No Deserializer found to deserialize a 'http://schemas.xmlsoap.org/soap/envelope/:Parameter' using encoding style 'null'

[Prasad,Bhanchand]

Hi,
Have trouble calling a .Net Service using Java SOAP Client. The error
message being returned is as follows:
No Deserializer found to deserialize a
'http://schemas.xmlsoap.org/soap/envelope/:Parameter' using encoding style
'null'
Havaing read on the net about the XML parameters, added the following to the
SOAP client code
                smr.mapTypes(
                        Constants.NS_URI_SOAP_ENC,
                        new QName("", "ClaimSearchResult"),
                        null,
                        null,
                        stringDser);
                                        
What I can make out from this is that the Web Services is executing
successfully at the .Net end but fails when the receive occurs.

Thanks in advance.
