Can I share the igniteCache object between webapps by setting custom class loaders in tomcat instance?
Note: I can not start single ignite instance at tomcat instance. I have ignite server running in one webapp, and client node in another web app. But these two webapps access POJO objects through class loaders.
I am experiencing below issue.

Caused by: org.apache.ignite.internal.marshaller.optimized.OptimizedMarshallerInaccessibleClassException: Failed to find class with given class loader for unmarshalling (make sure same versions of all classes are available on all nodes or enable peer-class-loading) [clsLdr=ParallelWebappClassLoader
  context: archive
  delegate: false
