As of the latest SuperWaba release the xmlrpc4sw project is deprecated. It is only useful for the server examples. The client portion of xmlrpc4sw has been absorbed into the SuperWaba project. If all you want is xml-rpc client functionality in your application, please use class superwaba.ext.xplat.webservice.XmlRpcClient. Visit http://www.superwaba.com.br for SDK downloads.
