[madhukiran kommalapati]

Hi All,
This is Madhu and I am new to WebService.
I need to call a WebService, Which is in dot net, from my application.
I am trying to access it.
But I could not able to invoke the method.
I could able to create a service and Call.
But whenever I am invoking na, it is giving error saying that,

javax.xml.rpc.JAXRPCException: failed to invoke operation 'RationalData' due to an error in the soap
layer (SAAJ); nested exception is: Message[ failed to serialize interface javax.xml.soap.SOAPElemen
tweblogic.xml.schema.binding.SerializationException: mapping lookup failure. class=interface javax.x
ml.soap.SOAPElement class context=TypedClassContext{schemaType=['http://ShowData.org/']:RationalData

As RationalData is my method to invoke.

Please help me out.

Can you tell more details about how you have created your client? Also looking at exception it seems you are using JAX-RPC client. IF possible use JAX-WS client.
