xstream CannotResolveClassException

由 梦想与她 提交于 2019-11-28 13:22:31

When you pass the class name to the alias method you need to pass the fully qualified class name i.e the class name along with its package name.

Example : Suppose if the class Something is in the package com.xyz then you need to pass com.xyz.Something.class as the parameter

Thanks

For your question it will be useful

Spent half an evening trying to resolve similar error.
Passing a driver to xStream miraculously helped.

XStream xstream = new XStream(new StaxDriver());
