Answer 1

BeanSerializer implements Serializer so we expect, that a BeanSerializer instance is castable to Serializer. Obviously that doesn’t work in this case.

A common cause: two different implementations of axis have been loaded by different classloaders. Try to remove as many axis libraries as possible from your projects classpath(s), some library might interfere with the eclipse internal version of axis.
