Do you have the MutableList class definition available on the machine where you are deserializing the object?

 i am running hcast server in a scala project and mutable list comes with scala

i have tried serializing and deserializing the class without hazelcast and it works fine but when i use it with hazelcast it gives me this exception. i even tried by giving my own class  loader  

is this the right way to do it ?
