I have created the following interface but while connecting the client  
throws  
=\> ““Method ExecuteTest missing or wrong number of parameters!”” error

INTERFACE = XMLRPC::interface(“srv”) {  
meth ‘string ExecuteTest(string, string)’, ‘Execute tests’,  
‘execute’  
}

have created a handler too as follows:

rpcserver.add\_handler(SimpleXMLRPC::INTERFACE,SimpleXMLRPC.new)

Am I missing something ???
