Generating WSDL in axis2

[Ganesh Kumar]

hi,
I am using Axis2 to create a web service. I found out that the WSDL file is generated automatically in the following case:
--> Each and every operation in the service uses its message receiver as RPCMessageReceiver, RPCInOnlyMessageReceiver or RPCInOutAsyncMessageReceiver.
My question is how to generate WSDL in other scenarios. That is, if the message receiver
is RawXMLINOutMessageReceiver. Is there any tool in axis2 to generate WSDL automatically
from a Java class.

Thanks
Ganesh
