Issues with listening on Events as a client node

[m-yassine1]

Hello,

I am trying to listen on some events, but I keep on getting NoSerilization Exception, and if I implement Serializable, I get a ClassNotFoundException.

I added the following property inside the XML file:

<property name="includeEventTypes">
	<list>
		<util:constant static-field="org.apache.ignite.events.EventType.EVT_CACHE_OBJECT_EXPIRED"/>
		<util:constant static-field="org.apache.ignite.events.EventType.EVT_CLUSTER_ACTIVATED"/>
		<util:constant static-field="org.apache.ignite.events.EventType.EVT_CLUSTER_DEACTIVATED"/>
	</list>
</property>

In my Java class, I added the following method:

    node.events().remoteListen(addExpiredQuote(), null, EventType.EVT_CACHE_OBJECT_EXPIRED);

Every time, it reaches this point, it throws the exceptions above.

I am creating a client node, that creates a cache in the cluster, and wants to listen on this event.
I had the following: node.cluster().forClientNodes(GRID_GAIN_QUOTE_CACHE)

Unfortunately, it starts up and I have a break point inside the function that should be called, but it never goes there when the object is evicted.

This is the cache configuration:

<bean class="org.apache.ignite.configuration.CacheConfiguration">
	<property name="name" value="RFQ_REST_QUOTE_CACHE"/>
	<property name="cacheMode" value="REPLICATED"/>
	<property name="rebalanceMode" value="SYNC"/>
	<property name="partitionLossPolicy" value="READ_ONLY_SAFE"/>
	<property name="eagerTtl" value="true"/>
	<property name="expiryPolicyFactory">
		<bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
			<constructor-arg>
				<bean class="javax.cache.expiry.Duration">
					<constructor-arg value="SECONDS"/>
					<constructor-arg value="30"/>
				</bean>
			</constructor-arg>
		</bean>
	</property>
</bean>

Can you please help?

Hi @m-yassine1,

Could you please share the implementation of your local listener and provide a full stack trace of the mentioned exceptions?
It would be great if you could upload your project to GitHub and provide a link.

By the way, node.cluster().forClientNodes(GRID_GAIN_QUOTE_CACHE) returns a cluster group for all client nodes that access the cache with the specified name. Client nodes do not store any data and so do not fire events like EVT_CACHE_OBJECT_EXPIRED.
