that at Flex side I try to use as Dynamic Object. But calling Java service and obtainin this object as call result at Flex side I've got empty Object without any property. When I remove final declaration from Java fields all works correctly and at Flex I have Objects with id and name.
For a class to support AMF serialization it must follow Java bean syntax (no-arg constructor, public get/set properties or public readable/writeable variables, etc.). The 'final' keyword makes the variable unwriteable - and thus, unserializable.
