//说明：按指定属性访问远程的WEBSERVICE，并返回给调用函数
//参数说明：
//   wsURL:WEBSERVICE的链接地址
//   wsSoapAction:在页面中可访问到的SoapAction;
//   wsNameSpace:在页面中定义的命名空间，一般地使用:
//   wsMethod:要访问的WEBSERVICE 方法名
//   wsParam: 要使用的参数，见WSPARAM定义，
//   wsCount: 参数总数
//   sEmsg://要返回给调用函数的错误码率信息
//   sRmsg://要返回的捃执行结果信息
//返回值：
//   如果正常执行返回true,中间有问题就返回false;
