Infinispan Cache store - "class not found" Exception in wildlfy addon module

Question

I am using the 11.0.7 Infinispan cache store which is configured with an XML file. I have imported that cache module in a Wildlfy server. I am using this dependency in my application. But when I try to fetch cache elements from cache, it gives me the exception ClassNotFound.

I have used this configuration:

<local-cache name="TaskStoreCache" statistics="false">
    <locking acquire-timeout="60000" />
    <persistence passivation="false">
        <rocksdb-store path=" C:\CacheStore\Data\TaskStoreCache" preload="false" shared="false" 
                       purge="false" read-only="false">
            <expiration path="C: \CacheStore\Expired\TaskStoreCache"/>
        </rocksdb-store>
    </persistence>
    <memory max-count="500"/>
    <encoding media-type="application/x-java-object"/> 
</local-cache>

And I used this serialization:

<serialization  marshaller="org.infinispan.commons.marshall.JavaSerializationMarshaller">
    <white-list>
        <regex>com.xyz.cache.*</regex>
        <regex>java.util.*</regex>                  
        <regex>java.lang.*</regex>  
    </white-list>
</serialization>

I am sure it is a class loading related issue. Please help me with that.

You should double-check how the dependency is wrapped into your application (war/ear), and make sure the scope is correct.

If you did not pack it within your application, the module has to be present on your wildfly and known to your application (e.g. jboss-deployment-structure.xml)
