下面是wsdl文件内容：

Answer 2

我的客户端调用程序片段：
....
public static void main(String[] args) throws Exception {
String endPoint = "http://localhost:7001/ServiceWeb/MaintainAccountService";
Service service = new Service();
Call cal = (Call) service.createCall();
cal.setTargetEndpointAddress(new URL(endPoint));

cal.setReturnType(XMLType.XSD_STRING);
cal.addParameter( new QName("http://www.openuri.org/","sysid"),XMLType.XSD_STRING,ParameterMode.IN );
cal.addParameter( new QName("http://www.openuri.org/","userid"),XMLType.XSD_STRING,ParameterMode.IN );
cal.addParameter( new QName("http://www.openuri.org/","appuserid"),XMLType.XSD_STRING,ParameterMode.IN );
cal.addParameter( new QName("http://www.openuri.org/","pwd"),XMLType.XSD_STRING,ParameterMode.IN );
cal.addParameter( new QName("http://www.openuri.org/","cmd"),XMLType.XSD_STRING,ParameterMode.IN );
String sysid = "11",userid = "test2",appuserid = "zhaohh",pwd = "1111111",cmd = "add";
cal.setOperationName("operateAccount");
String res = (String) cal.invoke( new Object[] {sysid,userid,appuserid,pwd,cmd} );
System.out.println("ssl="+res);}
.....

重新生成WSDL，然后重新从WSDL编译类，试试。

Answer 4

cal.setOperationName("operateAccount");这句写的有问题，你写成下面这个试一下:
cal.setOperationName(new QName("http://services","operateAccount"));
