I'm also a beginner to Axis, using it via Eclipse 3.3. I have generated a java web client to the Oracle TaskQueryService which has an anyType to represent the payload to human task activities. I don't know yet what version of Axis is being used but I am surprised that up to this time, there is still no built-in anyType deserializer in Axis. I wonder if someone already wrote one, and if not, I will have to write a simple one myself to deserialize to a org.w3c.dom.Element. So how do I specify a deserializer through a config file?
