VB菜鳥提問：如下問題怎么處理？？
在VB中呼叫JAVA Web servise 的代碼
Private Sub Command1_Click()
Dim soap1 As New SoapClient30
soap1.MSSoapInit "http://127.0.0.1:8080/Demo/DemoPort?wsdl"
Dim re As String
re = soap1.sayHello("123")
MsgBox re
End Sub
執行時報錯如下：
實時錯誤：“-2147024809（80070057）”
Client : Incorrect number of parameters supplied for SOAP request HRESULT=0x80070057: 引數錯誤。
-Client : Unspecified client error. HRESULT=0x80070057:引數錯誤。
同樣的方法呼叫其它 web servise 沒有問題，如：
soap.MSSoapInit "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl"
re = soap.getSupportProvince()
‘回傳成功
JAVA 中就一個類
public class Demo {
public String sayHello(String name) {
return name + ", hello!";
}
}
在Myeclipse8.5使用JAX-WS框架 自動生成wsdl(用JAVA 呼叫沒問題) 。
