bad types

[Mahmood Mohammed <ma...@insevo.com>]

Hi 

I wrote to execute a sample client problem, It through the following Bad
types error, 


// Set up serialization encoding for the Widget object
qname = new QName( NAMESPACE_URI, "address" );
call.registerTypeMapping( Address.class, qname,
		new AddressSerFactory(),
		new AddressDeserFactory() );

call.addParameter( "arg1", qname, ParameterMode.IN );
call.setReturnType( Constants.XSD_STRING );

Address addr = new Address();
addr.setName( "my name" );
addr.setStreet( "my street" );
addr.setCity( "my city");
addr.setState( "ca");
addr.setZip( "99899");
addr.setCountry( "USA" );

response = ( String )call.invoke( new Object[]{addr} ); // response is
name( string ).


============== ERROR =====================

I am trying to figure out what is wrong in the client problem?
Any input is appreciated?
