How to use xfire client to pass more than one parameter? Now I can only pass one parameter

How to use xfire client to pass more than one parameter?Now I can only pass one parameter.My code is here,and it runs well.But if I want to pass two parameter named "paraone" and "paratwo" String which value is "p1" and "p2" in the other service,How to change my code? 

     
	 Client c=new Client(new URL("http://www.webxml.com.cn/WebServices/TraditionalSimplifiedWebService.asmx?wsdl"));
	  Object[] o=c.invoke("toTraditionalChinese", new String[]{  
				        		 "冯小刚"	 
				        		});
			 System.out.print(o.length+o[0].toString());

I try to change it,but it seems wrong.
        Client c=new Client(new URL("http://www.webxml.com.cn/WebServices/otherService.asmx?wsdl"));
	  Object[] o=c.invoke("mutiparaMethod", new String[]{  
	  "paraone":"p1",
	 "paratwo":"p2"});
	 System.out.print(o.toString());
