deserializer exception

Hello,
 
I am getting an exception thrown when using Axis 1.2 for invoking a 
call.  
My call is using a URL and a query as the methodname.  The 
EncodingStyleURI is 
Constants.NS_URI_SOAP_ENC
 
I keep getting the following exception:
 
No Deserializer found to deserialize a 
'http://schemas.xmlsoap.org/soap/encoding/:string' using encoding style 
'http://schemas.xmlsoap.org/soap/encoding/'.

I also tried using the SOAPMappingRegistry as was suggested in a 
previous post.  But my compiler keeps telling me that the method mapTypes 
expects (String, QName, Class, Serializer, Deserializer).  I tried using  
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new 
QName("http://schemas.xmlsoap.org/soap/encoding/",
    "string"), null, null, sd); as suggested but it did not compile.
 
 
Any suggestions??
