">
							<property name="maxSize" value="20000" />
						</bean>
					</property>
					<property name="startSize" value="21000" />
				</bean>


Regards,
Vinay

I couldn't find any useful example on this.

However, you can refer to this test that showcases how it works in practice

Is there any documentation or example to use jcache with ignite as
implementation?

Hi Vinay,

getCacheManager() will return the instance of JCache manager [1] if you used
one to create a cache. If you created it using Ignite API, it will be null.

To get an Ignite instance from IgniteCache do this: 'Ignite ignite =
cache.unwrap(Ignite.class)'
