The exception indicates that POF is not configured correctly. There are a few different ways to configure POF (for instance, you can do it for an entire cluster member or for individual services). I would suggest including system properties -Dtangosol.pof.enabled=true and -Dtangosol.pof.config=[your pof config.xml] to start with.

But I am getting below exception when trying to read from cache. I am using coherence 3.7.1.0 version.

Using a POF extractor/updater implies that you will be querying or modifying a field inside of your object, and you desire to do so without deserializing the object. For your example, you want to issue a query into the cache for the entire value itself (instead of just a field in the value.) In this case you would issue a query like so:

cache.keySet(new EqualsFilter(IdentityExtractor.INSTANCE, object))

and you would get back a set of keys that contain this object.
